### Ball Charge and Grinding EfficiencyGrinding

· Ball size will also affect the grind P80. Efficiency is in part determined by the Axb value of the ore. A small lab mill can give guidance on the influence of ore strength and ball size. Larger balls will increase P80 in ball mill thereby reducing overgrinding.
