The 30 mm ball draws slightly more power as J increases from 11 to 16% but the gain in capacity is much more. In fact for an increase in J from 11 to 16% (i.e. 45% increase), power draw increase is 31%, while capacity increases by 51%. For the 50 mm balls the respective increase in power and capacity is 28% and 42%.

In a real operation of coal pulvirizer, its capacity does not change linearly with coal HGI values [13]. For instance, with a change of feed coal HGI from 90 to 80, the decrease in mill capacity is minor; however, much greater decrease may be registered when HGI change from 50 to 40. This is one of the major demerits of HGI.

The coal mill is assumed to be a lumped parameter object, and a calculation method based on the static heat balance of the coal mill calculates all heat input into or output from the coal mill quantitatively; however, a model of the coal mill has yet to be established on this basis (Feng et al., 1997, Ganapathy (2002), Magdalinović (1989)).
