Ball Mill an overview | ScienceDirect Topics

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 cyclonesThe ball mills are operated at a ball charge volume of 30–32% and 785% critical speed The SAG mill trommel undersize is combined with the ball mills’ discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directedGrinding Mills an overview | ScienceDirect Topics
