A mill is a machine that is used to break down solid materials into smaller pieces by cutting, grinding, or crushing. The process of milling includes the use of force that acts on a material to tear it apart and reduce its size. Milling improves the performance of ingredients, and the products made from them.

Ball mills are the most common grinding machine employed in the mining industry. Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semiautogenous grinding (SAG) mill followed by a ball mill (two stage circuit).

A ball mill is a type of grinder used to grind or 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.

Tumbling mills (ball mills, rod mills, etc.) utilize both continuouspressure and impact mechanisms. Blasting, explosive shattering, and decrepitation (firesetting) are tensiontype crushing operations; all three are relatively unimportant as crushing operations, although blasting is, of course, preeminently useful in rock excavation.

Autogenous or autogenic mills are socalled due to the selfgrinding of the ore: a rotating drum throws larger rocks of ore in a cascading motion which causes impact breakage of larger rocks and compressive grinding of finer particles. It is similar in operation to a SAG mill as described below but does not use steel balls in the mill.
