The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and low-grade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. …

Sintering emissions and their mitigation technologies. L. Lu, ... X. Li, in Iron Ore, 2015. 18.2.2.5.1 Sinter plant heat recovery. Heat recovered from the waste gas of a sinter plant can be used to preheat the combustion air for the burners and to produce high-pressure steam, which can then be used in steam turbines to generate power. Various systems …
63 Technology for high demanding steel sinter crushers Steel crusher wear issue 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 must be wear-protected in order to avoid expensive maintenance and frequent plant shutdowns.
The sinter grate encounters various types of wear loading, especially abrasion, impact and high-temperature erosion. An optical image of a sinter grate and the temperatures attained in service are shown in Fig. 1. The sinter cake falls 4 m deep onto the sinter grate and the rotating sinter crusher pushes the sinter through the sinter grate.

The search for a high-temperature die-attach materials is driven by the need to replace leaded solder with environment-friendly alternatives [] and to cater the advent of wide bandgap (WBG) semiconductor devices (i.e., silicon carbide (SiC) or gallium nitride (GaN)) which operates at the higher temperature of 300 °C or even 400 °C [].WBG …
The underlying mechanisms were explored through the ... 2014). The quality of iron ore crushing directly affects the performance of pellets and sinter, so as to influence the quality and performance of final steel products (Van Der Meer, 2015). The cone crusher, as a commonly used crushing equipment in the mineral processing and …
The crushing noise peaks from the sinter in the hot crusher can be observed after 0.5, 1.8, 3 and 4.2 min in the image but also smaller following peaks after the main peak at 3–3.5 and 4.2–4.5 min. These vertical peaks reach mainly from 0.10–25 kHz but are also detectable in higher frequencies over the hole frequency bandwidth up to 50 …
A special self-lubricating mechanism of a novel kind of cermet sinter consisting of orderly micro-pores has been investigated at elevated-temperature. Solid lubricant can be stored in these orderly micro-pores and can diffuse to frictional surfaces to provide lubrication. Experiments show that when soft metal, such as Pb or Ag, is used …
At the end of the strand, the sintered product in the form of cake falls off the grate into a hot sinter breaker (primary crusher) where the hot sinter cake is crushed …
The bigger machines have less heat losses and prove energy efficient. The world's largest sinter machine provides 600 m 2 bed area while the largest machine in India at JSW has 496 m 2 bed area. The average bed area of the sinter machine in India is 153 m 2.The sinter cooler technology is available with 11 units in India out of a total 34 machines as …
sinter was poured from the pot into a single-toothed roller crusher for crushing and then dropped con-tinuously 4 times at a height of 2000 mm. After screening and classification, the part with a particle size greater than 5 mm was the finished sinter, and the part with a particle size less than 5 mm was the return fines.

Obtaining an understanding of the sintering mechanisms of Armstrong Ti–6Al–4V powder will help to determine the reason that this powder starts to sinter at lower temperature and densifies faster than HDH Ti–6Al–4V powder [2]. This will help in the selection of appropriate sintering parameters for the Armstrong powder.
Understanding the fragmentation mechanism of agglomerates, which are brittle anisotropic materials with relatively low compressive strength (ranging from 0.5 to …
The sintered material is partly still burning with an average temperature of 800 °C. The function of the sinter breaker is to crush the hot sinter cake into smaller chunks. High temperature abrasion takes place and leads to intensive wear on the rotating crusher stars and the grizzly bars.
sintering process, sinter cake will be crushed and screened after discharge from the machine. Sinter having size > 5 mm will go to the cooler and then it will go to BF. Sinter with size < 5 mm size fines will be re-cycled in the process. 4. Some of critical Equipments/ facilities in Sinter Plant are asunder: Sl. No. Major equipments 1.
the crusher, the size of the crushed product directly affects the economic interests of users, so it is necessary to study the crushing mechanism of sinter ore. In the field of …
In this paper, five particulate emission points from a sinter plant in China, including anthracite crusher, raw material blender, sinter strand, screener, and circular cooler, were selected for particle sampling. The particle size distribution, the toxic element content (As, Cd, Co, Cr, Cu, Ni, Pb, Ti, and Zn), and the morphology of the samples …

V–Ti–Cr sinter is an important product in achieving the utilization of V–Ti–Cr fines. To date, the sintering behaviors and consolidation mechanisms of V–Ti–Cr fines have not yet been made clear, significantly influencing the productivity, sinter quality, coke content, sinter cost, BF performance, and furnace life of these materials.

Hot sinter crusher. At the end of the sintering machine's pallet car line is a hot sinter crusher, which reduces the sintered ore into pieces of less than 150 mm. Since the crusher processes material at a temperature of over 800°C, its design must be adapted to this harsh environment. ... This mechanism ensures that all the material falls into ...

A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...
