The briquette ball press is a ball-forming device for powdered materials such as coal powder, coke powder, carbon powder, etc. The efficiency of the equipment operation and the effect of molding directly affect the economic benefits in the production process. Even the products of the same type of briquetting press manufacturers, the results of different users are different, efficient and durable is our pursuit, is there any secret here?

As long as the following points are achieved, not only the ball-forming effect of the briquette ball press is guaranteed, but also the efficiency of use is greatly improved.

The first point we want to emphasize is the parameter setting of the ball press. After the equipment is shipped from the factory to the installation, it can be pressed directly on the machine. We also need a debugging process, such as the determination of the magnitude of the pressure, the gap size of the rolls, and so on. Only by setting up these parameters to the most reasonable by commissioning can we make a good foundation.

The second point we want to talk about is the material problem, which is also a topic that is not annoying. The material needs to be processed through certain processes during the process from crushing to loading. The humidity should be reasonable, the particle size should be reasonable, the adhesive should be added, and the impurities should be too much equipped with equipment such as iron remover. This is a prerequisite for the quality of the molding.

For the long-term use of the briquette ball press, the manufacturer of the briquetting press machine once again reminds the late management and maintenance work that it is very important. Develop appropriate rules and regulations to regularly inspect and maintain equipment. It is equally important to maintain the ball press for proper operation.

First, press the ball machine parts inspection: open the internal cleaning inspection, and check the bearing, spiral, triangle lining, nozzle and other parts of the wear and tear, replace the bearing grease; sweep into the ball machine to shoot down the dust, in the process of dismantling Should also pay attention to dust removal, dust should be prohibited from invading the moving parts during the inspection; remove the inspection cover of the reducer to check the wear and toothing status of the gear; remove the bearing cover of the roller shaft to check the wear of the bearing; check the foundation bolt, Is the safety bolt loose and tightened.

Second, the use of ball pressure machine equipment lubricants and inspection: the gear oil in the open gear box should invade the gear more than 60 mm; the gear reducer plus gear oil, the filling amount can enter the gear 60 mm; the roller bearing every three Open the bearing replacement grease or grease gun once a month.

Third, pressure ball machine cylinder, motor inspection: pay attention to check whether the ball screw installation screw is loose, oil quantity, motor current, bearing heat, triangle belt walking condition cylinder pressure. The oil pressure of the cylinder should be stopped for inspection. If there is temperature change, oil pressure and other reasons, the pressure change should be injected into the new oil or run back to the corrected oil pressure period to reach the specified working pressure change. If the oil pressure system leaks, it should stop immediately. , repair the oil spill and then start.

There are also some basic knowledge about productivity:

1. The pressed material composition, that is, the degree of adhesion is very important, which is related to the efficiency of the ball and has a certain influence on the productivity. Therefore, before the ball is pressed, the material is thoroughly dry-mixed to ensure smooth production.

2. The material of the pressure roller of the briquette press is very important. If only a simple material is used, it will wear out for a long time, which seriously affects the production efficiency. Therefore, it must be cautious on the selection of the key roller components.

3. The motor and reducer of the briquetting press equipment are also very important. It is necessary to see if these motors and reducers are produced by regular manufacturers, because good motors and reducers can also indirectly improve the briquetting press. Productivity.

The improvement of the production efficiency of the briquette ball press is related to many product elements. Only by ensuring the effective and normal operation of each link can the operation efficiency be gradually improved.

Mineral powder briquetting machine is widely used in metallurgy, chemical industry, refractory and other industries. It is mainly used for the pressure ball formation of non-hydrated materials that need to be smelted by the furnace, and belongs to the category of high pressure ball press equipment. Such as: quicklime powder, iron oxide powder, copper powder, chrome ore powder, lead and zinc scrap, aluminum bauxite, non-ferrous metal powder, refractory material, ceramic material, etc., through the high-strength high pressure to make the ball with higher capacity.

Mine powder briquetting machine application principle:

The main body of the ore powder briquetting machine is powered by a variable speed motor. Through the parallel shaft reducer, the gear coupling is transmitted to the main shaft, and the movable bearing housing is equipped with hydraulic devices behind. The screw feeding device is driven by the adjustable speed motor, and is rotated by the pulley and the worm reducer to force the pressed material into the feeding port. Through the pre-pressing spiral in the hopper, the material is forcedly pressed into the middle of the pair of rolls, and the unit forming pressure of the compressed material of the counter-rotating reverse running is changed from small to large, and the forming pressure reaches the maximum at the center line of the pair of rolls. After the material passes the line, the molding pressure rapidly becomes smaller, so that the material enters the off-ball state and the ball is smoothly removed.

