For overflow ball mills the charge should not exceed 45 of the mill volume . For grate discharge mills the charge should occupy about 50 of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge He and the radius of the mill R i.e.

Rod Mill An Overview Sciencedirect Topics

Rod mills are used in an open circuit between crushing and the ball mill. They often operate in wet and where the pulp contains up to 50 solid by mass. This machine is equally very applicable to dry where it could take a feed that has achieved 6 moisture. As such when the product is sticky rod mills are preferred over ball mills.
