Sludge Briquetting Machine
Sludge is a solid precipitation material produced by water and sewage treatment processes. The sludge briquetting machine is mainly used for the ball making of sludge, directly into the furnace for smelting, to increase the added value, and also has a good forming effect on many types of materials such as coal powder, clay and carbon powder.
The sludge briquetting machine combines sludge characteristics, reasonable design, and processing with high-quality materials. This machine has the advantages of strong stability, abrasion resistance, high production quality, good performance, easy operation, small investment and quick results.
Sludge briquetting machine structure
1. The feeding part mainly realizes quantitative feeding to ensure that the material enters the pair of rollers evenly. If the feeding amount is too large, the electric power of the feeding device will be overloaded; if the feeding amount is too small, the goal will not be achieved. Therefore, skilled operation skills are an important condition to ensure the normal operation of the ball.
2. For the transmission part, the main transmission system is: motor-delta belt — reducer-open gear — roller.
3. The forming part mainly refers to the main part, and the core part is the roll. The machine can adjust the pressure according to the requirements of the ball density, and the production is flexible.
Material requirements of sludge briquetting machine
1. The sludge briquetting machine should control the particle size of the material less than 1mm to 30-40%; the 1mm to 2mm particle should be 30-40% and the particle size should be less than 3mm.
2. The moisture content should be controlled at 8-10% (the amount of moisture has a great impact on the ball formation, a little more and a little difference, to ensure uniform moisture, special attention should be paid).
3. The material is not allowed to have iron blocks or other high-hardness-like debris in order to avoid damage to the sticks and shafts of the molding machine. The user department should install iron removal parts in the process preparation.
Working principle of sludge briquetting machine
The sludge briquetting machine is installed on the centerline of the pair of rollers because of the pre-pressing screw, and the pre-pressing screw feeding is the main way of feeding. Therefore, the material in the direction of the center line of the drop is subjected to a forced external force from the pre-pressing spiral, and the chemical composition of the material and the properties of the cement will not change under the external force. But microstructures can change significantly. With the continuous increase of the external force, the material particles move, and the structure of the material changes. The microstructure is changed from the original granular overhead structure to the granular mosaic structure. In a dense state. Due to the constant moment characteristics of the electromagnetic speed-regulating motor, the sludge ball press can maintain a constant feed pressure to stabilize the pellet quality when the screw press amount of the screw feeder is equal to the amount of material required by the host. If the feeding amount is too large, the electricity of the feeding device will be overloaded; if the feeding amount is too small, no ball will be formed.
Production capacity
According to the sludge briquetting machine production capacity, it can be divided into different models, and the common models are 1250, 1000, 850, 650, 360 and other models. The larger the model, the stronger its production capacity. In addition, the specifications of the forming roller diameter and roller surface race of the sludge briquetting machine are the main factors that determine the production capacity.
