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.

Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 3045%). Pulp (crushed ore and water) fills another 15% of the drum's volume so that the total volume of the drum is 50% charged.

Based on our studies, we favor freeze crushing in a frozen ball mill apparatus, such as the Mikrodismembrator (S. B. Braun International). Freeze crushing involves shaking the frozen sample in a capped cryotube with a frozen steel ball. The containment in a cryotube during this phase reduces the risk of sample loss and the risk of contamination.
