Indentation of bituminous coals: Fracture, crushing and

28-08-2020· The energy spent for crushing of a unit volume of the core Π was calculated and used to estimate the average m and the maximum R m sizes of the coal dust in coals of varying stages of metamorphism. Our results show that in all cases there are no particles that are greater than the upper limit for crushed dust particles, however there are nanodust particles.
