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.

"Coarsening" of ball mill is an abnormal phenomenon that the fineness of grinding products is significantly coarser and difficult to control. It generally occurs in double bin open circuit tube mill with small length diameter ratio. Coarsening of the ball mill will increase the energy consumption of the ball mill, cause waste, and large particle size will also affect the subsequent sorting.
