Milling | Biomass / Coal

The coal mill is a key ancillary to any pulverized fuel boiler. It grinds the coal to a fine powder so that it can be burned with maximum efficiency. Biomass also moves through hammer mills, dryers and pulverizers during the production process. Avoiding mill explosions is essential for personnel safety and asset protection.
