the endemic issue of ball mill overload in sabc circuits

Maintaining the work balance between the primary SAG mill and secondary ball mill(s) is an overlooked bottleneck, and thus opportunity, in an increasing number of circuits worldwide. As circuit capacities are expanded by releasingthe SAG mill bottleneck, the work is progressively passed on to the downstream ball mills
