There are a number of SAG mills in operation around the world with diameters reaching up to 40 ft. These operations continually invest in new technologies to improve their energy efficiency and capacity in their SAG circuit. Commercial SAG mill performance is determined by a large number of variables, both mine-site variables and mill variables.
Model Predictive Control for SAG Milling in Minerals Processing Steven J. McGarel, Rockwell Automation Introduction SAG and ball mills are generally accepted as the largest power consumers in a mining and mineral processing operation and can be 80% of total electrical energy consumed at a specific power consumption of around 20kWh/ton.

Semi-autogenous 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.
The ore is ground into a fine powder by large rotating mills. The two types used in the Mission South Mill are called SAG (semi-autogenous grinding) mills and ball mills. SAG mills use larger pieces of ore to break up the smaller pieces (autogenous — does it by itself). The larger pieces break down as well.
With the development of the world's largest SAG mill, Ø40'x29', Outotec responds to the need by offering increased efficiency, effective grinding conditions and improved mill capacity up to 15% with reduced energy consumption. Outotec has recently been awarded a contract to deliver one of the largest grinding mills in the world.
and ball mills, have almost become obsolete in the move to higher milling rates required to process lower metal grades. Grinding circuits with fully autogenous (AG) or semi-autogenous (SAG) mills, often combined with ball mills are now the standard to meet the high capacity requirement for processing ores with lower metal grades.
The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.
Acoustic emissions monitoring of SAG mill performa. Abstract Particle grinding is a final stage in the minution process used to liberate minerals from gangue in mineral processing plants Semiautogenous grinding SAG occurs in tumbling mills which use both large ore particles and steel balls for grinding Grinding is the most energy intensive mineral processing unit operation and hence its ...
and a standard Bond Ball Mill Work Index test (BWi) on SAG ground ore. The SAG test reproduces commercial SAG mill grinding conditions on 4.5 L of ore and determines the SAG mill pinion energy needed to grind ore from 80% passing 152 mm to 80% passing 1.7 mm, herein referred to as macro ore .
SAG is an acronym for semi-autogenous grinding. SAG mills are autogenous mills that also 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.
