The grinding balls used in semi-autogenous mills must be of top quality so that they will not break from the impact forces encountered in primary semi-autogenous mills. Pilot plant testing for primary autogenous or semi-autogenous grinding gives the following information needed for selection of mills, circuit design, and mill design.

SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.

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.

The feed size for these mills is limited to the maximum size that can be practically conveyed and introduced into the large mill feed chutes. And the product of the large AG/SAG grinding is either a finished size ready of processing, or an immediate size for further grinding in a ball mill, pebble mill, or a VERTIMILL® or a stirred media detritor (SMD).

Does a SAG Mill reduce steel consumption? Do SAG mills cost less to operate compared to conventional rod or ball mill grinding circuits? Mining companies are always searching for new ways to cut costs. In order to be competitive and justify the tremendous capital costs of new projects, there has been a strong trend toward mills with a capacity of 36,300 or more tonnes per day (40,000 stpd).

Grinding is easily enabled in autogenous mills by attrition. Also, autogenous mills have grate discharges, so as to retain the coarse grinding media in the mill while dispatching the fine particles. The other benefits of using autogenous grinding include – reduction of metal wear, and elimination of secondary and tertiary crushing steps.

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
