A combined model for granule size distribution and cold bed

Iron ore sintering is an important step in ironmaking by the blast furnace route. Sinter now accounts for more than 70% of the blast furnace burden. Raw sinter feed consisting of iron ore fines, coke breeze, limestone, lime, dunite or dolomite and the return sinter fines is initially agglomerated in a rotary drum.
