Email: pradeebhamit@gmail, npappa@rediffmail, [email protected]. Abstract: The paper presents development and validation of coal mill model (including the action of classifier) to be used for improved coal mill control. The model is developed by using the mass and heat balance equations of the coal mill.

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. Rotating throat for coal pulverizer - Sure, Alloy Steel.
D-20 had coal separation efficiencies of 54.8% and 97.0% for coal particles smaller than 90 μm and 1000 μm, respectively, and the coal flow rate was 11.7 kg/s (Table 5, Table 6). Another consideration of this design was to capture large particles that bounce with an angle from the curved portion of the classifier.

The ball mill is a traditional coal pulverizer machine, which has been widely used since it was invented. In the cement plant, the new dry process cement manufacturing requires the moisture content of coal powder to be 0.5% ~ 1.5%, while that of raw coal is 1.5% ~ 4.0%. Therefore, the ball mill should have a drying function besides grinding.
