SAG Mill Control Instability: Causes and Solutions CEEC

The paper is illustrated by trend plots taken from a SAG mill in a major gold mine. The paper goes on to explain the practical causes of the instability ranging from inappropriate type 2 control strategies to poor control loop tuning and to inappropriate operator intervention caused by lack of operator training.

build up over time. For AG/SAG mills, this may result in a critical size build-up and associated throughput losses. The importance of steady-state testing increases with the ore heterogeneity. On the other hand, the batch tests (e.g. Mod Bond, SPI®, SMC Test®) generally require less sample, which make them more suitable candidates for variability
