q is the charge volume in fraction of mill volume (40 % = 0.40) nc is the mill speed in fraction of critical speed; Li and Di are length and diameter inside shell lining respectively (in meters) For a mill with more than 2.1 m (7′) diameter the total power is obtained by dividing net power by 0.85. The graph is based on 40% charge volume.

Further calculations of water volume in the gas involved calculation of the dry fraction or percentage of water in the gas stream. To make this calculation, the water vapor fraction when the gas is saturated with water vapor is needed. This value is determined using saturation tables and for 152 degrees F, the saturated fraction is 0.267 or 26.7%.

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 …
