Benefits for sinter plant operators • 120 years experience of the original inventors of the sinter process
After completion of sintering, the sinter cake experiences hot crushing and enters the blasting circular cooler. Hot crushing is done by single-roll crusher. …
Unlike ISO 3271, the shatter test only simulates the degradation of sinter due to drops during transportation from the sinter plant to the BF. Cold crushing strength. Unlike sinter, pellets are close to spherical in shape. Therefore, the mechanical property of pellets can readily be measured by a compression test.
In steel plants, equipment that processes sinter at very high temperature is exposed to severe wear conditions. In particular, sinter crusher that has to ensure large throughput …
The Flow of Raw Materials. The production of steel requires various raw materials such as coal, coke, iron ore, flux, mill scale, sinter etc. and they undergo processes like unloading, stacking, reclaiming, …
The charge department of the sinter plant (2) provides for the preparation of the charge components, namely solid fuel and flux (limestone, lime). To obtain the required fineness of fuel and limestone, these materials are subjected to crushing followed by sieving (screening).
Sinter machines are of two types namely (i) circular machines, and ii) straight line machines. Straight line machines are also being known as Dwight Lloyd machines. Dwight and Lloyd constructed …
To further improve sinter plant energy efficiency, a number of different types of heat recovery systems are installed at the sinter cooler, where the sensible heat of the off-air is used to generate electric energy or process steam. ... In such a case there is a necessity to control the sinter crushing downstream in the sinter process. Sinter ...
The sintered material is discharged through a finger crusher onto a cooling strand, where ambient air is blown through the crushed material from below. After cooling, the sinter is …
In addition, emissions also arise from material-handling operations, such as sinter discharge, crushing and screening, which result in airborne dust. Read more. View chapter Explore book. ... [24] by various units of the steel plant (coke ovens, sinter plant, blast furnaces, steel shop, rolling mills, and power plant) is shown in Figure 4.2.8.
