The size of 30 mm was optimum for raw materials of −0.45 + 0.15 mm and −0.15 mm. The optimal ball size distribution was 12 mm (40%), 20 mm (40%), 32 mm (10%), and 40 mm (10%) for dry fine-grinding of calcite ore. Finer ball loads were unable to break coarser particles nipped in the feed.

Pintaude et al. (2001) have considered the effect of particle size on the abrasive wear of high-chromium white cast iron mill balls. They have concluded that the ratio of steel ball to particle size is the critical factor. The highest ball wear rates occurred during grinding of fine granite under dry (120 mg/cycle) and wet (129 mg/cycle) conditions
