Introduction to Iron ore Pellets and Pelletizing processes

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 Normally pellets are reduced considerably faster than sinter...
