A survey of grinding circuit control methods: from ...

Abstract A conventional grinding circuit consisting of one open-loop rod mill and one closed-loop ball mill is essentially a two-input= twooutput system, assuming that the classifier pump box level is controlled by a local loop. The inputs are the ore and water feed rates and the outputs are the product fineness and the circulating load.

Simplified Hybrid Semi-autogenous Grinding Mill Control ...

Semi-autogenous grinding (SAG) mill control optimisation presents a number of challenges. SAG mills have multiple inputs that are used to control multiple outputs (MIMO process). Secondly, the SAG mill loading process is a 'high inertia' process that can be approximated as an integrating process. This means that it is open-loop unstable.
