An assessment of grindability index of coal ScienceDirect

2002-4-20  Abstract. Grindability index of coal is an important technological parameter to understand the behaviour and assess the relative hardness of coals of varying ranks and grades during comminution. This is usually determined by Hardgrove Grindability Index (HGI), which involves requirement of a costly grinding equipment and accessories not readily
