types of coal pulveriser

Pieces of coal are crushed between balls or cylindrical rollers that move between two tracks or “races” The raw coal is then fed into the pulverizer along with air heated to about 330°C 650°F from the boiler As the coal gets crushed by the rolling action the hot air dries it and blows the usable fine coal powder out to be used as fuel
