  • Introduction to Iron ore Pellets and Pelletizing processes

    Induration During the induration, heat hardening of green pellets is carried out. Induration of green pellets consists of three main steps namely (i) drying of green pellets, (ii) firing of pellets at around 1300 deg C to sinter the iron oxide particles, and (iii) cooling of hot pellets before discharging.

    The green pellets are then fed to the induration machine. 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. Both processes recycle the heat from the pellet back through the process

    Abstract: We present a mathematical model of iron ore pellet drying and induration in an industrial scale application, and validate it against measured data. The model is based on the laws of mass and heat transfer, and incorporates both physical and chemical processes. The partial differential equations of the process kinetic model involve derivatives in time and bed depth.
