Autogenous Grinding - Mining Fundamentals

Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or ...

SAG Mill | Autogenous and Semi-Autogenous Mills | FL

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 ...

Semi-autogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diameter-to-length ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ball-milling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
