Iron ore pelletization technology is needed due to the increasing amount of iron ore fines produced during mining. Pellets have excellent properties for transportation and are needed to utilize low grade iron ores. The pelletization process involves forming green balls from iron ore fines and water, then drying, preheating, and heating the balls to form hard …
