History. The SAG mill model by proposed by Leonard Austin 1990 was largely based on modifications of earlier tumbling mill models by Hogg Fuerstenau and F. Bond. The model uses a kinetic potential energy balance to describe the power draw of a mill charge. Many geometric components of the earlier models were fit to empirical relationships measured by Austin.

Mill relining is the most specialised maintenance task in a mineral concentrator. Almost invariably the AG SAG and Ball mill liner lives dictate the shut down dates of the concentrator. The replacement of the mill liners determines the length of each concentrator shut down. In other words the liner lives and their replacement define the time
