- Semi-Autogenous Grinding (SAG) is a type of grinding applied when fine crushing could cause severe problems or when ore is variable in hardness or competency1. SAG mills are similar to autogenous mills but use grinding media like a ball mill grinder2. They take material itself as the main grinding media and grind through their mutual collision2.
