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 inter-particle bonding within the pellet.

The iron ore pelletization is the process of converting iron fines less than 200 mesh (0.074 mm) into 8-16 mm pellets. Types of iron ore pellets Iron ore pellets are normally produced in two types of quality grades: DRI grade and BF grade. DRI pellets have a higher quality requirement, containing more than 67% iron content.
