A Comparison of Three Types of Coal Pulverizers

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. coal is fed through a centrally located feed pipe to the center of the grinding table.

Coal grinding technology: a manual for process engineers ...

Then the coal undergoes pulverization which reduces the top size to 1/8'' and/or grinding which reduces the top size to 1 mm or less. This handbook examines the intermediate and fine grinding of coal. Four coal grinding devices - three dry one wet - are discussed with the appropriate ancillary equipment for complete systems.
