Coal mill pulverizer in thermal power plants. Nov 17, 2012 2.Coal pulverizer mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill. The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill.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. The powdered coal from the pulverizer is directly blown to a burner in the boiler.
