The investigation has demonstrated that the grinding capacity of a mill is maintained when balls are replaced by pebbles, up to about 30% of the charge volume. The energy dissipation and the surface area for grinding are reduced as the pebble volume increases, and it reasonable to assume that the pebble wear compensates for these changes.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them.
