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.
