SAG Mill Power Model - Grinding & Classification Circuits ...

Prediction of correct sag mill power consumption with a change in ore hardness, solid percent (density) to the sag feed, rpm of sag and PSD has always been very tricky. So far, I have used Austin-Morrell model and Hogg- Fuerstenau power model, but these models seem to work well only under certain boundary conditions.
