These mills typically grind ROM ore in a single stage. A large example of such a mill was converted from a singlestage milling application to a semi autogenous ballmillcrushing circuit, and the application is well described. This refers to highaspect AG/SAG mills. Ball Charge Motion inside a SAG Mill. With a higher density mill charge.

Crushers are used to reduce particle size enough so that the material can be processed into finer particles in a grinder. A typical processing line at a mine might consist of a crusher followed by a SAG mill followed by a ball mill. In this context, the SAG mill and ball mill are considered grinders rather than crushers.

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.

Crushers do the heavy work of breaking large pieces of solids into smaller lumps. Primary crushers are run on materials out of mine the size of which may reach more than one meter and breaking it into 150 300 mm lumps. A secondary crusher reduces those lumps to particles in the size range of 5 10 mm. Grinders reduce crushed feed to powder.
