· Autogenous grinding (AG) and semiautogenous grinding (SAG) mills use the material to be ground as the grinding media. Autogenous grinding mills use larger rocks to impact and break smaller rocks as the mill rotates. Semiautogenous mills are basically the same autogenous mills, but with the addition of balls, similar to those in ball mills.
In recognition of ore variability, many current SAG mills are installed with variable speed drives, capable of operating the mill through a wide and continuous range of speed values. Mill speed and liner profile determine grinding media trajectories, as shown in Figure 1. By increasing mill speed or the steepness of liner attack angle,

SAG mills are essentially autogenous mills, but utilize grinding balls to aid in grinding large rocks like in a ball mill. SAG mill is generally used as a primary or first stage grinding solution. It is widely used in the gold, copper and platinum industries but also in the lead, zinc, silver, and nickel industries.
researching the grinding media egory used in its SAG mill. Recent market developments rendered this egory suitable for potential cost savings. A SAG mill is predominantly used during the preliminary stage of grinding in the mining process. The machine grinds large chunks of material to small, useable pieces for processing.
Control of SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell,, van der Westhuizen,, Mainza, 2009).
