A new autogenous and semi-autogenous mill

In the case of autogenous (AG) and semi-autogenous (SAG) mills this has provided a significant challenge to modellers, due in part to the interaction between feed characteristics and mill performance and also due to the difficulty in obtaining high quality relevant data from full-scale circuits. As a result the literature contains numerous papers on AG/SAG mill modelling, the majority of which

SAG mills (semi-autogenous grinding mills) -

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.

Mill (grinding) - Wikipedia

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.
