PDF Semiautogenous grinding (SAG) mill liner design and development
Semiautogenous grinding mills (SAG mills) are tumbling mills that most commonly have a shell diametertolength ratio of around two. With this high aspect ratio, SAG mills generate both thrown and cascading ballmilling actions with shell linings shaped to lift and to throw alloy steel grinding balls of up to 150 mm (6 in.) in diameter. These
Mill (grinding) Wikipedia
SAG mill. SAG is an acronym for semiautogenous 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' () in diameter, powered by a 28 MW (38,000 HP) motor.
Semi Autogenous Grinding Mill an overview ScienceDirect
In a SAG mill the dimensions of the mill were m × m and the specific gravities of the mineral and that of the balls charged were and respectively.. The mill was rotated at 75% of its critical speed when 8 % of the mill volume was charged with grinding :1. The mill power drawn, 2. The maximum mill filling possible.

What's the Difference Between SAG Mill and Ball Mill
The working principle of the selfgrinding machine is basically the same as the ball mill, the biggest difference is that the sag grinding machine uses the crushed material inside the cylinder as the grinding medium, the material constantly impacts and grinding to gradually pulverize.
https://Difference Between Sag Mill vs Ball Mill Mech4study
Working: SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.
Ball Mill vs SAG Mill: What's the Difference?
The operating principle difference between a ball mill and a SAG mill is their specific energy consumption. Ball mills use an induced storage mechanism to grind materials. The materials are ground using impact and the friction created between the particles as they rotate in a chamber.
