As ball filling in the SAG mill is quite low additional grinding media would likely increase the processing capacity of the SAG mill however the capacity of the ball mill with installed power for the required product size of 170 181 m has reached its limit...

Bond Work Index

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...
