SAG Mill Optimization using Model Predictive Control

Semi-Autogenous Grinding mills can be optimized for maximum ore throughput or maximum grinding energy efficiency. In both cases, precise control of the mill weight is critical. Model predictive control provides an additional tool to improve the control of Semi-Autogenous Grinding mills and is often able to reduce process variability beyond the best performance that can be obtained with proportional-integral-derivative or expert system control methods. Model predictive control is able to optimize the control of processes that exhibit an integrating type response in combination with transport delays or variable interaction, which are characteristic of the Semi-Autogenous Grinding mill

Override and Model Predictive Control of Particle Size and

A new grinding control strategy based on override control (ORC) and model predictive control (MPC) is presented to control product particle size and feed rate in grinding process. ORC is employed to avoid mill overloading and to optimize fresh ore feed rate. MPC is adopted for its outstanding features in dealing with large time delay and the constraints imposed on process variables.
