kiln iron–ore pellet induration process PDF Free Download

A Dynamic Mathematical Model of the Complete Grate/Kiln Iron-Ore Pellet Induration Process J.A. THURLBY Induration (drying and hardening) of iron ore pellets is an energy-intensive feed preparation step for both the blast furnace and direct reduction routes to iron. It is commonly carded out by a 'grate/kiln' process.
