Grinding Balls & Rods - Mineral Processing & Metallurgy
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.

momentum to the mill (with a resultant loss in power). As the mill speed nears 100 per cent of critical speed, centrifug-ing of the outer layer of the medium starts, resulting in a loss in the active mass of the load and a reduction in the effective mill diameter, both of which contribute substantially to loss of power.
