SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
The ball mill is used for grinding materials such as coal, pigments, and feldspar for pottery. Grinding can be carried out either wet or dry but the former is performed at low speed. Blending of explosives is an example of an application for rubber balls.
Roll crushers crush material between two rolls or between a single roll and a fixed, flat plane. Grinding mills serve a wide variety of industries. In gristmills, for example, grinding mills are used to grind grains. Ball mills are commonly used to crush coal in power plants and to make black powder for pyrotechnics.
