Jul 13, 2021 Pelletizing is the process of converting very fine iron ores into spheres (normally 8mm-20mm in diameter), known as pellets. These pellets are suitable for both blast furnaces and direct iron reduction processes. Pelletizing normally has four processes: (i) receipt of raw materials, (ii) pretreatment, (iii) balling and (iv) induration and cooling
