Multi-Component AG/SAG mill model structure. According to the preliminary modelling findings the breakage rates for each component vary according to their proportion in the Multi-Component AG/SAG mill model structure. According to the preliminary modelling findings the breakage rates for each component vary according to their proportion in the mill fresh feed. The reason behind this variation is that different feed blends result in different compositions in the mill charge which act as grinding media.
