How Pulverizer Work. Pulverizers process materials in batches or continuously by accepting incoming material, often on a conveyor, rotating it and pressing a crushing into it, then sending it out. They may also cool, heat, or aerate material as it exits. For the convenience of the user, pulverizers can crush materials to varying levels of ...

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.
