Throughput and product quality control for a grinding mill

Throughput and product quality control for a grinding mill

A non-linear model-based control architecture for a single-stage grinding mill circuit closed with a hydrocyclone is proposed. The control architecture aims to achieve independent control of circuit throughput and product quality and consists of a non-linear model predictive controller for grinding mill circuit control and a dynamic inversion controller to control the fast sump dynamics.
