Based on the motion of the milling media (balls), the ball mill can be classified into three zones: (i) shearing zone, where the balls are lifted due to the rotated vial action and frictional forces, (ii) cataracting zone, where the balls are falling due to the gravity, and (iii) inactive zone, where the balls are not moving (Figure 3.8).

Drive at Center of Gravity (DCG) With the Synchronous Dual Ball Screw Feeding System used in a Milling-Turning compound machining center as the research object.
With a batch mill, as previously suggested, the centre of gravity of the ball charge and powder charge sensibly coincide and so the density correction (1 + 0.4σ/q) previously deduced is applicable. In the grate mill the powder surface probably slopes from the inlet end of the mill to the discharge end in the manner indicated in Figs. 1.4b and 1.4d.

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.
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight.
