Blends of biomass on coal have dramatic and deleterious impacts on the grinding properties of the blend. Petroleum coke tends to have relatively low HGI values and behaves, with coal in blends, as the harder material. The handling ability of coal blends has been given scant attention in the literature.

A longtime issue with Alaskan coal has been its low Hardgrove Grindability Index (HGI) number (around 32 2). HGI is an indicator of ease of grinding with lower numbers indicating lower grinding throughput. Power plant operators prefer coal with high HGI numbers so that coal grinding does not become a bottleneck.

HGI values. Durite (dull coal) is a lithotype characteristic by low HGI and is generally the toughest (Temeeva, 1979). Labelling fusite as lithotype with the highest HGI value is disputable, because its extreme fragility is caused by origination of significant amount of fine fractions rather during screening that in the course of
