Aug 01, 2000  By optimizing the size of the grinding media, the mill capacity can be increased in many grinding operations. In this specific case, grinding with a −20-mm ball charge required 26% less grinding energy than grinding with a −30-mm ball charge. The energy savings can, in most cases, be converted to an increase in capacity.
