The ability to simulate the Bond work index test also allows examination of truncated ball mill feed size distributions on the work index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure ), a question arises as to whether this practice will alter the ball mill work index (BW i) of the material ...

For a typical 7mlong mill, the power required is therefore predicted to be MW. This is consistent with a peak motor power rating of MW that would commonly be used for a mill of this size. Field data is very difficult to obtain for comparison with the DEM results so we instead compare with some of laboratory observations.
