Likewise, Hebbar (2011) has studied the grinding wear behaviour of austempered ductile iron as media material in the comminution of Kudremukh haematite iron ore in a ball mill. The grinding experiments were conducted under different pH conditions, pH = and pH =, while keeping other parameters fixed, at a mill speed of 74 rpm for 1 hr.

This type of breakage is the final in the transformation chain of rotational energy of the ball mill into ball charge movement (Fig. 1). The charge profile shows three zones that are typical for the action: • The grinding zone where ball layers sliding over one another grind the material trapped between them. •

Promising results obtained from cement industry encouraged the test studies on mineral grinding. van Drunick et al. (2010) presented VRM pilot plant test results where zinc ore was ground. In his study it was concluded that the total specific energy of the AG/SAGball mill circuit, which was kWh/t, was reduced to kWh/t by using VRM.
