Coal Mill Pulverizer. A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the steam-generating furnaces of fossil fuel power plants. Material
Coal is pulverized in the coal mill to a very fine particle size. The coal and primary air are then introduced to the coal nozzle. Swirled air, coupled with the burner throat’s flow-shaping contour, enables recirculation patterns that extend into the furnace.
