RingRoll (BowlMill) and BallRace Mills comprise most coal pulverizers currently in service at pulverized coal power plants. The grinding rolls are stationary in this design, while a worm gear drive rotates the ring (commonly known as the bowl). Powerful springs force the grinding rolls against the ring, providing the pressure required to ...
