Product Principle

High-shear colloid mill main structure

The high-shear colloid mill is designed with a three-stage grinding area including an intake shearing zone, a crushing zone, a grinding zone, and a refinement zone on the rotating and fixed rotors. The planar shearing and crushing distance after the rotating and fixed rotors are combined is generally 0.05mm (the adjustable distance between the rotors is 0.01-2mm), with an outer diameter of up to 600mm, a linear velocity of up to 120m/s, and a normal conveying height of up to 3-6 meters, reaching 50 meters.

High-shear colloid mill main function

High-shear colloidal mills are mainly used for粉碎 grinding and refining a variety of fragile particles such as crystals, lumps, agglomerates, sticky blocks, and filter cakes suspended in pipeline fluids. They enhance energy efficiency in the material reaction process and effectively ensure the flow capacity of downstream pumps and valves. During the grinding process, the fluid must pass through a shear zone, three grinding zones, and undergo ten stages of dispersion and refinement before being curved extruded through a channel with approximately 0.3-0.6mm teeth, creating a high-speed, high-pressure, and high-frequency atomization phenomenon. This significantly improves the particle's粉碎 dispersion and emulsification capabilities.

High Shear Colloid Mill Working Principle

High-shear colloidal mill, under the high-speed rotation of the motor, the material directly enters the high-shear crushing zone from the inlet. Through a special crushing device, it rapidly breaks down large particles, agglomerates, and lumps in the fluid, then it is drawn into the shearing crushing zone. In the extremely narrow working channel, intense friction and grinding occur due to the high-speed cutting of the rotor blades against the stator blades. Under the action of mechanical movement and centrifugal force, the finely crushed material is re-pressed into the fine grinding zone for further grinding and crushing. The fine grinding zone is divided into three levels, with increasing blade precision, decreasing pitch, and longer linear velocity as it extends outward, resulting in finer material with each grind. Simultaneously, the fluid gradually curves outward radially. At each level, the fluid's direction and speed change instantaneously, subjected to millions of high-speed shearing, intense friction, compression grinding, and particle粉碎. After millions of high-speed shearing and grinding in three fine grinding zones, the material achieves the effects of liquid molecule chain breakage, particle crushing, and liquid-particle tearing, resulting in complete dispersion, crushing, emulsification, homogenization, and refinement. The fineness of the liquid material can reach 0.5 μm, and the normal conveying height can be up to 3-6 meters.

Note: The user provides parameters related to material characteristics, or brings the material to the production base for on-site testing. The manufacturer selects the internal structure of the grinding disk based on the medium characteristics.