Analysis of application of mineral powder briquetting machine for different materials

1, quicklime

The powder of quicklime is not easy to use directly. If it is not pressed by the quicklime ball press, it is particularly troublesome in handling and transportation due to its strong viscosity. Direct use in cement production may cause poor material transport and affect the normal production of cement. The pressing of the limestone ore briquetting machine becomes more convenient and efficient in use, and can be used not only for the production of cement but also for metallurgical production.

2, iron oxide powder

Iron oxide scale is a kind of waste product produced by the rolling mill in the process of rolling blanks. The iron content is high, and direct waste causes a large waste. However, if the iron oxide scale is directly poured into the steelmaking furnace, there will be a large amount of The dust will be taken away by the hot air. In order to reduce the loss of iron, it is generally recommended to use the mineral powder briquetting machine for processing and reuse, and the benefit is extremely high. The iron oxide scale has high iron content, and can be applied to the dust removing ash which can be added to the steel mill for pressing, so that the dust removing ash can be used again, and the scraping problem of the steel industry can be solved to some extent.

3, chrome ore powder

There are many classifications of chrome ore powder, which must be in the metallurgical industry, chromite, chrome ore and other materials. Chromite is mainly used to produce ferrochrome and metal chromium. On refractory materials, chromite is used to make chrome bricks, chrome-magnesia bricks and other special refractory materials. Since the powdery material cannot be directly produced by the furnace, it needs to be pressed by the ore powder briquetting machine. The pressed ball can be used for smelting of stainless steel, acid-resistant steel, special steel and special alloy.

4, bauxite

Alumina bauxite, also known as bauxite or bauxite, is mainly composed of alumina, which is a hydrated alumina containing impurities and is a soil-like mineral. Pressing with a mineral powder briquetting machine can press the bauxite powder into a ball-shaped block to achieve the equipment required for calcination or furnace smelting.

Analysis of application prospect of mineral powder briquetting machine

1. Environmental needs

According to the development needs of the metallurgical industry, in order to reduce the environmental protection pressure of the metallurgical industry, in order to reduce environmental damage and save resources and energy, industrial enterprises need to upgrade and optimize these materials on the one hand, and also need to improve the environment through some channels. Pollution. The mineral powder briquetting machine can compress waste and powder into balls, preventing environmental pollution caused by transportation or stacking.

2, resource needs

In the past, most of the powders in China’s metallurgical industry were abandoned or changed to other uses, resulting in great waste of resources. With the increasingly tight resources and energy, the utilization of powder in the metallurgical industry has received more and more attention. However, the powder cannot directly convert the smelting conversion income, so the ore powder briquetting machine is needed to press the ball into the ball to realize recycling and increase the efficiency.

3, product advantages

The mineral powder briquetting machine is a high-pressure ball press machine that does not need to add a binder. It is not only convenient to use, but also can save the company a large part of the cost of the binder, so this is also the increasingly more and more mineral powder briquetting machine. The reason why companies are loved.

The quality of the ore powder briquetting machine is reliable, multi-purpose and powerful, suitable for large, medium and small enterprises to establish a production line with a certain production scale. It is suitable for various moldings of industrial gasification, boiler type, cold pressing type focus, ignition type coal, civil type coal, civil metallurgy, refractory materials, medicine and other materials. After many years of industrial use and improvement, the mineral powder briquetting machine has the advantages of high pelleting rate, low power consumption, compact structure and easy inspection and debugging compared with other similar products.

The mineral powder briquetting machine mainly suppresses various kinds of iron powder, mineral powder, iron oxide scale, steel slag, refractory materials, etc. Any material that needs to be smelted with powder needs a mineral powder briquetting machine.

First, the three elements that need attention in the production of mineral powder briquetting machine:

1. Due to the different sizes of coal and ball, the required pressure is also different. It is necessary to select the molding machine with the molding pressure adjustable according to the economic situation.

2. The core mechanical equipment of the briquetting machine is the forming machine, and the key component that affects the working efficiency of the forming machine is the ball rolling roller. The blank of the ball rolling roller is divided into: integral forging and casting, the casting density is small, and the structure is rough. But it is more economical. Casting has high density, compact structure, good wear resistance, long service life, good processing technology of ball groove, suitable material types, and reliable operation. Most of them are used in medium and high pressure large-scale molding machines, but the cost is high. After the manufacturing process is improved, the current equipment replacement and maintenance is more convenient, reducing the difficulty of user maintenance.

