Comparation With Rod Mill And Ball Mill
ball mill and rod mill Choice of materials used in grinding media are significant.Many factors are involved in the selection of grinding media.

Grinding balls should be made of forged steel, or cast steel having the same resistance to breakage. Rods should be hot rolled, hot sawed or sheared with standard tolerances and machine straightened.

Rods will be consumed at a rate ranging from 0.2 lb/ st on soft, easily ground material up to 2 lb. per st on harder material. Steel consumption of balls is spread out over an even greater range. An indication as to the consumption of balls is spread out over an even greater range. And indication as to the consumption of media can be obtained from power consumed in grinding. Balls or rods will often wear at a rate of about 1 lb for each 6 or 7 kwh consumed per st of ore. Liner consumption is generally about 10%-15% of the media consumption. A significant portion of the metal wear in grinding can be attributed to corrosion. Dry grinding metal consumption is appreciably less than that of wet grinding partly because corrosion is minimize. However, the material ground dry is typically softer and less abrasive than wet a true comparison.
