The mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.
Pebble mills have the advantage of being self-contained, which helps keep operators from being exposed to the milled product. Pebble mills can be used equally well for either wet or dry grinding. In the case of wet grinding the particles are also being dispersed in the liquid medium.
