Semi autogenous grinding (SAG) mills, because of their advantages in terms of capital and operating costs, were the natural choice for mines as their primary grinding mill option. Then, in the late 1980s when the price of copper rose quickly from a low of /lb to a high of /lb, this substantial increase in price further fuelled the
Semiautogenous mills or SAG mills, as they are often called, can accomplish the same size reduction work as two or three stages of crushing and screening. Often used in grinding at modern mineral processing plants, SAG mills reduce the material directly to the desired final size or prepare it for the following grinding stages.
SemiAutogenous Grinding (SAG) mills are the technology of choice for reducing primary hardrock ore to feed size for use in a secondary crusher. In these mills, cascading ore undergoes impact breakage against grinding balls in a rotating cylindrical shell.
Semiautogenous grinding uses a minimal ball charge in the range of 615% 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.

For the mining industry, our semiautogenous (SAG) grinding mill uses a minimal ball charge in the range of 615 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media.
