A guide to SAG Mill management

A SAG (Semi-Autogenous Grinding) mill is a giant rotating cylinder filled with grinding media and the ore being reduced. As the mill rotates, the grinding media lifts and the impact crushes the feed material. SAG mill control refers to the practice of managing the mill load, which is the amount of material inside the mill at any given time.
