The mills are partially filled with steel grinding balls or rods, commonly referred to as 'grinding media'. Mills need to be refilled continuously with new grinding balls as old ones wear out. ... SAG Mills: 4"-6" forged-steel balls are recommended. Cast balls are not agood choice. Their outer crust is hard (typical Brinell hardness > 450).

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.
