The HGI provides an approximation of the behavior of coal in utility boilers, with the estimated pulverizer mill capacity based directly on HGI. According to Fitton et al. (1957) and that reported in Hower (2008), a 53 HGI coal requires 2.5 times the number of revolutions as a 110 HGI coal to produce a fineness such that 80% of the product can pass a 200 mesh (75 μm) screen.
