Project On Iron Ore Sintering

The agglomeration process begins with the preparation of the burden mix for iron ore sintering and includes the following stages: material sizing, burden components dosing, mixing, moistening and pelletizing of the burden. Fine iron ore concentrate (<0.074 mm) and sinter ore fines (<10 mm) do not need crushing.

Sustainability. The global steel industry uses fossil fuels to produce millions of tonnes of iron ore sinter each year. Sintering is an energy-intensive process that fuses iron ore and flux to produce material that balances a high mechanical strength at a sufficient particle size to ensure a macroporous burden in the blast furnace to enable rapid gas flow.

Abstract. Flue gas recirculation has been introduced into iron ore sintering process to reduce pollutant emissions. Compared with the conventional process, the sintering indices reduce gradually with decreasing O 2 content in the recirculating gas. With sufficient O 2, the principle on the use of flue gas recirculation is proposed.The heat loss caused by the decrease in O 2 …

In the iron ore sintering field, the yield, productivity and tumbler index (TI) is commonly used to characterize the sinter quality [19]. The yield (%) is the proportion of the mass of the sinter with a size greater than 5 mm after crushing and screening minus 1 kg ore at the bottom of the hearth layer to the total mass of the sinter.
