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.

The breakage rate function shape of the SAG mill is largely governed by the mill load particle size distribution and mill speed. The feed in the mill contains fractions of ore that serves as the grinding media. Larger ore fractions break the smaller particles but also breakdown themselves and exit the mill as a product.

Hammer mill, ball mill, air-jet mill, pin-mill, and conical screen mill are the commonly used equipment for the milling operation. In these, impact, attrition, and shear compression are the main forces for the size reduction. The selection of the appropriate equipment is mainly based on the desired particle size of the product.
