Factors influencing Sinter and Sintering Process
Fig 1 Flowsheet of sintering process. The iron ore fines are natural ore of size 0 mm to 10 mm. The raw mix (also called sinter mix) is made with the weighed amount of iron ore fines, limestone, dolomite, sand or quartzite fines (flux), solid fuel (coke breeze or anthracite) and metallurgical wastes (collected dusts, sludge and mill scale etc).

Characterization of sinter return fines | Semantic Scholar
Sintering is agglomeration of fine grained iron ore for blast furnace burden preparation. During the sinter transportation process fine sinter (–5 mm) is produced which cannot be charged in the blast furnace as high percentage of fines creates gas flow problem in blast furnace. The screened sinter is recycled to the raw material bedding and blending plant. …

Direct Reduced Iron By-Product Fines (DRI D): A Guide …
iron ore burden is such that the ascending column of g ases interfaces with the maximum surface area of the iron ore - the higher the content of iron ore fines in the feedstock, the lower the permeability of the burden. The iron ore feedstock (pellets and lump ore) is therefore screened to remove fines before being charged to the furnace.

Prediction and Optimization of Internal Return Fines Generation in Iron
Prior to dispatch of sinter to the blast furnace for hot metal production, the sinter product from the sinter cooler is screened to remove smaller/finer particles. The undersize so generated is called internal return fines, which are generally recirculated into the sintering machine. A very high level of internal return fines generation limits the use of ore for …
