Grinding Balls. Steel balls ranging from ¾ to 5 in. in diameter are used. Rods range from 1½ to 4 in. in diameter and should be 3 to 4 in. shorter than the inside mill length. Tube mills are usually fed balls smaller than 2 in., whereas 4- or 5-in. balls are more commonly used for ball-mill grinding.

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.