3. The ball produced must be dried for sale or use. The current use is preferably a high-efficiency, easy-to-use vertical dryer or flap drying equipment.

When using the mineral powder briquetting machine, it is necessary to pay attention to the above problems in order to produce a good product when pressed.

Second, the installation instructions of the mineral powder briquetting machine:

Convenient installation is the characteristics of the briquetting machine, but the humanized design of different brand briquetting machines is still inconsistent. Many international famous brands provide a set of instant and effective installation, debugging and failure in addition to providing humanized products. Exclude the solution. Here, briefly put forward the common precautions and effective methods of troubleshooting in the actual project. Only the correct installation and proper maintenance can make the briquetting machine play its proper glory.

Before installing the briquetting machine, the pipeline should be laid in strict accordance with the electrical specifications, and the strong electric and weak electric signal lines should be isolated and worn to avoid interference. In the outdoor open environment, independent external lightning protection measures should be taken. The ball machine itself should also be well maintained. Grounding, to prevent static electricity accumulation, etc. affect the ball machine. When installing, properly connect the power cable, communication cable and video cable. When connecting, carefully refer to the installation instructions to confirm the communication method and the corresponding pin definition. Generally The equipment should be installed in the later stage of construction to avoid a large amount of dust on the construction site from invading the ball machine, directly affecting its use effect and life.

Third, the production and maintenance of mineral powder briquetting machine

Some of the basic problems limiting the shape, size and distribution of the ball and socket are obvious when designing the surface of the ore powder compactor. First of all, it must be recognized that the ball socket is never completely closed during the ball pressing process. Once the lower end of the ball is opened, the pressure at the upper end of the ball pushes out the lower part, which is important for demolding. However, as long as there is a tangent to the lower side of the stick at the lower end, the ball is easily destroyed under this pressure. This is one of the reasons why cylindrical balls cannot be made. The most advantageous shape is the drip type. As the length of the ball on the circumference of the wheel and the diameter of the wheel increase, the above effect is weakened. In particular, a small ore powder briquetting machine with a fixed nature theory needs to use the entire stick surface for the ball. The non-working platform between the elliptical ball sockets is large. The ball material is overpressured in these areas and determines the highest mechanical load of the ore powder briquetting machine, while the material in the ball socket is not compact. So all the pressure is used for forming and compacting. This effect imposes quite severe restrictions on the design of the wheel, and many people want to solve this problem. The left-hand wheel is horizontally moved by the eccentric transmission so that the lower side of the ball socket remains closed. The mineral powder briquetting machine is completed until the ball pressing process is completed. Then, the ball is released when the upper side of the ball is closed.

The diameter of the material used by the mineral powder briquetting press during ball pressing affects the working efficiency of the briquetting machine equipment, which has been confirmed to a large extent, so before the material of the mineral powder briquetting machine enters the inside of the briquetting machine We must check the materials to ensure the particle size and uniformity of the materials, so as to ensure that the components of the mineral powder briquetting machine are not damaged by materials of different sizes, and ultimately affect the working efficiency of the mineral powder briquetting machine.

During the working process of the mineral powder briquetting machine, if the particle size of the material is not uniform, the mechanical energy is completely converted into kinetic energy when the material is pressed against the roller, so that the mechanical energy of the ore powder briquetting machine is not completely used in the material. The extrusion efficiency of the briquetting machine will be reduced, so controlling the particle size and uniformity of the material is an important part. Otherwise, it may affect the working efficiency of the briquetting machine equipment and may also cause the ore powder pressure. Damage to the components of the block machine.

When the briquette ball press is working, it is necessary to feed the material into the equipment, and then pressurize the roller, and the finished ball is detached and transported to the product warehouse through the conveyor. Generally, the filling methods we have seen include: falling in, inhalation, top filling, and lower filling.

Fall into the law

This is a traditional method of conveying the material to the feed port of the briquette press by a box feeder, and automatically feeding the stirred powdery material into the equipment by free fall mode. When filling the powder by this method, filling Speed ​​and uniformity often depend on the size of the cross-sectional area of ​​the cavity and the speed of the powder.

