• There are several iron ore pelletizing processes/technologies available in the world. However, currently, Straight Travelling Grate Process and Grate Kiln Process are more popular processes. • The pellet plant in eastern region use either travelling grate technology with dry grinding or Grate Kiln technology with wet grinding technology.
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. There are several iron ore pelletizing processes/technologies available in the world.
For carbon neutrality, the use of sinter should be decreased owing to higher CO 2 emission in the sintering process of the blast furnace operations. This trend might contribute to the increased use of iron ore pellets with lower CO 2 emission in the fabrication process, high reducibility and gas permeability due to higher mechanical …
