Sintering Technology for Iron ores and Optimization of ...

19/10/2016  The hot sinter crusher reduces the lumps of sinter cake to a size smaller than 150 mm, in preparation for cooling and secondary crushing. Since the sinter cake retains a temperature of around 850 deg C at the time of leaving the strand, the hot sinter crusher operates in a very hostile environment. Hence the design of the hot sinter crusher is to take care of this hostile environment.

What Is Iron Ore Sintering? (with pictures)

14/01/2021  Specifically, iron ore sintering requires the use of fine ore, produced by crushing high-grade iron ore into particles only a few millimeters in diameter. Depending on the specific machine and iron ore sintering process used, substances such as coke breeze and burnt limestone are used to ignite and heat the iron ore particles until the particles congeal. Once congealed into an agglomerate, the ...

Effect of Iron Ore Particle Assimilation on Sinter Structure

During iron ore sintering, a packed bed of uniformly dis-tributed granules—composed of a range of iron ore types, fluxes, fuel, return sinter fines and plant dusts—is trans- formed into porous sintered particles of irregular shape. The yield of the sinter machine (i.e. the percentage sinter acceptable for use in the blast furnace) governs its produc-tivity and is closely dependent on