Inhalation method

Since the particle size of the powder generally used is between 40 and 200 & mu; m, if the drop method is used, when the cavity is narrow, the powder is not easy to enter and the speed is slow, which will affect the use efficiency of the molding machine. In order to improve this phenomenon, the inhalation method can be used. That is, when the powder filling box reaches above the cavity, the middle mold moves up, which causes vacuum suction, which accelerates the entry of the powder into the pair of rolls and the completeness of the filling. For materials with complex shapes and sharp corners, or for thin wall materials less than 1 mm, it is of great help.

Filling method

After the powder is filled into the counter roll, it is moved up to the height of the die face, which is also very helpful for the thin-walled parts, because the gap between the mandrel and the middle die is small when the thin-walled parts are formed, which is easy to cause bridging, which hinders the After the powder is dropped, if the mandrel is first below, the briquette ball press can be added to the roll space to facilitate filling. After the filling is completed, the upward movement can improve these troubles.

Under filling method

When the filling is completed, the middle mold and the upward movement are moved upwards to lower the powder relative to the mold surface, which prevents the powder from being sprayed outward when the upper punch moves downward, and can reduce the push angle or circle due to the middle mold. The arc angle causes some powder to get stuck between the upper punch and the middle die.

Precautions for material filling of briquette ball press:

1. The structure of the crusher has a large impact on the crushing size.

2. Mixing mode, stirring strength and stirring effect of the mixer, poor tolerance of materials and adhesives, and poor molding plasticity.

3. The feeding method and feeding quality are inaccurate and unstable.

4. The raw coal belt conveying material in front of the crusher is easy to be discontinuous and uniform, and the crusher has unstable production capacity and particle size control, which affects the subsequent process, and should be weighed by belt.

5, the molding machine feed must be continuous, uniform, and not shed.
1) After mixing and mashing, the agglomerated materials should be mixed or homogenized twice to make the molding machine uniform, control the molding compression ratio, and the ball forming rate is high and the strength is good.
2) Solve the problem of raw coal bunking of materials for mixing and smelting. Generally, the loader is used to put the material into the silo, and the material has large viscosity and also has a drop, which is easy to block the discharge port of the silo, resulting in discontinuous feeding, and occasionally, the molding machine runs in this state, and the scraping material is large. The ball formation rate is low.

6. The selection principle of molding pressure is not the greater the pressure, the better the molding pressure can be selected under pressure adjustable conditions to avoid the phenomenon of pressure feeding and rebound (hemisphere).

The elasticity of coal refers to the deformation of coal produced by external force, and the degree of recovery of deformation after external force is removed.

The elasticity of coal is generally expressed by the relative expansion ratio after the demolding of the briquettes. The greater the elasticity of the coal, the looser the coal after press forming and the lower the strength.

The elasticity of coal is related to the following factors:

 

1, the degree of coalification

According to the degree of coalification, coal is divided into peat, lignite, bituminous coal and anthracite. As the degree of coalification increases, the elasticity of coal increases. The elasticity of anthracite.

2, the level of granularity

In the same coal, the finer the particles, the more elastic and the poorer the formability.

3, the moisture of coal

The same coal type, generally the greater the external moisture, the greater its elasticity.

In addition, the minerals in the coal also have a certain influence on the elasticity. The coal with large elasticity is difficult to form, and the strength after molding is also low. When the mold is released, it is often cracked and swelled due to elastic expansion, so for the coal with large elasticity Try to reduce the elasticity and then reshape.

The main raw material of clean briquette is anthracite. The anthracite has large elasticity and poor plasticity. To pay attention to this feature, pay attention to the following matters in production:

 

1, the crushing process

After crushing, the particle size of the coal should be controlled below 3 mm, of which more than 70% is more than 1 mm. The upper limit of the specified particle size is to prevent the secondary crushing of the coal in the forming process and affect the strength of the briquette. The specified lower limit is advantageous for reducing the elasticity between the particles while reducing the amount of binder added and improving the burning performance of the briquette.

By the way, the coal moisture into the crusher is generally controlled below 15%, otherwise it will affect the crushing effect.

2, kneading process

The kneading process is a general term for mixing and kneading. The mixing is to mix several materials and water uniformly by mechanical agitation.

Kneading is to uniformly distribute water and binder on the surface of the coal particles so that it is closely adsorbed on the surface of the coal particles to form a hydrated film. In addition, the bulk density of the coal material can be increased, the elasticity between the coal particles can be eliminated, and the molding is facilitated.

Commonly used kneading equipments include twin-shaft mixers, wheel mills, vertical kneaders, etc.

