Dec 13, 2011 · A higher Hardgrove index indicates the coal is easier to grind. 50 HGI normally is taken for calculating the base capacity of the mill. When coal with HGI higher than 50 is fed to the pulverizer, the output will be higher than base capacity, and below 50 HGI, the output will be lower. The total moisture in coal has a high effect on mill output.
Furthermore, high-moisture, low–heating value coals result in higher fuel and flue gas flow rates, higher auxiliary power use, higher net unit heat rate, and higher mill, coal pipe, and burner ...

Hard coal is a sedimentary rock which was formed by deposition and carbonization of plant remains. It is hard and resistant. More than 50% of its weight is made up by carbon. Therefore it is classified as high-rank coal. Other fossil fuels like sub-bituminous coals with high moisture contents as well as brown coal and lignite are lower ranked.

observer estimates the coal moisture content. 2. THE COAL MILL The work presented in this paper, is based on a Babcock MPS 212 coal mill used at Elsam's Nordjyllandsværktet Unit 3. However, the method proposed in the paper is so generic that it can be applied to other types of coal mills. The coal mill is illustrated in principles in Fig. 1.
capability of the mill system in meeting both requirements when grinding high moisture coals is clearly evident. However, the overall system performance does not define the specific action of the crusher-dryers which insures satisfactory operation of the mill system with extremely high-moisture coals.
