Iron Ore Pelletizing Process: An Overview IntechOpen

Pellets are obtained byadding an appropriate amount of water to the iron ore concentrate; this is a fundamental factor in the formation and growth of pellets, which creates a surface tension that holds the mineral grains cohesive, thus allowing their handling [6, 8]. This cohesive tension of fine particles due to water is called neutral tension.

Both straight grates and grate kilns dry the pellets out in a drying section, then bring the pellets up to a temperature of about 800-900 °C in a preheat zone, then finish the induration process at roughly 1200-1350 °C. The pellets are then cooled to a suitable temperature for transporting to a load out facility.

Iron Ore Pellets and Pelletization Process IspatGuru

Nov 26, 2014For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is transported on an endless travelling grate through the drying, oxidation, sintering and cooling zones.

Iron ore pelletization ScienceDirect

Jan 01, 2022Although iron ore concentrates are generally higher in iron grade and contain lower impurities, the finer size distribution of concentrates limits their usage in iron ore sintering. Therefore, pelletizing is needed to produce fired pellets from concentrates as burden materials for blast furnaces and direct reduction (DR) processes.
