2016-1-1  Some dry autogenous mills operating in Canada are 8.5 m in diameter and 1.5 m in length. These are known as Aerofall mills. The Cadia Hill (Australia) wet SAG mill is 12.2 m in diameter with a 20 MW motor and in 2004 was the largest diameter mill in operation in the world.

Autogenous and Semi-Autogenous Mills

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
