Bond Work Index - an overview | ScienceDirect Topics

An alternative approach to determine the effect of closing screen size on the Bond ball mill work index (BW i), in the absence of extensive test work, is to use computer simulation. The batch grinding process has been modelled using the size–mass balance approach (Austin [37], Chapter 11 ) and if we can do this, then we can effectively simulate the Bond ball mill work index test.
