PDF SAG Mill Optimization using Model Predictive Control - ANDRITZ

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, M.S., van der Westhuizen, A.P., & Mainza, A.N. 2009).

SAGDesign Test | Starkey and Associates Inc.

The calculated cumulative mill revolutions to 80% passing 1.7 mm is used together with the mass of the SAG mill charge to compute the SAG mill specific pinion energy, as seen below. The process to determine the revolutions is done in cycles, with the -1.7 mm material (fines) removed from the mill after each cycle up to 60% passing 1.7 mm.

What's the Difference Between SAG Mill and Ball Mill

AG/SAG is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the grinding media, through the mutual impact and grinding action to gradually reduce the material size.
