Rod mill, not a ball mill
The likely mode of failure with a rod mill is a tangle, at which point you have to throw the rods away and buy new. An old employer had several rod mills and frequently part of the plant was stopped while they changed all the rods after a tangle. A tangle causes bent rods and bent rods cause the next tangle.

are approximately half those in a ball mill grinding load. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approxi-mately 300 pounds per cu. ft.. Thus, quantita-tively, less material can progress through the voids in the rod mill grinding media than in the ball mill, and the path of the material is more confined.

Ball & Rod Mill Density
Rod mill grinding efficiencies have been shown to increase in the range of 5 to 15% with more dilute discharge slurry (i.e., increased feed water) at least down to the range of 45 to 50% solids by volume. The higher the discharge % solids in the plant rod mill, the better the candidate for feed water addition rate test work.

Ball Mill (Ball Mills Explained)
Ball mills with a drum length to diameter ratio greater than 1.5 are referred to as tube mills. Ball mills may be primary or secondary grinders. Primary grinders are fed from crushers such as a jaw crusher. Secondary grinders are fed from other grinders e.g. a rod mill. Ball mills are usually either of the grate (diaphragm) or overflow type.
