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.

Kick assumed that the energy required to reduce a material in size was directly proportional to the size reduction ratio dL/L. This implies that n in eqn. (11.1) is equal to -1. If K = K K f c where K K is called Kick''s constant and f c is called the crushing strength of the material, we have: dE/dL = -K K f c L 1 which, on integration gives: E

Intermediate autogenous grinding can efficiently replace the rod mill and ball mill stage of a conventional grinding circuit. The need was shown for closed circuit operation of the last stage of crushing to control the top size of the mill feed. A reasonable rate ratio between media and total mill feed was established.
