Magnetite iron ore pellets are produced by agglomerating moist, finely ground magnetite concentrate together with a binder in balling drums or balling discs to pellets, typically between 9 and 15 mm in diameter. In the Grate Kiln pelletizing process, the wet green pellets are loaded on a travelling grate with a bed height of 23 cm.
May Concentrate Iron ore, as a refractory iron concentrate, deteriorates the permeability of the sintered layer during the sintering process due to its fine particle size and poor granulating performance. Therefore, it cannot be widely used in iron ore sintering. In this study, the strengthening granulation of May Concentrate Iron ore …
