2018-2-1 · It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.

Grinding Mills

Raw coal is fed to pulverizer from the coal feeder via a center feed pipe. The coal is grounded between the three grinding rollers and the rotating table in the pulverizer. Pulverized coal is simultaneously dried by the drying gas fed from bottom part of pulverizer and carried into the separator fixed at the top of pulverizer.
