Ball Mill. Ball mills can operate in either wet or dry conditions. They are advantageous because they can achieve a very fine particle product size (refer to Table 1). 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.
