Based on his work, this formula can be derived forball diameter sizingand selection: Dm <= 6 (log dk) * d^0.5 where D m = the diameter of thesingle-sized ballsinmm.d = the diameter of the largest chunks of ore in themillfeed in mm.
[email protected]2) Ball milling – a ball mill with a diameter of2.44 meters, inside new liners, grinding wet in open circuit. When the grinding conditions differ from these specified conditions, efficiency factors (Rowland and Kjos, 1978) have to be used in conjunction with equation 1.
The balls are initially5–10 cm diameterbut gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically75 vol.-% ore and 25% steel. The ball mill is operated in closed circuit with a particle-size measurement device and size-control cyclones.

The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed toball mills(dry basis) is typically 75 vol.-% ore and 25% steel.

The mill with30 cmin diameter and30 cmin length and the test conditions are standardized with a maximum ball size of40 mmand an ore top size of3.35 mm. With less than 300 balls it poses no challenge in running the simulations if only grinding media are included.
