Iron ore pellets are spheres of typically to be used as raw material for blast furnaces. The process of pelletizing combines mixing of the raw material, forming the pellet and a thermal treatment baking the soft raw pellet to hard spheres.
Several attempts have been made to use iron ore fines in DRI furnaces, such as the Iron Carbide Process, in which the particle size of the iron ore used must fall within a range suitable for bed fluidization, mm to mm, with a tolerance of about 5%; and processes using coalbearing pellets such as the FASTMET process, in which the ...
Pellet Plant Process Raw material iron ore fines are fed to Iron ore grinding system (IOGS – 160 t/h) for grinding the ore to 85% 200 mesh. We use the wet grinding process for this.
Pellets are primarily used in blast furnaces and are also used in DRplants. Occasionally pellets are used in the steel process. Pellets are stored in bunkers before charging to the blast furnace. The mixture of iron bearing materials (iron ore rubble, sinter and/or pellets) and additives (flux material) are known collectively as the "burden".

Jan 01, 2012· The pelletization process is the primary consumer of binders in the iron ore industry. The selection of an appropriate binder type and dosage is of critical importance in producing good quality pellets at a reasonable price. Binders accomplish two very important functions in iron ore pelletization:
Introduction. Iron ore lump, sinter, and pellets comprise the main burden of modern blast furnaces. However, sinter and pellets are now the dominant blast furnace burden, because the natural lump supply has declined dramatically due to depletion of the world''s highgrade competent iron ore resources.

processed ore include sinter and briquettes. The average iron content of pellets is 63 percent. Process Description25,41 Processing of taconite consists of crushing and grinding the ore to liberate ironbearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore ...
A full survey of the laboratory and blastfurnace tests on 2 types of acid pellets is given. From the laboratory tests out in an atmosphere containing hydrogen, it appears that type B, produced out of 100% magnetitic ores, has a far better low temperature disintegration index and a lower reductibility index than type A, produced from a hematite/magnetite mixture.
Electric arc furnaces produce steel from scrap metal. The dust produced in these furnaces is a considerable byproduct and is often pelletized for reintegration into the process. Benefits of Pelletized Iron Ore. In addition to the factors listed above, iron ore pellets also offer a number of benefits to steel producers, some of which include:
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 lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...
Iron ore pellets and Pelletizing processes Pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into oval/spherical lumps of 816 mm in diameter .

Process. Direct reduction processes can be divided roughly into two categories: gasbased, and coalbased. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