3, purification process

The deuteration process is to infiltrate the binder into the interior of the coal particles, and at the same time increase the bulk density of the coal, eliminate the elasticity between the coal particles, and increase the strength of the briquette.

Some clean coal production lines do not have a deuteration process. If you increase the density of coal and eliminate the elasticity between coal particles, Xiao Bian recommends that you look at the coal for a period of time before the molding process.

The simmering time is generally 24 hours and is adjusted as the temperature changes.

4, molding process

When the coal particles are pressed, they will be elastically deformed, and the mechanical energy input from the power will be stored in the briquette. When the forming pressure is eliminated, this part of energy will be released, and the volume of the briquette will expand. Anthracite has large elasticity and high expansion ratio, so it adopts low pressure molding, and the molding pressure generally does not exceed 25 MPa. The pressure excessively generates cracks on the surface of the briquette, reducing strength and water resistance.

The representative position of the briquette press in the ball press industry is the earliest and most consolidated, because the use of coal resources in China is inseparable from the briquetting press. At present, the commonly used pulverized coal forming methods mainly include cold press forming of a binder and cold press forming without a binder.

1, with adhesive cold forming

That is, the binder is added to the pulverized coal and then press-formed. In the case where binderless molding such as bituminous coal or anthracite is difficult, the cold press forming method of the binder is generally used in the industry. At present, most of the briquettes used in China’s synthetic ammonia industry also adopt this molding method, because a suitable binder having a mass ratio of 5% to 20% is added to the pulverized coal of these coal types, and the molding pressure is applied by the action of the binder. It can be reduced to 15 to 50 MPa, so it is easy to implement industrially. However, it must be pointed out that due to the use of adhesives, the following problems will occur:

(1) Reducing the fixed carbon content of briquette, especially when using inorganic substances such as lime, cement and clay;

(2) Generally speaking, the price of the binder is higher than that of the pulverized coal. Although the amount used is small, the cost of the briquette is also increased;

(3) The binder itself needs to be treated, and it must be uniformly mixed with the pulverized coal, and later consolidated, etc., so that the molding process is increased and the process is complicated;

(4) The amount of briquette used in industry is large, and the amount of binder needs to be correspondingly large. The binder should have sufficient sources. Based on these circumstances, it is necessary to strengthen the research on the binderless molding method from a long-term perspective. Of course, applications with adhesive molding will continue to evolve.

2, no binder cold forming

That is, the pulverized coal is formed without any binder and by the action of external force. This method has been widely used in many countries to make peat and lignite briquettes as household fuels or industrial fuels. For bituminous coal and anthracite, because of their high degree of coalification, it is difficult to form a pulverized coal without adhesive. At present, the binderless molding process has not been widely used in the industry, but the research work in this area has not been interrupted in the world. The clean coal wet coal rod (wet coal rod) used in China’s synthetic ammonia industry is also an example.

Pulverized coal binderless molding does not require the addition of any binder, which not only saves a large amount of raw materials, but also maintains the carbon content of the briquette, and simplifies the molding process, etc. It is a pulverized coal molding; an important development direction.

Most of the ball sockets of the ball press roll are about three centimeters, and of course they are too big or too small. Today, I would like to remind the majority of users, do not use the roller skin with small ball and socket diameter. If there is a good heart, it is best to dispel it early, because we have encountered similar situations for this, but the results are all Replacement, completely unusable. Why is the diameter of the ball and socket of the ball presser’s roll skin not too small?

The roller presser is the most important decisive component of the size and size of the press ball machine. It is crucial for the whole machine and determines the pressure of the whole machine. It can be said that if the roll skin is not suitable or the quality is not good. The whole machine can’t work. Therefore, the design of the roll skin is quite important. Of course, these manufacturers know it. The problem is that many customers are not clear. Sometimes when the customer orders the machine, the size of the roll ball socket is very small for the manufacturer. It’s very difficult to do, but it can be done, but it can’t be used effectively after it is made. First of all, it can’t reach the pressure. Secondly, it is difficult to support the ball. It needs to explain to the customer one by one.

The size of the ball sleeve of the ball press can not be too small. If it is too small, the pressure of the whole machine will not be reached, and it is also a problem when the ball is placed, and the small ball nest is made. It is also quite troublesome at the time, and the production cost is much higher than normal. Therefore, the size of the roll ball socket cannot be too small; if the roll skin size is too large, it is quite convenient for production. It is also very convenient for the user, but it is also a problem after the event. In the large case, the hardness will definitely decrease, and the strength may not meet the requirements for use. Therefore, the size is not too large.

