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 particle-size measurement device and size-control cyclones.

Design aspects of large ball mills. - Free Online Library

The design of ball mill drives is, in many ways, more difficult than for AG and SAG units. This stems from the fact that the ball mill is generally smaller in diameter, so that the notional tangential force at the shell is higher for a given power input (although this effect is somewhat offset by the ball mill's higher rotational speed).
