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 feed is placed on a sintering bed, where thermal agglomeration (1300-1480 °C) takes place to produce clustered lumps, aka iron sinter (5-20 mm in size). At a common sinter plant, the following sinter quality parameters need to be controlled: Basicity, CaO/SiO2 – FeO (Fe2+) Sinter strength index, SSI. Tumbler index, TI.
SINTER COOLING1) The process involves Cooling of sinter inside circle cooler. 2) The sinter cake discharged from the hot sinter breaker, 120 ~ 0 mm, at temperature of 750 ~ 850 deg. C in average is charged into circular sinter cooler. 3) Product Sinter temperature should be reduced down to < 100deg.
Sinter is the primary feed material for making iron in a blast furnace. According to the U.S. Environmental Protection Agency, the sintering process converts fine-sized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of suitable size for charging into the blast furnace.
Process Control of Sintering Plant. Sulfide concentrates, oxide materials and I.S.F. dross are prepared in the proportioning bins (There are ten bins for raw materials.). The raw materials and flux are fed by separate variable speed belt conveyers consisting of computer controlled belt weighers. Raw materials and crushed return sinter …

Sintering is a process where a mixture of ore, flux and coke is agglomerated (agglomerated) in the sinter plant to produce suitable sintered products in terms of composition, quality and...
Sinter plants are the major contributor to dust emissions from integrated ironworks and steelworks. The dust emissions from sinter plants are generated from raw material handling, wind box exhausts, the discharge end of the sinter strand associated with sinter crushers and hot screens, the cooler, and cold screens.

Our iron ore pelletizing systems combine the best features of both technologies to provide the most modern plant and to produce pellets at the lowest cost and highest quality. Pellet plants sized from 1.2MTPA to …
Mixing and nodulizing drum is a large equipment in sinter plant used for granulation of sinter mix. In sinter plant 3 at Tata Steel Jamshedpur, its main dimensions are 4000 mm diameter and 5000 mm length. It is designed for interior to act as mixing drum 33% of total length and nodulizing of sinter mix remaining 67% of total length.

The third difference in the chemistries of BF pellets and sinter is shown by the binary basicity (B2) defined as the ratio of CaO/SiO2. While for BF pellets the B2 ratio is typically around 0.8-1.1, for sinter this ratio is commonly greater than 1.7. Such a high basicity is required to improve sinter properties and achieve enough strength to
In our sinter plants (Ghent), we bake a mixture of fine iron ores, ferruferous recuperation materials and fluxes. This is done on a slow moving grid conveyor belt which uses coke breeze as its fuel. The grid conveyor belt …
The function of the Sinter Plant is to supply the blast furnaces with sinter, a combination of blended ores, fluxes and coke which is partially 'cooked' or sintered. In this form, the materials combine efficiently in the blast …
The sinter plant turns iron ore into sinter, which is the optimal product for the blast furnace. Sinter is made by burning a mix of iron ore powder, fluxes and recycled substances from the steel plant to create an open-grained, consistent substance. The sinter is then crushed, cooled and screened for dust. Sometimes, iron ore is supplied in the form of iron ore pellets.
Similar to sintering, pelletizing is another widely used process to agglomerate the iron ore. Sinter plants are usually located near the blast furnace plant, but …
The continuous sintering process was invented more than 60 years ago by two metallurgists, Arthur S. Dwight and Richard L. Lloyd, who saw a need for automation in mineral processing. ... operations of conventional practices are recognized as one of the highest maintenance and lowest attended areas of the sinter plant.
