Mining Industry: What is a coal mill? - Quora

Coal mill is used to grind, pulverize and dry coal before the coal is transmitted the boiler. The coal is feed into the coal mill via a inlet pipe so that the roller coal mill such as ball mill or vertical mill can pulverize the coal into particles.Effects of Mill Performance on Unburnt Carbon in Coal,,Two separate mills, referred to as Mill 20 and Mill 40 in this paper, supply pulverized coal to the four PC pipes (and burners) for each elevation. The four PC pipes are located at the four corners of the boiler, and are referred to as corners 10, 20, 30, and 40 in this study (ref. Fig. 3).Steam For Power and Process - Babcock & Wilcox,B&W's radiant boiler designs accommodate pulverized coal, including difficult-to-burn coals, natural gas and/or oil and combustible byproduct gases. Subcritical pressures range usually 1800 to 2600 psi (12.4 to 17.9 MPa) and superheater and reheater outlet temperatures as required, usually in the range of 1000 to 1050 F (538 to 566C).
