The rod mill operates at lowspeed relative to the ball mill since the rods are rolled and not cascaded. However, one main disadvantage of the rod mill is that it needs significant operation attention because the rods must be parallel to one another to obtain a high crushing efficiency, otherwise the grinding action will be lost.
