Whether you operate a ball mill, sag mill or any other type of mill, you know the importance of keeping the mill running. Unplanned down time because of equipment breakdown is frustrating, costly… and something you want to avoid at all costs. The thing is, many breakdowns could have been avoided.
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.
