Advantages of pellets 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

NOx formation in iron ore rotary kilns

Iron ore pellets are often produced using the so-called Grate-Kiln process which is designed to oxidize the magnetite (Fe3O4) to hematite (Fe2O3) and to sinter the pellets so they can be used in steel manufacturing The heat required for this process comes from the combustion of a pulverized fuel in a rotary kiln involving the formation of a jet flame To oxidize the pellets large amounts
