The vast majority of coal mill designs are based upon a 50 to 55 HGI design point. However, grindability is a complex issue and such factors as coal moisture content, required fineness (high volatile coals can require a coarser grind) along with the milling and burner systems are all factors in assessing coal grindability. Generally, a value of ...

The moisture content has a direct influence on the bulk density of the coal blend, as shown in fig.7. There is a minimum bulk density at a moisture con-tent of around 8% to 9% for a grain size range from 0mm to 10mm. Figure 7: Bulk density in relation to the water content of coal [6] From fig.8 it is obvious that the bulk density of the

It may be noticed that for moisture content of 1% and 10%, the calculated values of the factor are 0.5 and 22.2, respectively. So only 0.5 will be added with the constant 93.25 of the equation compared to 22.3 for the latter. Such increase obviously indicates that increase in moisture content makes the coal softer if it is considered alone.
