  • 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.

    the mill discharge from ball mill 1 will increase. With the same water addition to sump 1 the particle size of Cyclone 1 overflow will increase. This will decrease the ratio and hence the control loop will add more water to keep the ratio constant. However the amount of slurry reporting as fresh feed to the second milling circuit will increase.
