· · Rod Mill – Ball Mill Most of the rod mill – ball mill circuit controls in the Iron Ore Industry are patterned after a scheme developed by Erie Mining Company. This control is based upon the premise that constant volume, and structure of feed to the cyclone will result in a controlled sizing of the cyclone overflow by varying the density of the cyclone feed.

Ball mills are filled up to 40% with steel balls (with 30–80 mm diameter), which effectively grind the ore. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture.

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.
