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 ...
