Based on batch grinding method and normalization idea, a conical ball mill is used and a quantitative separation method of grinding characteristics of multicomponent complex ore is proposed. The results show that the feed sizes of polymetallic complex ore have an obvious influence on the particle size distribution of intermediate grinding products in the early stage of grinding.
