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 ).
