The colloid mill consists of stainless steel mill or semi stainless steel materials mill, the basic working principle is that the fluid or semi fluid materials undertake strong cutting force, friction force and high speed vibration through the relative high speed movement between the rotor and stator which make the materials crushed, emulsifying, homogenizing, temperature, so as to obtain satisfactory fine grinding products. Character: it includes Vertical type of horizontal type. The main machine consists of body shell, stator, rotor, adjustment system, cooling system and motor. The main parts are all made of stainless steel, with corrosion resistant and non-toxic. The users choose different specification of colloid mill on the basis of different textures of materials, production efficiency and usages, to get a good result.
