Introduction to Iron ore Pellets and Pelletizing processes

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.

ABSTRACT The behavior of iron ore pellet binders is complex. Any pellet binder is subject to a handful of practical requirements: that it be readily dispersed through a pellet, that it effectively controls the movement of water within the pellet, and that it contributes to the interparticle bonding within the pellet. Meeting these requirements leads to the formation of strong pellets by ...
