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 The steel rod mill working principle is different from the ball mill machine which is mainly reflected in the contact mode of the grinding media When the rod mill operation is start the steel rod in the barrel body is thrown up with the barrel body The steel rods are in linear contact with each other
