The process of pelletization enables converting Iron Ore Fines into “Uniformed Sized Iron Ore Pellets” that can be charged into the blast furnaces or for Production of Direct Reduced Iron (DRI).
Pellets are uniform size, with purity of 63%- 65% contributing to faster reduction and high metallization rates. Pellets with their high, uniform mechanical strength and high abrasive strength increase production of sponge iron by 25% to 30% with same amount of fuel.
Benefit of Iron Ore Pellets:-
- Iron ore pellets are superior to iron ore lumps in the subsequent iron making processes such as Blast furnace, DR furnace etc.
- Iron ore pellets with a nominal 64- 67% Fe, uniform porosity and better size help in faster reduction and higher metallization rates than the conventional iron ore lumps.
- The inherent higher mechanical strength and abrasion resistance of pellets enhance the production rate of sponge iron by approx. 20% under identical operating conditions.
- Iron ore pellets are of spherical shape with a size range of 9-16 mm.
- Iron ore pellets are not vulnerable to degradation during transportation due to their high abrasion resistance.
