Improving Coal Pulverizer Performance and Reliability

2017-4-3  Figure 3 shows a cut-away of a Ring-Rolltype coal pulverizer. In this design the grindingrolls are stationary, while the ring (or bowl,as it is sometimes called) is rotated by aworm gear drive. Powerful springs force thegrinding rolls against the ring, providing thepressure required to pulverize the coal.
