Sintering of iron ore is a process [5,6,8] in which air is drawn down through a bed of raw mixture of iron ore, limestone, coke and other minor additives. The iron ore may be natural ore, which usually has a particle size up to 10mm, or concentrate which is very fine with a particle size usually less than 150^m and over 50%. The raw

these materials can contribute to a finer particle size distribution between one to three millimetres. Addition of pellet screenings on the other hand effect a coarser particle size distribution when added to the reference sinter mix. The respective curves for the four different blends can be seen in Figure 1.

ABSTRACTThe main unit operations of pelletizing process are grinding, filtering, pressing, pelletizing, and firing. Grinding, the first operation in the process, is a crucial step for the subsequent operations. Three iron ore mixtures with different grindability index (low, medium, and high) were used in order to verify the influence in the operational parameters such as production rate ...
