Prediction of the granule size distribution of iron ore sinter

1 Introduction Granulation is the first stage in the agglomeration of iron ore for sinter production Fine iron ores, fluxes, coke breeze and other fine materials (collected dusts, mill scale) are mixed together to form large and bigger agglomerates , , , The primary objective of the granulation process is to produce granules with large mean size and narrow size distribution,A coarse size distribution of feed material in the lower bed region is therefore desirable Iron ore sinter typically constitutes more than 60% of the blast furnace ferrous burden in modern blast furnaces in East Asia Indication of the measurement of surface area on iron ore granulation ISIJ Int, 51 (2011), pp 14321438Iron ore sintering ScienceDirect
