Mar 09, 2013 · Sintering process helps utilization of iron ore fines (0-10 mm) generated during iron ore mining operations; Sintering process helps in recycling all the iron, fuel and flux bearing waste materials in the steel plant. Sintering process utilizes by product gases of the steel plant. Sinter can not be stored for a long time as it generate excessive fines during long storages; Sinter generates excessive fines …

Theory and Practice of Sintering of Iron ore – IspatGuru

Nov 25, 2018 · Coke is the best fuel for iron ore sintering. Size classification is a crucial factor. The best economy and efficiency is achieved with a coke particle size of less than 3 mm. Some studies have shown that the best coke size for sinter productivity and reducibility is between 0.25 mm and 3 mm.

Iron ore sintering - ScienceDirect

Like other sintering processes, iron ore sintering converts iron ore fines of often − 8 mm sizing into larger agglomerates, namely, sinter, between 5 and 50 mm particle size, which possess the physical and metallurgical characteristics and gas permeability required for efficient blast furnace operation.

Influence of Iron Ore Fines Feed Size on Microstructure ...

the iron ore feed size in sintering process. In present inves-tigation pot grate sintering experiments were carried out with various size iron ore fines (1.22 to 3.95 mm mean size) to study the influence of iron ore feed size on properties and productivity of the sinter. Various researchers define the sizes of …

Sinter plant - Wikipedia

Sinter plants agglomerate iron ore fines (dust) with other fine materials at high temperature, to create a product that can be used in a blast furnace. The final product, a sinter , is a small, irregular nodule of iron mixed with small amounts of other minerals.

What is the size of iron ore which feeded in a blast ...

Ideally it should be around 15 mm to 16 mm. However if the iron ore is crushed to a maximum size of 16 mm, at least 75% will be less than 9 mm and cannot be directly used. The agglomeration processes (sintering or pelletisation) to make them usable are costly.

What is the difference between pellets and sinter? - Quora

Sep 12, 2016 · DISADVANTAGE OF SINTER. 100% sintered (iron ore) can not be charged in the blast furnace. By sintering one can not create uniform sizes.

Influence of Iron Ore Fines Feed Size on Microstructure ...

Sinter with iron ore mean particle size of 2.59 mm (Classifier fines) yielded better sinter strength with lower fines (–5 mm) and lower RDI. Higher sinter strength is due to effective distribution of acicular silico ferrites of calcium and alumina (SFCA) phases.

Why the quality spread on iron ore products is widening ...

Jul 16, 2014 · The mined iron ore is usually sold to steel makers as concentrate, fines, pellets, and lump. Concentrate ore is processed into separate deleterious …

Control of the stone size distribution of T the raw ...

The raw sinter mixtures contained combinations of Thabazimbi iron ore, Sishen iron ore, coke, lime and return fines. The stone size distributions were controlled by removing the –0.5 mm size fractions of the return fines and coke, and the –1 mm size fraction of lime.

Iron-process sintering of iron ores - YouTube

Sep 30, 2012 · In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres).

Sinter Mix - an overview | ScienceDirect Topics

Ore fines and iron concentrates make the main part of the sinter mix. The stone size of ore fines and concentrates is typically 0–8 and 0–3 mm, respectively. Grains smaller than 0.1 mm are not desired because they reduce the gas permeability of the bed and thus decrease the sintering efficiency.
