1. Working principle

The colloid mill is driven by the motor through the belt to drive the rotor (or rotor) and the matching stator (or stator) to rotate at a relatively high speed. The processed material is pressurized by its own weight or external pressure (which can be produced by the pump) to produce the rural spiral impact force. Through the gap between the stator and the rotor (the gap can be adjusted), the strong shear force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force, friction force High frequency vibration and other physical effects can effectively emulsify, disperse and crush the materials, so as to achieve the effect of superfine grinding and emulsification.  

2. Main features

Compared with the pressure homogenizer, colloid mill is a kind of centrifugal equipment, which has the advantages of simple structure, convenient maintenance and maintenance, and is suitable for high viscosity materials and large particle materials. Its main disadvantages are also determined by its structure. first. Due to centrifugal movement, the flow rate is not constant. For materials with different viscosity, the flow rate varies greatly. For example, when processing viscous paint materials and thin milk fluid, the flow rate can be more than 10 times different. Secondly, due to the high-speed friction between the stator and the material, it is easy to generate large heat, which makes the processed material denatured; thirdly, the surface is easy to wear, and the refining effect will be significantly reduced after wear
