Coal Pulverizer - Pall

2021-8-6  Mechanically pulverizing coal into a fine powder enables it to be burned like a gas, thus allowing more efficient combustion. Transported by an air or an air/gas mixture, pulverized coal can be introduced directly into the boiler for combustion. There are several pieces of equipment involved in processing coal to be burned in this fashion.
