What's the Difference Between Ball Mills and Rod Mills

19/11/2019· Compared with the ball mill, the rod mill adopts advanced controllable feeding and discharging technology, and can use the appropriate grinding body according to the grinding material. The point contact of the traditional ball mill can be changed into line contact, which can make the discharge granularity more uniform and the output is higher. The rod mill is mainly used for gravity

Ball Mills vs Rod Mills

When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length. New feed entering at one end of the mill causes the rod charge to spread at that end. This produces a series of wedge shaped slots tapering toward the discharge end. The tumbling and rolling rods expend most of their crushing force on the

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. Rod mills usually require greater operator attention. It is important that the rods stay essentially parallel to one another. If rods become misaligned
