Grindability - an overview | ScienceDirect Topics

There are several methods to estimate the grindability of coals. One of the most commonly used methods is the Hardgrove Grindability Index (HGI). HGI for coal is determined by grinding 50 g of sample in a ball and ring type mill for 60 revolutions, after which the product is sieved through a 200 mesh sieve (75 micron screen) ( Speight, 1994 ).
