Ball Mill Parameter Selection & Calculation

The development of all-steel media allowed maximum grinding effect in these mills, but the rate of wear of these media was very high, often around 1 kg per tonne of material ground. Although hard alloys were available, they tended to be brittle, and hard media would break into irregular pieces, causing a rapid reduction in grinding efficiency.Figure 8.2 Media motion in the tumbling mill. 8.1 Grinding 8.1.1 Grinding action Liners protect the outer shell of the mill from wear - liners are renewable. 2.
