Detailed introduction

agglomeration of iron ore by pelletisationAgglomeration processes combine small, discrete particles into larger aggregates, where the individual particles are still discernible (Ennis and Litster 1997). During iron ore agglomeration or pelletization, moist iron concentrate particles and flux materials are rolled into balls with the aid of a binder (Figure 1).Iron Ore Agglomeration TechnologiesPelletization is an agglomeration process of iron ore concentrates with a granulometry lower than 150 m and low concentration of impurities [10, 11]. This iron ore is mixed with water, bentonite (or other organic binders less expensive and contaminant [12]), and lime and treatedagglomeration pelletizing - thebushlodgePelletizing discs. Pelletizing discs are used in the agglomeration process to form fine iron ore into uniform green iron ore pellets. State-of-the-art operators control station allowing operator to locally start and stop the disc, adjust the speed of the .
