Inferential measurement of SAG mill parameters

Jun 01, 2001SAG mill discharge is screened with the oversize recycling via a gyratory cone crusher, while the undersize is diluted with water and fed to the primary cyclones for classification. Primary cyclone underflow is split between a small recycle stream to the SAG mill feed chute and a ball mill feed stream.

SAG Mill Optimization using Model Predictive Control

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).
