• Difference between Rod mill and Ball mill
There are various ratios of the length and diameter of the ball mill, such as those below 2, about 3, and above 4. In addition, the rotating speed of the barrel of the rod mill is lower than the working speed of the ball mill of the same specifiion, so that the medium in the rod mill .

• Rod mills, how they function
Rod mills operate at lower speed than ball mills since the rods are rolled and not cascaded. For an equivalent grind, a rod mill uses less steel than a ball mill because of the lower speed and better contact between the media and ore. The rod charge must be maintained in good working condition, and broken and worn rods must be removed.
