Pelletizing is a process which involves mixing of very finely ground particles of iron ore fines having a size which is less than 200 mesh ( mm) with additives like bentonite and then shaping them into near oval/spherical balls having size in the range of 8 mm to 16 mm in diameter by a pelletizer and hardening the balls by firing with a fuel.

The dominant process adopted to produce iron ore pellets in China is the gratekiln process [1012]. The preheated pellets roll in the rotary kiln and can be sintered uniformly; therefore, it is known that the gratekiln method yields a superior and more consistent pellet quality compared with the straightgrate process [13].
