of the Bond ball mill grindability test. For all model based methods, a reliable method to calculate mill power draw for a given mill is required for the calculation of power draw. Morrell (1996) proposed a mathematical model for autogenous, semiautogenous and ball mills which is based on the motion of grinding charge inside the mill.

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