SAG Mill

SAG Mill Comminution (SMC) Test®. The SMC Test® is conducted on a single size range which is typically mm + mm, hence the sample requirements are less than drop weight test. The test generates the Drop Weight Index (DWI) which is expressed in KWh/m 3, which strongly correlates to values generated from a Drop Weight Test.

SAG Mill Optimization using Model Predictive Control

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, 2022). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity.
