The Rod Mill is the same as the Ball Mill in the construction and available to both of wet and dry processing. Unlike the Ball Mill, however, the Rod Mill uses rods instead of balls as the grinding medium. As a result, its uses are different from those with the Ball Mill. In other words, the Rod Mill gives impact on and grinds coarse particles.
Rods may be used to reduce large size particles in one mill (Rougher) and feed ball charged secondary mill for fine grinding to -1 micron. The Model 624 is the Laboratory Size mill. It is 6 inches in diameter by 24 inches long, with a 1 hp 230- 460 3 ph 50-60 Hz motor.
