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.
Get PriceProcessing industries are mostly of the tumbling mill type. these mills exist in a variety of types rod, ball, pebble autogenous and semiautogenous. the grinding action is induced by relative motion between the particles of media

There is a definite difference in the grinding performance between a ball mill and a rod mill. the rod mill has a higher impact force than a ball mill. this makes the rod mill better suited to grinding courser or harder ore. in contrast the ball mill is more effective in producing a finer grind. in most mines, where there is more than one mill ...
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.

Ball mills mineral processing amp metallurgy. working principle amp operation. the apparent difference in capacities between grinding mills listed as being the same size is due to the fact that there is no uniform method of designating the size of a mill, for example a 5 x 5 ball mill has a working diameter of 5 inside the liners and has 20 per cent more capacity than all other ball ...
Rod mill products are generally coarser than those produced in a ball mill. because of these characteristics, the rod mill has also found wide acceptance by manufacturers of fine concrete aggregates, where rigid state or federal specifications must be met. rod mills are also used extensively in the grinding of chemicals, coke, limestone, slag, etc.
