Horizontal power mixer is composed of frame, cylinder, main shaft, mixing tools, fin plate, composite wear-resistant liner, transmission device and control system. Inspection holes are provided on both sides to facilitate the operator to inspect and maintain the mixing tool.
The main mixing objects of the horizontal powerful mixer: the mixing of various solid materials and powders, and the high-precision mixing of these materials after adding the binder. It has the remarkable points of stable operation, sturdiness and durability, high mixing precision, stable mixing fruit, continuous operation and no impact on the environment around the mixing equipment.
Advantages of horizontal powerful mixer
1. Continuous feeding and discharging, efficient mixing
The horizontal powerful mixer adopts a single-axis multi-cavity design, the teeth are arranged in different geometric shapes, and the materials are placed in the front and rear movable curtains of the mixer body to realize the cross between the materials. mixing. This horizontal powerful mixer is particularly suitable for mixing powders and powders, as well as powders and a small amount of liquid (binder), or large specific gravity materials.
2. Stable operation of horizontal powerful mixer
The horizontal powerful mixer has a horizontal structure. When the mixed material enters the mixer through a belt, a rubber gasket is installed in the mixing barrel to prevent adhesion. The mixing tool is made of high wear-resistant steel and welding wear-resistant electrode, and the horizontal strong mixer has a long service life. Reasonable design, stable work and convenient maintenance.
3. Strong sealing, little impact on the environment
The horizontal powerful mixer is a horizontal closed cylinder structure, the inlet and outlet are easy to connect with the dust removal device, and the mixing area has a small environment.
Working principle of horizontal powerful mixer
The horizontal powerful mixer is composed of a frame, a cylinder, a mixing tool, etc., a transmission system and a control system. Among them, the transmission system is composed of a hydraulic coupling, a triangle belt, a torque sensor, an explosion-proof motor, and a hydraulic motor.
During the work, the mixing tool arranged in the middle of the equipment and 13 or 26 mixing rake teeth in different directions on the mixing tool will enter the material of the mixing equipment according to the form of convection, and the material will be strongly sprinkled, sheared, spattered, Exchange, etc., so that the materials are fully mixed in the barrel of the mixer and moved to the discharge end of the mixing device. In this way of mixing, the materials to be mixed are not easy to agglomerate or agglomerate in the mixing equipment.
In the process of mechanical mixing of materials, there are the following five ways:
(1) Shear mixing forms shear surfaces with each other in the materials, so that the mixing of materials takes place.
(2) Convective mixing of many agglomerated material particles moves from one place of the mixer to another for relative flow.
(3) The particles of the diffusion mixed mixture move in a single particle as a unit, similar to the molecular diffusion process in gas and liquid. It is an irregular movement, especially when the particulate material (dust) is in vibration or fluidized state, the diffusion effect is extremely obvious.
(4) Impact mixing causes the particles of a single material to disperse under the impact of the material and the wall shell.
(5) The particles of the crushed mixture are deformed and crushed.
Five mixing methods exist simultaneously in each mixing process, but the main three are the first.
Taking the batch mixer as an example, the mixing process can be divided into three stages. First, the particles penetrate and slide from one part of the material to another part in a mass, and convective mixing occurs. Secondly, the particles of different ingredients are gradually dispersed across the newly formed interface for diffusion mixing. Finally, under the effect of self-weight and centrifugal force, particles with similar shapes, sizes and densities will accumulate in different parts of the mixer, called particle aggregation.
The first two effects are helpful for mixing, while the latter is a separation effect that prevents the particles from being evenly distributed. These three phases occur simultaneously in the mixer, but in different mixing time, the degree of effect is different.
