Autogenous and Semi-Autogenous Mills - ScienceDirect

01/01/2016  These are known as semi-autogenous grinding (SAG) mills. In the mining industry all of these types of mills are in use. The disintegration and size reduction of ores in AG/SAG mills is brought about by a combination of impact, attrition and abrasion forces during mill rotation. Particles at the toe of the mill charge receive the maximum impact forces from falling rocks and other grinding media ...

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 ...
