The AG mill (autogenous grinding mill) is a medium-free grinding machine. In order to improve the processing capacity, 2% -3% steel balls can be added (also known as semi autogenous grinding mill or SAG mill). Raw ore or coarse crushed ore from the mine can be directly fed into the AG mill (SAG mill) for grinding.
