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 particle-size measurement device and size-control cyclones.

2009-8-27 Water addition at Cyclone 1 is used to control particle sizeof the overflow stream of this circuit. In essence this onlydetermines the mass cut to overflow and underflow. With afiner particle size in the overflow, there is thus less materialin the overflow. This implies more material in the under-flow, which is the fresh feed to the second ball mill. If circulating load in the second ball mill is kept constant,any
