Model Predictive Control - Rockwell Automation

Mills can be open or closed circuit. In open circuit, the ore passes through the mill once and on to a classifier which separates fine and oversize material, the former going to a product stream and the latter to a secondary mill. In a closed circuit the discharge flows from the mill to a sump and is pumped to hydrocyclones.
