b) Feed Preparation – With more widespread use of coarse ball milling it is increasingly important to present a suitable feed material topsize to the ball mill. Significant inefficiencies are introduced as a result of the need for larger (and, as a result, fewer) grinding balls. Furthermore, as mill performance is related to the complete size distribution of the feed material.
