    Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small. Table 2 outlines some typical ball diameters found in ball mills dependent on the staging or purpose of the mill. Table 1 - Ball mill feed and product sizes (Callow
