The advantages of colloid mill, compared with pressure homogenizer, colloid mill is a centrifugal equipment first, its advantages are simple structure, easy maintenance of equipment, suitable for materials with higher viscosity and larger particles. Its main disadvantage is also determined by its structure. Due to the centrifugal movement, the flow rate is not constant, and the flow rate varies greatly for materials with different viscosities. For example, the same equipment, when processing viscous paint materials and thin milk fluids, the flow rate can differ by more than 10 times; secondly, due to the high-speed friction between the stator and the material, it is easy to generate greater heat. Denature the processed material; third, the surface is easier to wear, and after wear, the refining effect will be significantly reduced.

Colloid mill is composed of stainless steel and semi-stainless steel colloid mill. The basic principle is between fixed teeth and moving teeth connected relatively at high speed. In addition to the motor and some parts of the colloid mill products, all the parts in contact with the material are made of high strength stainless steel. In particular, the key dynamic and static grinding plate is strengthened. Therefore, it has good corrosion resistance and wear resistance, so that the processed materials are pollution-free and pure.

Stainless steel colloid mill belongs to the crushing equipment, but the crushing effect is relatively fine, and it can be applied to materials with higher viscosity and larger particles, so this equipment is mostly used for production and processing of jam, jujube paste, bean paste, bone paste and meat paste in the food industry.
