RingRoll and BallRace Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a RingRoll Mill the rolls may rotate while the ring is stationary). RingRoll (BowlMill) and BallRace Mills comprise the majority of coal
A mathematical model was developed for a ballandrace mill based on specific rates of breakage and primary fragment distributions. The model includes internal classification of particles falling back into the race and external classification due to the builton classifier.

Jun 19, 2015· The only assumptions required for determination of the single ball trajectory are a coefficient of friction between the ball and mill lining, and unobstructed free fall .
Jul 07, 2017· In ball and race mill the coal passes between the rotating elements again and again until it is pulverized to the desired degree of fineness. The coal is crushed between two moving surfaces namely balls and races. A worm and gear drove the upper stationary race, and the lower rotating race holds the balls between them.
Ball Race Mill Get constant throughput of pulverized coal with capacities from 10 to 40 metric tons/hour. Lowmaintenance design a) Higher available grinding mass. b) Arrangement is such that most of the coal particles gets ground by rubbing of coal with coal particles instead of coal to metal contact.
