The density of three important raw materials viz. the ore, the coke and the limestone are quite different. The heaviest is iron ore with around 5-6 glcc, the lightest is coke with density of around 15 glcc and the limestone is intermediate with-a value of density around 30-35 glcc. It means that the rolling tendency of coke particles is