The ball and socket size of the roller of the ball press is still moderate. If it is too large or too small, it will affect the normal use of the whole machine. Of course, the manufacturer has no problem, so remind the customers that they need to pay attention to this when ordering. Point, otherwise you can not use it according to your requirements, some good manufacturers will give you a reminder, but some manufacturers do not care if you use it afterwards, your request is satisfied But not being able to use afterwards is not their problem. Therefore, for the majority of users, this is a must pay attention.

The shape and size of the ball socket of different types of ball presses will vary from material to material to meet various requirements. For example, for a dry powder ball press, it is necessary to select a flat ball socket, and the ball nest is not large and shallow. The main reason is that the dry powder ball press does not allow any sticking when pressing the raw material. Mixing, if you use deep ball sockets and large ball nests, the ball formation rate is not high. It is even difficult to shape.

For the briquette ball press, the ball socket should be selected as much as possible, and the ball socket should be set to a spherical shape, so as long as the moisture and the amount of the binder are controlled, the yield of the finished ball is as high as 95%. And the strength of the ball is very good. If you can’t do it once, you can try to press the ball twice to ensure the ball rate and strength. Therefore, the design of the roll skin of the ball press equipment should also refer to and follow other aspects.

The rational and effective use of waste is advocated by China, and it also protects the environment. Today, large-scale desulfurization gypsum ball presses play a huge role in the waste of resources, not only to contribute, but also to increase profit margins for customers. .

Large-scale desulfurization gypsum ball press is suitable for various forms of industrial gasification, boiler type, cold-press type focus, ignition type coal, civil type coal, civil metallurgy, refractory materials, medicine and other materials. Desulfurization gypsum ball press has been used and improved for many years. Compared with other similar products, the desulfurization gypsum ball press has obvious advantages such as high pelleting rate, low power consumption, compact structure and easy maintenance. Mainly suppress all kinds of iron powder, desulfurization gypsum, iron oxide scale, steel slag, refractory materials, etc. Any material that needs to be smelted with powder needs a desulfurization gypsum ball press.

First, the three elements that need attention in the production of desulfurization gypsum ball press:

1. Due to the different size and type of coal and ball, the required pressure is also different. It is necessary to select the molding machine whose molding pressure can be adjusted according to the economic situation.

2. The core mechanical equipment of the ball press molding equipment is the forming machine, and the key component that affects the working efficiency of the forming machine is the pressure ball roller. The blank of the pressure ball roll is divided into: integral forging and casting, the casting density is small, and the structure is rough. But it is more economical. Casting has high density, compact structure, good wear resistance, long service life, good processing technology of ball groove, suitable material types, and reliable operation. Most of them are used in medium and high pressure large-scale molding machines, but the cost is high. After the manufacturing process is improved, the current equipment replacement and maintenance is more convenient, reducing the difficulty of user maintenance.

3. The ball produced must be dried before it can be sold or used. The current use is preferably high efficiency, good use of vertical dryer or flap drying equipment. The special design structure of large-scale desulfurization gypsum ball press has compact structure, convenient maintenance, simple operation, short process flow, low energy consumption and low failure rate. The main roller part adopts high-quality alloy steel material to greatly improve the wear resistance and pressure resistance. The desulfurization gypsum ball press machine has a long service life. It also better reduces the energy of the equipment and has a good effect on the protection of the environment. It is suitable for the pressing of various materials. It is characterized by large production capacity and wide application range. The larger the production capacity of the desulfurization gypsum ball press, the smaller the energy consumption, which saves the production cost for the user and greatly improves the economic benefit. Its products solve the problem that users are difficult to suppress high-humidity materials, save resources and reduce the cost of customers.

Second, in addition, in the production of ball press equipment, factors affecting safe production include environmental factors and human factors. Where is it embodied? The following is a detailed introduction.

1. Environmental factors
There are many environmental factors that affect production safety in the operation of the ball press equipment production line, such as engineering geology, meteorological conditions, noise, ventilation, lighting, etc., and these factors have complex and varied characteristics, especially meteorological conditions such as When temperature, humidity changes, or winds, heavy rain, hot weather, severe cold, etc., the operation and working efficiency of the production line will be directly affected. In severe cases, the production line will be shut down and the equipment will be damaged.
Environmental factors can be said to be objective factors affecting the safety level of the pressure ball machine production line. The objective factors are mostly unchangeable. They can only adapt to the defense measures to reduce the impact and harm.

