rod mill and ball mill

Rod mills have an industrial yield that is less than that of a ball mill, which explains the fact that balls have a much larger grinding surface than rods. The power needed to operate a rod mill could exceed 30% of the power used in a ball mill. When they are worn, rods must not stretch but break in rather small pieces, so that they can exit the mill.

Ball Mill Brief Introduction
