Rod Mill with Density High Productivity High

Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the 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). Grinding ball density have impact on the ball mill, in general,same size ball, density high productivity high, density small productivity small.

Grinding steel ball hardness too high is not good for the ball mill, the first cause is the grinding steel ball rebound severe, part of energy loss in the rebound, therefore,energy is not used for ball crushing,so affect the crusher;the second, grinding steel ball hardness too high, ball and ball contact sliding severe, weakened the grinding effective. For with the roller press of closed circuit ball mill, this value can be adjusted for 12 m2/t, and the liner plate is continuous ascension type. The balls in the specific surface area should be 35-38 m2/t, belt roller pressure unit for 38-40 m2/t. The ratio of specific various balls diameter still according to the maximum stacking density calculation.

The mining ball mill is widely used in powder-making production line including cement, new-type building material, silicate, refractory material, fertilizer, ore dressing of ferrous metal and non-ferrous metal, glass ceramics, etc. Ball mill can be divided into tabular type and flowing type according to different extracting way of mine. With effective surface area of steel balls to measure the rationality of the steel ball ratio. A warehouse in effective surface area of steel balls should achieve every ton of steel balls 9.5-10.5 m2.