2, human factors
People are the creators of security, and their colleagues are also powerful destroyers. The operators directly control the operation of the equipment. If careless and careless about the management and use of equipment according to the equipment use rules, equipment damage and safety will be greatly increased. The probability of accidents will cause the production line of the ball press to stop or cause casualties, so people are the most important factors affecting the safety of the production of the ball press equipment.

However, it is considered that the factors are subjective and controllable. Therefore, to ensure the safe operation of high-pressure ball presses, ore powder ball presses and other production lines, it is necessary to take the core and use people as the driving force for safety control, and to exert human enthusiasm and creativity. Say you can start from a few points:

1. Intensify safety production publicity and education and special rectification activities for safety production, and further verify the safe production base of the ball press production line through inspection activities.

2. Analyze various factors affecting quality and safety in advance, find out the leading factors, take measures to focus on control, eliminate the quality problem in the bud, and prevent it from happening.

3, the operator should have superb technology and meticulous work style, should strictly implement the quality standards and operating procedures, with excellent work quality to ensure the safety of the production line.

4. The system of customizing, definite, and post-responsible should be implemented in accordance with the principle of man-machine fixation. Strictly analyze the quality of materials used in ball-pressing equipment, and identify problems in time to ensure quality and safety.

As a company, safety production is one of the top priorities. Because safe production not only ensures the personal safety of workers, but also ensures the normal operation of the machine. Safety production includes inspections before the machine is running, precautions during work, and maintenance knowledge. Let me take a look at the routine check before the ball press is turned on:

First, adjust the tightness of the pressure belt of the ball press, the tightness requirements; press the V-belt with the force, the droop is not more than 1 cm.

Second, adjust the gap between the two rollers of the ball press to ensure that it is the best between 0.5-1 mm. The main method is to press down or lift the iron.

Third, let the pressure ball machine empty test run, no abnormal phenomenon began to start the test load.

Fourth, inspection of the ball machine ball out of the situation, there can be no sticky roller does not release the phenomenon. If it is necessary to polish the forming rolls, the method is to repeatedly test the pressure on the machine with dry loose coal until all the mold is released.

Improve motor performance

First, the stator winding is changed into a star-delta hybrid series winding, and the star-connected or delta-connected method according to the load is lightly and heavyly converted, which is beneficial to improve the magnetomotive force waveform generated by the winding and reduce the working current of the winding, thereby achieving the purpose of high efficiency and energy saving.

Second, the reasonable adjustment of the type of coal briquetting machine motor can make the motor run in a high-efficiency working area and achieve energy-saving purposes.

Third, the cross-section from the joint to the electric energy meter and the wire leading to the motor should meet the current carrying capacity, and the wire should be shortened as much as possible to reduce the wire resistance and reduce the loss. The above measures can be adopted separately or multiple times at the same time. In short, it takes some necessary technical energy-saving measures for the briquette briquetting machine motor, which is beneficial to the safe and stable operation of the power grid, and also enables users to reduce electricity bills.

Fourth, improve the efficiency of the coal briquetting machine motor itself, such as changing the motor self-cooling fan to its cooling fan, can disable the cooling fan when the load is small or the outdoor motor is in winter, which is beneficial to reduce energy consumption.

Fifth, the newly purchased briquette briquetting machine should first consider the selection of high-efficiency energy-saving motors, and then consider other performance indicators as needed to save energy.

Sixth, the use of other continuous speed control mode. Such as the use of voltage regulator, pole-changing motor, electromagnetic coupling governor, frequency control device.

Seventh, reasonable installation of parallel low-voltage capacitors for reactive power compensation, effectively improve the power factor, reduce reactive power loss, and save energy.

Four transmission modes

1. The briquetting machine motor drives the hard tooth surface reducer. The low speed output of the reducer is parallel to the two axes. The gear roller drives the ball roller to operate relatively. The feeding method adopts the screw propulsion and exhaust device, which is suitable for dry powder molding. This type of transmission, the roller block rotates smoothly, the gear life is long, the transmission torque is large, and the roller surface line pressure is up to 100KN or more. It is generally applied to the dry powder forming pellet production line of metallurgical and refractory enterprises. Due to the insufficient development of this type of machine in China, there are still few single machines with large output so far.

2. The motor drives the reducer, and the low-speed output shaft of the reducer is a single shaft. The coupling moves the pair of large gears on the pressure roller to move relative to each other, that is, the suspension gear. This type of transmission is commonly used by most manufacturers of briquetting machines. Due to its simple structure and low price, it is widely used in China.

