55 known as the distribution function [45, 46]) describes the distribution of fragment sizes obtained after a breakage of particles of size, b1j, b2j, ., bnj are the mass fractions of particles in size classes 1, 2, ., n after a breakage of particles in size class j. The mechanism of breakage is illustrated in [23] by a diagram shown in Fig. 3.

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.
