The first measures relative amounts of energy needed to pulverize different coals by finding the number of ball-mill revolutions needed to grind a sample so 80% passes a 200- mesh sieve (74 microns). The ball-mill grindability index, in percent, is found by dividing number of revolutions into 50,000

The mill may operate either in closed circuit with a separator or be used for pregrinding in a ball mill circuit. The Horomill is approximately one third the length of the equivalent ball mill and, when standing alone, power savings of 30-50% are claimed. The overall performance of a milling circuit is best summarised by its specific power
