The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.

Mineral grinding circuits can be controlled with a set of proportional-integral (PI) controllers or alternatively by specialized controllers which make use of optimal control theory.
