There is a wedge-shaped device or gasket adjustment device between the two rolls and on the top of the wedge-shaped device placed an adjusting bolt. When the adjusting bolt pulls up the wedge, the wedge will move the movable roll from the fixed roll, so the gap between the two rolls become large, and the discharging granularity will get big.Ring-Roll (Bowl-Mill) and Ball-Race 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 ...

The vertical pre-grinding mill makes use of pressing force and shearing force for material grinding. It offers better grinding results than roller mills.
