Semi-Autogenous ??????? (SAG) Mills
SAG mills are large, rotating cylindrical vessels partially filled with ore and a small proportion of steel grinding media (balls). The ore itself acts as grinding media, hence the term “semi-autogenous.” The grinding mechanism involves impact, attrition, and abrasion as the mill rotates, tumbling the ore and balls to reduce particle size.
