The Function Of a Colloid Mill Machine and How To Use It
The basic working principle of the colloid mill is that the fluid or semi-fluid materials undergo strong cutting force, friction force, and high-speed vibration through the relatively high-speed movement between the rotor and stator, which causes the materials to be crushed, emulsified, homogenised, and temperature, to obtain satisfactory results. It …

DE-11: Lesson 43. SIZE REDUCTION
The principle of attrition mills is that the material is rubbed between two surfaces. Both pressure and frictional forces are generated. The extent to which either of these forces predominates depends on the pressure with which both surfaces are held together and the difference in the speed of rotation of the surfaces.

What Is a Ball Mill and How Does It Work?
A ball mill and a tumbling mill are both types of grinding mills used to reduce material size. We mainly use a ball mill for mixing and grinding processes. In contrast, we generally use a tumbling mill for finer material reduction. What are the balls? Ball mills grind materials into an extremely fine form.
