Ball Mill - an overview | ScienceDirect Topics

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 dry basis is typically 75 vol.-% ore and 25% steel. The is operated in closed circuit with a particle-size measurement device and size-control cyclones.
