1.1.3.2.2.1 Pelletizing Process. 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 pelletizing plants are often located near the mining site. Some works have both pelletizing and sintering plants at the smelter sites. 1.1.3.2.2.2 ...

You talk about the concentrate mass increase when reporting to the pelletizing plant, then about the pelletizing reaction which occurs in the plant. The process generally involves combining the concentrate with a binder which will have a minor increase in mass, followed by a sintering process to harden the pellets, which will drive off moisture ...
as the implementation of pelletizing disc to generate minipellets (4-9 mm) or even normal pellets (9-16 mm). The so-called Hybrid Pelletization Sinter technology (HPS) separates the mixing procedure of the normal sinter feed from the fines. The fines are treated on separate discs and the produced pellets are led together with the sinter mix . 696
Aiming to increase sinter production combined with the use of of its own iron ore, the Hybrid Pelletized Sinter (HPS) process, developed by JFE (former NKK), was chosen among other alternatives. The HPS process started up at Monlevade Works in December 2002 and since January 2003 of Andrade iron ore has been used at the sinterplant.

Sintering behavior of pelletizing feed in CAP has not been studied fully yet. In this study, individual pellet and simulated CAP cells were roasted under the simulated sintering conditions. The compressive strength, FeO content and microstructures of roasted samples were investigated. The results show that pelletizing feed either from magnetite ...
pelletizing process can operate at lower basicity compared to the sintering process, requiring much lower flux additions as a result. Flux additions have a net diluting effect on the Fe content, so it follows that the Fe content of pellets is less diluted than that of sinter.
Pelletizing is the most widely used process for the size reduction of many thermoplastic materials, including raw polymers and mixed compounds. The process involves extrusion through a die.
Hot metal production using sinter and pellets in the blast furnace is compared, considering aspects like; blast furnace productivity, environmental performance, solid waste management, slag-coke...
The energy consumption of pelletizing process is less than 50% of that of sintering process, and the emissions of flue gases, dioxins, nitrogen oxides, and dust are also significantly lower than that of sintering [ 2 ]. The development of pelletizing is an important measure for green ironmaking.
