The colloid mill is driven by a motor through a belt drive to drive the rotating tooth (or rotor) and the matching fixed tooth (or stator) to rotate at a relatively high speed. The processed material is increased by its own weight or external pressure (produced by a pump). The pressure produces downward spiral impact force. Through the gap between the fixed and rotating teeth (the gap is adjustable), the material is effectively emulsified and dispersed by the strong shearing force, friction force, high-frequency vibration and other physical effects. And crushing to achieve superfine crushing and emulsification of materials.
From the principle point of view, liquid mixing pot manufacturers have grinding and smashing effects. The refining effect of colloid mills is generally weaker than that of emulsifiers, but it has strong adaptability to materials (such as high viscosity, large particles), so it is In many cases, it is used in the front of a homogenizer or in high viscosity applications. Colloid mills are often used for refinement when there are more solid substances.
