(75 100 mm) diameters. Ball mill balls experience a greater number of impacts, but at lower magnitude than SAG mill balls, due to the smaller ball size, and smaller mill diameter. Feeds are typically highly abrasive, contributing 10 15 µm/hr wear for softer ores and 20 µm/hr for abrasive gold, copper
