SAG mill at Cadia (described by Dunne et al., 2001) is shown in Figure 3. Any time a process line (green) touches or exceeds the corresponding motor limit (the red or blue lines), the motor is at risk of tripping due to high current, depending on the conditions. Safe operating of a mill and motor means that

Detecting the onset of overloading in a semi-autogenous grinding (SAG) mill is a challenging task for operators to perform due to the complex and nonlinear nature of an overload. To detect an overload, operators must simultaneously monitor the correlations between several measurements of the SAG process.

SAG mill. 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.

The SAG mill's steel liners were failing to meet the required service life. To remedy the problem, the supplier had added more material to the liner design. But this created its own challenges, reducing the effective grinding volume and adding weight to the mill that was pushing bearing pressures dangerously close to limitations.

SAG mill is usually used to grind large pieces into small pieces, especially for the pre-processing of grinding circuits, thus also known as primary stage grinding machine. Based on the high throughput and coarse grind, AG mills produce coarse grinds often classify mill discharge with screens and trommel.

In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al.[19,20] found a scale-up factor for the Isamill of exactly 1, while Gao et al. imply that the scale-up factor for SMDs is 1.25.
