Crushing properties of coal. December 2014; Coke and Chemistry 56(12):449-455; DOI: 10.3103/S1068364X13120090. Authors: Denis Miroshnichenko.

Crushing properties of coal Coke and Chemistry

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.
