Iron Ore Pelletization: Part I. Fundamentals Taylor Francis Online

The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the interparticle bonding within the pellet.

The amount of these additives added are 5% of the mass of the iron ore. The mixture is mixed thoroughly inside a ball mill and transferred to a pelletizing machine. Once in the pelletizing machine, a level of moisture of approximately 9% is introduced by spraying water into the mixture. This will result in the formation of iron ore pellets.

Major DRI production processes are either natural gas based or coal based. Feed material for the DR process is either sized iron ore of size ranging from 10 mm to 30 mm or iron ore pellets of size ranging from 8 mm to 20 mm produced in an iron ore pellet plant. The gas based process uses a shaft furnace for the reduction reaction.

Then the iron ore pellets will sent through metallic conveyor into the furnace to undergo heating process at 1200 degrees. After the heating process, the heated base mix will converted into a semi liquid cake. Using a sinter breaker machine the cake is break into small pellets. Finally these iron ore pellets under goes cooling in the cooling tower.
