· 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.[1][2] Iron ore pellets are manufactured by mixing beneficiated iron ore fines or natural iron ore fines with

· Currently, some plants employ roller screens post-disk/drum systems or just before the induration furnace entrance, underscoring the significance of correct green pellet classification. Proper screening enhances gas flow during the firing process, reducing energy consumption, dust generation, and enhancing pellet quality [ 8 ].

· Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process. In the STG process, a stationary bed of pellets is
