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). Grinding action is by line contact between the rods extending the length of the mill. Rods tumble and spin in roughly parallel alignment simulating a series of roll crushers. This results in preferential grinding of ...

Ball Mill Introduction . There are three main stages to mineral processing in the mining industry.These are: Comminution (crushing and grinding).; Beneficiation (separation and concentration).; Smelting and refining.; Ball mills are employed in the comminution stage as grinding machines (size reduction).The purpose of grinders in the mining industry is to …

Use the krebs model to select the proper size and number of cyclones for a rod mill / ball mill assuming that pressure drop is 6 0 Kpa The feed flowrate is 2 5 0. 0 t h solids, and contains no moisture. The rod mill specification requires a product of 5 5 % solids by volume, and the ball mill requires 4 5 % solids by volume.
The original charge to a mill is generally between 40% and 50% of mill volume for ball mills and 35% to 45% mill volume for rod mills. As a general figure rod mills will have a void space within the charge of around 20% to 22% for new rods. In ball mills the theoretical void space is around 42% to 43%.
Rod mills are widely applied in cement industry, chemical industry, new building materials, fire-resistant materials, fertilizer, porcelain and glass industry etc. Rod mill crushes generally coarser than those produced in Ball mills, and rod mills are well suited to handle coarser feed and to control the bigger size of the product.
When calculating rod mill power for a rod mill-ball mill circuit, do not allow for improvement in the ball mill performance due to receiving rod mill feed. If the rod …
Question: Select the proper size and number of cyclones for a rod mill/ball mill circuit where new feed to the rod mill is 250 metric tons per hour (MTPH) solids. Both mill discharges join together at cyclone feed sump and are pumped to cyclones. Overflow is to be XY % - 200 mesh (74 microns) at a minimum of 40% solids by weight.
There are three mill slurry characteristics which you should note. The % fines in the rod mill feed. For the purposes of rod mill performance analysis, "fines" can be arbitrarily defined as particles finer than 75 microns (200 mesh). Rod mill feeds which contain less than approximately 10% fines are good candidates for fines addition testwork.

Center Periphery Discharging Rod Mill. The center periphery discharging rod mill feeds the material through the journals at both ends of the mill, and discharges the grinding products through the circular orifice in the middle of the cylinder (Fig. 3).Ore pulp is characterized by short stroke, steep slope, and it can be coarsely ground with fewer fine …
Bond would say ideal feed is 80% -16mm for a 13 W.I> material. If the Material has a higher W.I. there is a Bond formula to calculate the ideal feed size for a normal 1.5 to 1.8 L/D ratio rod mill.
Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 35-48 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations. Under wet grin…
The characteristics of the rod mill are that the product is relatively rough. Still, the particle size is uniform, containing less coarse sand and sludge, and the over-grinding is lighter. The discharge particle size is usually between 0.833~0.147mm, and the particle size characteristics of the rod mill product differ from those of the rod mill.
