SAG mill power draw models are used in mill design and grinding circuit modeling to predict how much power will be consumed by a particular mill geometry and operating configuration. This paper will compare sAG mill models by Morrell, Loveday (using ‘Power Numbers’ published by Barratt) and Austin against several published mill surveys.get price

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.get price
