Iron Ore Pelletization: Part I. Fundamentals | Semantic Scholar

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 ...
