In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace. The coal is feed into the coal mill through a central inlet pipe where gravity is used to lead the coal to the bottom of the mill, where the grinding table and some heavy rollers pulverizes the coal to particles.
The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal fired units.
