 Multi-stage shearing colloid mill working principle: Multi-stage shearing graphene colloid mill is mainly due to shearing, dispersing, emulsifying, homogenizing, depolymerizing, stirring, mixing, crushing and pulverizing. The lower material is directly grounded from the inlet by the thruster device directly into a shearing and crushing system, and is effectively crushed. Through a special pulverizing device of two grinding and refining systems, some large powders in the fluid are viscous. Particles such as blocks and briquettes are rapidly broken, and then finely pulverized by suction shearing and crushing. In the very narrow working aisle, the rotor blade and the stator blade are relatively high-speed cut, resulting in strong friction and grinding and crushing. Under the action of mechanical motion and centrifugal force, the pulverized and refined material is re-pressed into the refining zone for grinding and crushing. The fine grinding is divided into three to four grades. The more outwardly, the higher the accuracy of the first-stage grinding disc, the smaller the pitch. The longer the line speed, the finer and finer the material, and the fluid gradually curves toward the radial direction. The direction velocity of each fluid changes instantaneously, and is subjected to tens of millions of high-speed shears per minute, strong friction, extrusion grinding, particle pulverization, etc., in tens of millions of high speeds passing through three refining zones. After shearing, grinding and pulverizing, the liquid molecular chain breakage, particle pulverization, liquid particle tearing and the like are produced to fully achieve the purpose of dispersion, pulverization, emulsification, homogenization and refinement. Special low-temperature industrial mining requires that the pulverized material passes through the state of cooling at a low temperature, enters the mechanical pulverizer cavity and rotates relatively high speed through the colloid grinding wheel (stator and rotor), and the material and the blade, the toothed disc, and the repeated impact between the material and the material. Under the combined action of collision, shearing, mixing, stirring, emulsification, homogenization, grinding and friction, the fineness can reach 0.5~8um, which is the ideal effect of ultrafine particle crushing. At the same time, the conveying head can reach 5-30 meters, and the special multi-stage shearing conveying Yang can reach 30-60m.
