The requirements to the pre-processing techniques are given by the sintering process. Generally coke is blended with the other sinter mix components before granulation. Several studies have shown that the size distribution of the coke in the sinter mix has to be in a range of 1 – 3 mm to obtain high per-formance and good sinter quality ...
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.
Learn about the technology used in sintering, the process that converts fine-sized raw materials, including iron ore, limestone, etc. into product for blast furnace.

5.1 Sintering. Iron ore sintering plants are associated with the manufacture of iron and steel, often in integrated steel mills. The sintering process is a pretreatment step in the production of iron, where fine particles of iron ores and in some plants, also secondary iron oxide wastes (collected dusts, mill scale), are agglomerated by combustion.
Iron ore is used directly in the steelmaking process in the blast furnace in the form of lump ... the pallet has reached the end of the strand where it turns over to the return rails and the sinter cake drops in a crusher for further processing. Figure 1.1.9a illustrates a typical sintering machine [22]. Figure 1.1.9b shows the emission ...

Crushing and screening are integral processes in iron ore processing that help prepare the mined ore for further beneficiation and downstream use. These processes involve breaking down the mined ore into …
For carbon neutrality, the use of sinter should be decreased owing to higher CO2 emission in the sintering process of the blast furnace operations. This trend might contribute to the increased use of iron ore pellets with lower CO2 emission in the fabrication process, high reducibility and gas permeability due to higher mechanical strength. The pelletizing process …
The main mechanism governing the iron ore granulation is "auto-layering", during which the fine-size (−0.25 mm) and intermediate-size (0.25–1 mm) particles adhere to the surface of the coarser (+1 mm) particles of the mixture via water bridges.As a result, iron ore granules have a typical structure of an inner nuclei surrounded by an outer adhering layer (Nyembwe et …
