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 3.10, a question arises as to whether this practice will alter the ball mill work index BW i of the material ...
SAG mill power includes a correction for the interstitial mill filling. In the case of the estimated ball mill power, the power was calculated using the Bond methodology. Table 4 shows the principle parameters obtained. The 25th percentile throughput rate corresponds to the 75th percentile Axb value.
