CONTRIBUTION TO DETERMINATION OF COAL …

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

Screening and Grading of Moist Fine Coal

Screening and classification of moist fine coal is a difficulty in screening technology research at home and abroad. As moist fine coal binds to each other, material adheres to the screen surface and blocks the screen hole, thus reducing the effective screening area and screening efficiency. And the viscous materials are not loose and stratified, making the screening process more difficult.
