Mining comminution – crusher, ball mill, and advanced a...
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 - SlideShare
Comminution in the mineral processing plant takes place in a sequence of crushing and grinding processes. Crushing reduces the particle size of run-of-mine ore to such a level that grinding mill can further grind it until the mineral and gangue is substantially produced as separate particles. Crushing is accomplished by compression of the ore ...
