Austin SAG model

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.
