Pelletizing
Annual production capacity: 4 Million Tons
The iron ore must be pelletized to 8-18 mm pellets to feed the direct reduction unit. This process is called pelletization.
Pellet manufacturing combines chemical, thermal and mechanical processes to give it the required homogeneous composition. The granulation is done in a humid environment in saucers to ensure the cohesion of the material. The porosity of the pellets promotes chemical reactions in the direct reduction unit. Once the ore is compacted the pellets are cooked through burners to enhance their cohesion and eliminate unwanted elements. The pelletized iron facilitates handling and has a higher iron content than the chipboard. The iron ore is now ready for direct reduction
