  • Rod Millan overview ScienceDirect Topics

    As such when the product is sticky rod mills are preferred over ball mills. 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.
