Many mills utilize a grinding wheel which breaks material into smaller parts as it moves against the workpiece, which can also move ground material from the grinding surfaces to a collection area. Some major types of mills used for industrial grinding include ball mills, vibratory mills, and rod mills.

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.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
