 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.

Main features of multi-stage shear graphene colloid mill
1. The motor adopts high-quality motor such as ordinary type and explosion-proof type to ensure long-term use without quality problems, and quiet design, no vibration, no noise, good dynamic balance effect, convenient installation and small size;
2. Applicable to all kinds of liquid medium materials, the density of small-sized materials should be less than 300-3000 centipoise; medium-weight materials should be less than 10,000 centipoise; Medium of 10000-100000 centipoise;
3. Can replace and be better than stone grinding, sand mill, ball mill, milk homogenizer, emulsifier, three-roller, masher and so on. According to the customer's special requirements for the different acidity, alkalinity, consistency and other properties of the processed materials;
4. Graphene colloid mill has strong mixing and homogenization, dispersing and emulsifying ability and stronger crushing and grinding, crushing and conveying functions;
5. Graphene colloid mill grinding and rotating stator is made of high quality stainless steel 304, 316, 316L, 2520, special stainless steel and alloy steel for nitriding treatment or tungsten carbide treatment to enhance the hardness of the surface;
6. Graphene colloid mill, so the parts are made of forged finishing, no dead angles and flaws, to achieve corrosion resistance and wear resistance;
7. Graphene colloid mill has strong conveying capacity and the head can reach 20 meters. Continuous operation and gap operation do not affect equipment life;
8. The gap can be adjusted, the adjustment distance is 0.01~2mm, and the small refinement degree can reach 0.5~8um;
9. It adopts mechanical water-cooled high-temperature double-sided alloy seal, as long as there is no problem with the sealed coolant overflowing and idling.
The core function of the product is the crushing, conveying, mixing, dispersing, homogenizing, emulsifying and refining of materials.
It is widely used in food, pharmaceutical, daily chemical, fine chemical, petrochemical, paper industry, pesticide and fertilizer, plastic rubber, paint and coating industries.
