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, i.e. pH = 7.0 and pH = 8.5, while keeping other parameters fixed, at a mill speed of 74 rpm for 1 hr.
One reason is the dry in-bed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here. Within these test works, mill parameters like grinding pressure, separator speed and dam ring height were varied, following a factorial design of the experiments.
A considerable amount of test work has been carried out by WEIR Minerals covering dry grinding flow sheets, and further test work is in progress.
