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 carried out by a 'grate/kiln' process. A mathematical model of the process is described, in which mechanistic models of the grate furnace, kiln, and cooler are linked …
Introduction to Iron ore Pellets and Pelletizing processes
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 …
