The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls.
Colloid mill is a machine used in the disintegration of solid particles or droplet size of a liquid present in suspension or emulsion. The machine consists of an inlet (which is subjected to a tremendous shearing action that effects a time dispersion of uniform size) and an outlet. Colloid mill works on the rotorstator principle.
