Grinding mills are size reductions machines that often follow crushers in the processes where finer products are desired after crushing. Different grinding machines are usually named as mills, for example rod mills, ball mills, and attrition mills. Because of the name, verb milling is also been used as a synonym for grinding.

Compared with SAG mill grinding, autogenous grinding using feed prepared to include coarse, competent rock and crushed finer rock resulted in a 14% reduction in grinding energy expressed as kWh/t and no steel balls were required as additional grinding media. The coarse rock amounted to about 20% of the mill feed.

Autogenous (AG) and Semi-Autogenous (SAG) milling has seen increased use in recent years, especially in large mineral processing operations. These mills typically have a large diameter relative to their length, typically in the ratio or 2 or 2.5 to 1. AG mills employ ore as the grinding media. However, one the challenges with AG mills is that ...
