Coal Grinding

Coal Grinding. To achieve good combustion and satisfactory flame formation, coal needs to be dried and ground to a proper degree of dryness and fineness. Drying of moisture in coal is achieved normally by ducting part of the kiln exhaust gas through the mill with inlet temperatures of up to 300°C. Inert kiln exhaust gases with oxygen contentThe US Coal Industry in the Nineteenth CenturyThe coal industry was a major foundation for American industrialization in the nineteenth century.
