Grindability an overview ScienceDirect Topics

For biomass, one should use (Agus and Waters, 1971; Joshi, 1979 Agus and Waters, 1971 Joshi, 1979) a standard volume of sample instead of mass to compare the grinding ease to coal and torrefied biomass. Thus an equivalent HGI was used to define the grinding ease of torrefied biomass. More details are given in Bridgeman et al., (2010).
