The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at 1.4 to 1.6. Rod mills accept feed up to about 50 mm (2 in.) and produce a product in the size range of 3000 to 270 mm (–4 to –35 mesh).

The diameter of the discharge trunnion is larger than that of the feed trunnion giving an easy material flow through the mill. The discharge trunnion can be furnished with a trommel screen to remove rod fragments, wooden chips etc. from the mill discharge. Rod Mill with End Peripheral Discharge: Used when a moderately coarse product is desired.

Mill Type Overview. Three types of mill design are common. The Overflow Discharge mill is best suited for fine grinding to 75 – 106 microns.; The Diaphram or Grate Discharge mill keeps coarse particles within the mill for additional grinding and typically used for grinds to 150 – 250 microns.; The Center-Periphery Discharge mill has feed reporting from both ends and the product …

Wire Rods and Wire Rod Mills. Steel wire rods are an all-round talent since they are the key product of steel industry with multiple uses. They are used as the material for fasteners, springs, bearings, wire ropes, chains, cables, wire meshes, wire fencings, tyre cord, reinforcement in railway sleepers, and many other uses.

This is partly due to the bridging action of the rods over the coarse particles avoiding the fine sizes (the grinding kinetics aspect), and partly due to the nature of material flow through the mill with its rod load (the material transport aspect). This article will stress mainly on the nature of material transport within the rod mill.

Ball Mills vs Rod Mills. Rods in place weigh approximately 400 pounds per cu. ft. and balls in place approximately 300 pounds per cu. ft.. Thus, quantitatively, less material can progress through the voids in the rod mill grinding media than in the ball mill. get price

In Mineral Processing Design and Operations (Second Edition), 2016. 8.3.1 Rod Mill Charge. Rod mill charges usually occupy about 45% of the internal volume of the mill. A closely packed charge of single sized rods will have a porosity of 9.3%. With a mixed charge of small and large diameter rods, the porosity of a static load could be reduced even further.
