Apr 04, 2014· Methods of assessing coal strength are compared on the basis of a literature review. The Hardgrove grindability index (HGI) is the most expedient. There is a close relation between HGI and the coal quality, as well as the power consumed in grinding. Accordingly, the HGI values of coal samples may be used to optimize the crushing of coal as a preliminary to coke production.Crushing properties of coal Request PDF,To assess the mechanical properties of coal, it is best to determine their Hardgrove grindability HGI, as shown in.