3. Improved type; that is, changing the hanging gear to the gear box increases the transmission torque and increases the production volume. The price is much lower than that of the dual output shaft, which has been gradually promoted in China.

4, open transmission mode, that is, the motor directly drives several gears of open gear transmission, limited to small test or very low production use, has been gradually phased out in the domestic market.

The sales network has established a good business relationship with customers and can solve problems for you at any time.

Iron and steel enterprises aim at full utilization of solid waste and zero emissions, and most of them have made great progress. The combination of specialized centralized management and various management systems has also achieved initial results. At present, all steel companies have basically completed the full treatment and recycling of iron-containing resources in industrial solid waste. The basic sequence is: solid waste resource recovery → sintering → blast furnace → steelmaking → steel rolling, the so-called “large recycling model”. However, its utilization is still in the low-level, low-efficiency, low-value-added, low-level utilization, which is characterized by non-optimal economic and environmental benefits, such as the use of iron oxide scale, converter mud and gas mud, so it is developed in depth and The research on high-value utilization needs further research and development. This paper will explain the deep development of metallurgical waste from six aspects.

1. Strengthening the slag grade and quality of steel slag flux slag

The flux slag recovered after crushing magnetic separation of steel slag has been used by the sinter plant, and the ratio is generally about 115%. However, the blending of flux slag will affect the grade and quality of sinter, mainly because the water wetting property and pelleting performance of the steel slag are worse than that of iron ore powder. The amount of sinter plant is limited or even stopped, so that the flux slag utilization and export pressure Increase. Therefore, the experimental research on strengthening granulation of sinter and steel slag flux slag should be strengthened, and the suitable amount of steel slag flux slag should be discussed to ensure that the sintering speed, sinter strength, yield, utilization coefficient and sinter reductivity meet the requirements.

2. Further development of steel slag in cement production

Steel slag should be further strengthened for production test research and production verification of cement plants, and the optimal process control parameters for steel slag cement production should be explored to increase the amount of steel slag incorporation.

3. Development of steel slag powder production

The use of steel slag powder in cement and concrete is the best way to utilize high-value resources of steel slag in China. The steel slag with specific surface area of ​​400m2 /kg can replace 10%~30% of cement in equal amount, and can be directly used in concrete construction engineering, which can improve the late strength of concrete, improve wear resistance, frost resistance, corrosion resistance and cost. It is 30% lower than cement and can reduce the construction cost. It is the raw material for high performance and high durability concrete. At present, the annual output of steel slag powder has reached 3 million tons, and the products are mainly used for engineering construction. In the development of steel slag powder production, it is necessary to strengthen the selection of grinding equipment and the control of the grinding process.

4, steel slag for road materials and building materials

The key is to solve the problem of the stability of steel slag. It is necessary to improve the existing hot slag treatment process, and strengthen the technical research of steel slag hot slag treatment process and equipment. The research and development of the steel slag hot slag treatment and the hydraulic steel slag non-burning load-bearing bricks in Hunan’s Handan Iron and Steel Co., Ltd. achieved good results. Agrwal G and others at Alfred University in the United States use steel slag to produce CaO-rich glass-ceramics that are more resistant to corrosion and corrosion than ordinary glass.

5. Accelerate the development and utilization of gas mud

After the gas is re-elected, the carbon content in the tail mud is as high as 35%, and the carbon in the gas is recycled to replace the anthracite used in the blast furnace. Carbon powder can be recycled using a new recycling process.

6. Develop metallurgical dust sludge to produce coolant and slagging agent for steelmaking

The comprehensive utilization of converter mud, dust ash, iron oxide scale, etc. has always adopted the “recycling-processing-sintering utilization” process route, and is not a deep-developing and high-value utilization method of solid waste resources. The use of metallurgical dust sludge such as converter mud to produce coolants and slag-forming agents that meet the requirements of steelmaking, so that the utilization process of metallurgical dust sludge can be reused from the past “waste-burn-iron-steel” large-scale recycling to “waste-steel” small cycle. The use of transformations makes the system less energy-intensive, less polluting, less costly, and more profitable.

7. Pressing metallurgical waste into a stamping process

Generally, the high-pressure briquetting machine can extrude metal materials such as metal scraps, steel shavings, scrap steel, scrap iron, scrap copper, aluminum scrap, aluminum shavings, disassembled car shells, and waste oil drums into various shapes such as cubes and cylinders. Qualified charge. Easy to store, transport and recycle.
