A guide to SAG Mill management - Mipac
2024/5/17 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.

Understanding the SAG Mill in Copper Ore Mining Process
The Autogenous Mill, also known as AG Mill, is a type of grinding mill used in the mining industry. This machine uses ore and rock itself as grinding media to perform its job. Unlike other types of mills that use steel balls or rods for grinding materials, the Autogenous Mill relies on the material being ground to break itself into smaller pieces.
