Product Principle

High-shear colloid mill main structure

The high shear colloid mill is designed and manufactured with a three-stage crushing and grinding area, including an intake shearing zone, a crushing zone, a grinding zone, and a fining zone. The flat shearing and crushing distance after the rotating stator is merged is generally 0.05mm (the adjustable distance between rotating stators is 0.01-2mm), with an outer diameter up to 600mm, a linear speed of up to 120m/s, and a normal conveying lift of up to 3-6 meters, reaching 50 meters.

High-shear colloid mill main function

High-shear colloidal mills are mainly used for the crushing and grinding of fragile particles such as crystals, lumps, agglomerates, sticky blocks, and filter cakes suspended in pipeline fluids. They more energy-efficiently enhance the reaction process of materials and effectively ensure the flow capacity of downstream pumps and valves. During the crushing and grinding process, the fluid must pass through a shear zone, a three-stage grinding area, and then be extruded in a curved manner through a channel with approximately 0.3-0.6mm teeth after being dispersed and refined ten times. This creates a high-speed, high-pressure, and high-frequency atomization phenomenon, thereby significantly improving the particle crushing, dispersion, and emulsification capabilities.

High-shear colloid mill working principle

High-shear colloid mill, under the high-speed rotation of the motor, the material enters the high-shear crushing zone directly from the inlet. Through a special crushing device, it rapidly breaks down large particles, sticky lumps, and clumps in the fluid. Then, it is drawn into the shearing crushing zone, where, due to the high-speed cutting of the rotor blades against the stator blades in an extremely narrow working channel, intense friction and grinding occur. Under the action of mechanical motion and centrifugal force, the finely crushed material is repressed back into the fine grinding zone for further grinding and crushing. The fine grinding zone is divided into three stages; as it extends outward, the precision of the grinding blades increases, the pitch decreases, the linear velocity increases, and the material becomes finer. Simultaneously, the fluid gradually extends radially in a curved path. At each stage, the direction and speed of the fluid change instantaneously, and it is subjected to millions of high-speed shearing, intense friction, compression grinding, and particle crushing per minute. After millions of high-speed shearing and grinding in three fine grinding zones, the liquid material achieves the effects of molecular chain breakage, particle crushing, and liquid-particle tearing, fully achieving the goals of dispersion, crushing, emulsification, homogenization, and refinement. The fineness of the liquid material can reach 0.5 μm, and the normal conveying height can reach 3-6 meters.
