The general shape of the selection function is shown in Fig. 2 which depicts the particle selectivity for breakage reaching a maximum value at a certain particle size, i.e., x m.This implies that the particles coarser than x m are not broken efficiently in the mill. Therefore, x m can be a useful indicator to prepare the feed for the mill; hence the mill efficiency can be improved.
