Autogenous and Semi-Autogenous Mills FLSmidth

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 the mill. Via the use of sophisticated instruments ...
