Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. [1] [2] In geology , it occurs naturally during faulting in the upper part of the Earth's crust . [3]

Comminution efficiency is a technical term that relates some measure of the output from a comminution machine to the energy input into it. The term has usually been encompassed in controversial arguments.

The purpose of the study was to investigate the relationship between comminution and amorphisation of α-lactose monohydrate particles during ball milling under different milling conditions, including ball-to-powder mass ratio, milling time and ball diameter.

A ball mill is a type of grinder used to grind and blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics and selective laser sintering. It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell.
