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.

The ball mill as a means of investigating the mechanical. The charge of a ball mill is the percentage of the mill interior filled with the grinding media, including the voids between the media and the batch charge. It has been suggested that optimum efficiency can be achieved when the ball mill is 60-70% full" but others" have
With the large‐scale development of the ball mill, the direct‐drive gearless ball mill has emerged, eliminating the limitation of the transmission torque of large gear. However, it is difficultto process, transport, install and maintain the gearless ball mill because of its vast volume, and the coils cannot be decoupled freely.
