A process for producing fired pellets by granulating finely-ground iron ore and subjecting the resulting granules sequentially to drying, dehydration, preheating, and firing, wherein said process comprises adding an additive to said finely-ground iron ore at the time of granulation, said additive reacting with iron ore to form a compound which has a melting point lower than the preheating ...
Pellets are primarily used in blast furnaces and are also used in DR-plants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material) are known collectively as the "burden".
In addition to mined iron ore, other sources of iron, such as flue dust collected from blast furnaces, or the dust produced at mine sites, is also frequently pelletized so it can be utilized, as opposed to disposed of. The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of ...

The size, high iron content and well balanced additives in the pellets provide steelworks with several production engineering and financial benefits. Due to the fact that the magnetite is converted into haematite during the heating process, heat is generated which is used to heat up the furnace in which the pellets are heated.
It is an agglomerating process of converting iron ore fines into 'uniformed sized iron ore pellets' which can be charged directly into a blast furnace (BF) or into a vertical furnace or rotary kiln normally used for the production of direct reduced iron (DRI). The iron ore pellets are shown in Fig 1.

DRI production. Direct reduction of iron is the removal of oxygen from iron ore or other iron bearing materials in the solid state, i.e. without melting, as in the blast furnace. The reducing agents are carbon monoxide and hydrogen, coming from reformed natural gas, syngas or coal. Iron ore is used mostly in pellet and/or lumpy form.
Pellet Plant Process. Raw material iron ore fines are fed to Iron ore grinding system (IOGS – 160 t/h) for grinding the ore to 85% -200 mesh. We use the wet grinding process for this. The slurry produced is then fed to filter press.
