Virtually all modern raw mills incorporate closed circuits with classifi- cation in a cyclone or mechanical separator and return of coarse mater- ial for regrinding (Figure 3). Ball mill operation is described in more detail under finish milling (Section 5.2). Roller mills have a lower specific power consumption than ball mills.

Predictive Maintenance - an overview | ScienceDirect Topics
The normal outage, before predictive maintenance techniques were implemented in the plant, to completely rebuild the ball mill was three weeks and the repair cost averaged $300,000. The addition of predictive maintenance techniques as an outage-scheduling tool reduced the outage to five days and resulted in a total savings of $200,000.

Another argument for the usage of beater mills over ball mills is the low number of collisions with sufficient energy to cause breakage that occurs in the later, as presented in (Powell and McBride, 2006). The operational basis of a beater mill is a spinning flywheel with beaters mounted around it, which induces a high-speed turbulent gas flow.
