Improving Coal Pulverizer Performance and Reliability
type coal pulverizer. In this design the grinding rolls are stationary, while the ring (or bowl, as it is sometimes called) is rotated by a worm gear drive. Powerful springs force the grinding rolls against the ring, providing the pressure required to pulverize the coal. Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw
