説明

The authors used 10 coal samples, which were vitrinite rich and of different coal rank (carbon content were from 70.0 % to 87.4 %), and the relation between maceral compositions in vitrinite group and grindability indicated by the Hardgrove grinding index (HGI) was elucidated.<BR>Brittleness of the coal structure rather than its hardness dominates coal grindability. The brittleness of collinite and the collinite content have a specific relation with HGI and coal rank. Higher rank coal includes a higher collinite content, and the collinite becomes increasingly brittle with increasing coal rank and collinite content; in the results, the HGI of the coal samples becomes higher.After grinding coal samples by a Hardgrove grinding tester, the collinite content in the fraction of -75μm increases with higher HGI. These results show selective grinding of collinite and indicate that only collinite in vitrinite group has a strong influence on coal grindability.
