Grindability

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). HGI is computed by measuring the undersize of the product. Coals with higher HGI are easy to grind (Speight, 1994).
