Size reduction occurs through a primary crusher followed by semi-autogenous grinding (SAG). Large rocks are screened from the overflow and are sent through a pebble crusher, which recirculates the ore back to the SAG mill. The smaller material after SAG milling is classified by hydrocycloning.Autogenous and Semi-Autogenous Mills Fruitful,Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. SAG and AG Mills operate by lifting ore/grinding media and dropping it on the operating bed of the mill charge. High impacts from lifting ore and media promote impact breakage which is the primary mechanism for size reduction in
