The attrition product will have a distribution similar to the usual ball and pebble mill products. It will amount to 20 – 50% of the combined mill product depending upon grinding conditions. The steady-state abrasion rate for like surfaces under autogenous grinding conditions will mainly depend upon following factors:

The grinding tests were performed in a vertical stirred-ball mill MA01D manufactured by Mitsui Mining (Japan). Fig. 1 illustrates the schematics of a laboratory-scale batch type of the attrition mill. The mill consists of a stationary stainless steel chamber holding a centrally positioned rotating stirrer system with a five-arm impeller fitted to the stirrer shaft.

Milling in an attrition mill (Fig. 24) is effected by the stirring action of an agitator that has a vertical rotating shaft with horizontal arms. This motion causes a differential movement between the balls and the material being milled, thus providing a substantially higher degree of surface contact than is achieved in tumbler or vibratory mills..
