· Increasing the percentage of metallic feed increases productivity in both vacuum levels; however, the productivity increase was more significant at high vacuum level. This is because high vacuum can bring more air flow per unit sinter raw mix; as a result, sintering speed is higher at higher vacuum conditions [ 4 ].

· The present study evaluated the influence of these pellet fines on the sintering process. 5 experiments were conducted, by varying the pellet fines from 0 to 50% in the iron ore blend. It was found that the productivity decreased from 1.65 to 1.17 t/hr/m2 and sintering time increased from 27.5 to 34.5 min with increas-ing pellet fines.
