Description
Size segregation of the iron ore granules packed on a sinter strand has a significant influence on both airflow rate and temperature distribution through the bed. Therefore, it is a key factor that governs the efficiency of mass and heat transfer down the sinter bed. For a defined sinter feed and granule size distribution, it is possible to increase the size segregation through optimising the operating parameters in a sintering process. In this paper, a numerical study was carried out using a 3-D model developed by Discrete Element Method (DEM) to investigate the influence of feed rate and the inclination of rill plate on the level of granule size segregation down the bed. The optimal combination of these two parameters for obtaining a desirable level of size segregation was also studied. These simulation results were validated using a 1/3 scale laboratory sinter strand utilising iron ore granules.
