· When used with grinding media (“balls”) they are called SAG (semi-autogenous grinding) and when only rock is present they are called AG (autogenous grinding) mills. The most common secondary mill is a ball mill in which relatively fine feed particles (0.1–10.0 mm top size) are ground in a charge consisting predominantly of steel
