One commonly used method for assessing grindability is the Hardgrove test, which consists of grinding a specially prepared coal sample in a laboratory mill of standard design. The percent by weight of the coal that passes through a 200mesh sieve (a screen with openings of 74 micrometres, or inch) is used to calculate the Hardgrove grindability index (HGI).

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.
