Grinding Power efficiencies are achieved by filling of charge and smaller steel media (balls) used for fine grinding. Typically, stirred media mills use 25mm make-up balls, where conventional ball mills are using much larger grinding media. The popularity of stirred media mills has risen in recent times.

Stirred Media Mills Grinding Energy -

The use of finer media also results in reduced energy input probably due to increased ” fluidity”. These results agree with those reported by Orumwense and Forssberg [1992] for dolomite samples ground in an annular ball mill. Effect of media density. The effect of media density on the grinding of limestone is shown in Table 2.
