Mining comminution – crusher, ball mill, and advanced ...


Not surprisingly, comminution is a huge expense. After all, we're crushing rocks here. Interestingly enough, the crushing isn't always the most expensive part of crushing. Crushing machinery, particularly the SAG mill is massive, and much of the expense of running the mill comes from powering the movement of this giant mass of steel.

Comminution - an overview | ScienceDirect Topics


This is obtained for a comminution device using Eq. (5.4), by measuring W (the specific energy being used, kWh t −1), F 80 and P 80 and solving for Wi as the operating work index, Wi O. (Note that the value of W is the power applied to the pinion shaft of the mill. Motor input power thus has to be converted to power at the mill pinion shaft output by applying corrections for electrical and ...
