2. Pelletization Prosess Pelletization is the process of making spheres of high carbon contains uniform quality iron ore. Necessity of pelletization - The configuration of iron ore powder in the blast furnace is more tightly packed and restricts the air flow .For free air flow the powder of iron ore should be in spheres. The configuration of iron ore pellets as packed spheres in the blast furnace allows air to flow between the pellets, decreasing the resistance to the air that flows up through the layers of material during smelting. This is the reason that iron ore is referred in the form of pellets rather than in the form of finer particles.

3. Needs for pelletization – Some Other particles are needed to Spherise the Iron fines. These materials are as follows:- Lime stone Dolomite Bentonite Coal Fins Proportion :- These materials are mixed with the iron ore powder in certain proportion. Per 1 ton iron ore dolomite and lime stone - 200kg bentonite - 200kg coal - 100kg fins - as per moisture condition .
