Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.% ore and 25% steel. The ball mill is operated in closed circuit with a particlesize measurement device and sizecontrol cyclones.
