bonds work index ball mill details specification

The ability to simulate theBond work indextest also allows examination of truncatedball millfeed size distributions on thework index. For grinding circuits where the feed to aball millis sent directly to the classifier and the cyclone underflow feeds theball mill(see Figure 3.10), a question arises as to whether this practice will alter theball mill work index(BW i) of the material ...
