| Popis: | The main regularities in the conversion of the mineral matter of coals of different ranks—brown coal from the Kansk-Achinsk Basin and hard coal from the Ekibastuz Basin—upon their crushing in mills with different energy intensities were established. The grinding of brown coals in a disintegrator led to a more uniform distribution of mineral substances in size fractions and to an enrichment of the fine fraction in internal ash components and iron-containing minerals, as compared with crushing in a ball–tube mill. The grinding of Ekibastuz coal in a disintegrator did not lead to significant changes in the distributions of mineral components in size fractions and in terms of density, as compared with crushing in a ball–tube mill. |
