Ball mill

With particular reference to mill size, it is apparent that a change in diameter in a large mill is relatively far less significant than the same change in diameter for a small one For example, using well established relationships between power draw and mill diameter and speed, 50 mm (2 inches) of liner wear results in about 14 percent power increase (at constant loading and rotational speed.
