Pelletization is the process of making spheres of uniform quality iron ore with high carbon content. Iron ore is pelletized so that it can efficiently flow through a blast furnace for smelting. The process involves mixing iron ore fines with additives like limestone, dolomite, and bentonite. This mixture is then formed into balls on a balling disc and fired in a kiln to produce the iron ore pellets. The spherical shape of the pellets allows for better air flow through blast furnaces compared to finer iron ore particles. The pelletization process ultimately produces a product with higher efficiency as a raw material in blast furnaces.

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.

10. Conclusion-
The Product of pellet plant is used as the raw
material for blast furnance. It increase the fuel
efficiency and decrease the fuel consumption rate
of blast furnance.
