Mechanisms in oxidation and sintering of magnetite iron ore green pellets

After drying, the bed of green pellets is transported through the temperate preheat zone (TPH) and the preheat zone (PH), where the main part of magnetite oxidation takes place. The temperature of the incoming gas at the PH zone is around 1150–1250 °C. The gas flow rate is in the order of 6 m/s and the oxygen content of the gas is 16 to 18%.
