2.3 Pulverizer Designs and Pulverized Coal Handling. Coal preparation predated pulverized coal firing, particularly for stoker units where sizing has always been very important, particularly in the minimizing of fines. Predating the development of pulverized coal firing came the development of pulverizers used in the processing of minerals.

The coal blocks are crushed and ground into powder in this chamber. While grinding the coal, the pulverized coal is taken out of the coal mill from the discharge device by a special induced draft fan. The coarser coal granules will return to the grinding chamber through the return screw of the discharge device for regrinding.
