The Pelletizing Process. The production of iron ore pellets from fines to finished product can differ based on a variety of factors. As such, it's important to note that the process described here is a generalized approach subject to many variations. In general, three primary phases occur in iron ore pelletizing: Mixing/Preconditioning

Iron ore pellets are small and hard spherical particles agglomerated from a fine iron ore concentrate. They are used in the blast furnace process to produce hot metal. The diameter of blast furnace pellets is usually between 8 and 16 mm. In this study, a batch of magnesia iron ore pellets was first sieved into particle sizes of 810 mm, mm, mm and 1620 mm, and the four ...

As highgrade iron ore deposits become more limited, it is necessary to upgrade lower quality iron ore resources through concentration. The ground iron ore must be pelletized prior to feeding into a blast furnace or DRI plant. Our pelletizing equipment is designed to produce pellets of highest quality at the lowest cost.

composed of spherical iron ore pellets that descend by gravity. The pellet diameter (dp) is assumed to be unique and unchanging during the reduction reaction, and the initial pellet composition is known. The gas phase is composed of six species: H2, CO, H2O, CO2, N2, and CH4. The reducing gas is injected from the sidewall, at a height of z = H
