    13/02/2017 · Over a period of many years various fine grinding machines have been developed and used, ... it is customary to crush from 1/2″ to as fine as 8 mesh. Many grinding circuits necessitate regrinding of concentrates or middling products to extremely fine sizes to liberate the closely associated minerals from each other. In these cases, the feed to the ball mill may be from 10 to 100 mesh or .

  • Grindability

    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 .
