What's the Difference Between Ball Mills and Rod Mills

The rod mill adopts overflow type and open type discharge, does not use grate type discharge. The diameter of the rod mill discharge end is larger than that of the same size ball mill. When the rod mill speed is lower than the working speed of the same size ball mill, the medium in the rod mill is in a sloping working state.

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

Rod mills, how they function Mine Engineer.Com

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. Rod
