Overall, pebble crushing can increase throughput as well as decreasing the total power required to grind to a given size. Typically, pebble crushing also coarsens ball-mill circuit feed, a consideration if a ball-mill circuit is already taxed. The definition of critically sized material is often misunderstood.

The media charged to a pebble mill should be between 50% to 55% of the mill volume. The desirable characteristics of such grinding media are that they should be tough, hard, heavy, and resistant to any chemical action, with the material to be ground. Pebble consumption generally averages 2# per ton with a wide variation of between ½# to 9# per ton.
