Davis and Orban (1995), in a study of low and high volatile bituminous coals, attributed the segregation to both rank (and inherent HGI) differences and to the grinding behavior of the maceral assemblages, independent of coal rank. Mill power consumption in blends tends to follow the power consumption for the harder coal (Conroy et al., 1989).
