binder is rolled up in a mechanical disc or drum to produce agglomerates (green or wet pellets) (Sivrikaya and Arol, 2010). A narrow size distribution in green pellets is an important criterion for the pellet quality because high permeability in the pellet bed is beneficial for reduction process in .
Dec 28, 2015· Pelletizing of iron ore is a method of Swedish origin, patented in 1912 by AG Andersson (Yamaguchi et al., 2010). The process was developed in the USA in the 1940s, and the first commercial plant started operation in Babbitt, Minnesota in 1952. The first iron ore pellet plant of the grate-kiln type was established at Humboldt Mine, Michigan in ...
1. Introduction. Green iron ore pellets are nearly spherical agglomerates produced in balling discs or drums from a mixture of fine iron ore concentrate, agglomerating agents and water [].These pellets are then indurated, typically in horizontal travelling grate furnaces, reaching their hardened state which allows handling without significant mechanical degradation from the pelletizing plant ...
Jul 10, 2020· Iron ore pellets are small ball shaped agglomerates that are used in production of steel. Growing demand for steel products in the end-user sectors including construction, automotive, consumer goods are estimated to drive the iron ore pellets market by 2026.
Blast furnace iron ore pellets are sintered, centimetre-sized ore spheres with a high iron content. Together with carbonized coal, iron ore pellets are used in the production of steel.
Nov 13, 2006· From the balling of iron ore concentrates, it is known that as the raw material becomes finer, the moisture content needs to be increased to preserve the ballability of the pellet feed. Therefore, if the moisture content for the finest material was too low, the consolidation rate would have changed due to different plasticity in the agglomerates.
A balling disc machine also known as pelletizing machine is a specialized equipment It is used for pelletizing of powder materials into balls pellets of agglomerates It is original and peculiar with largescale discpellet machine and designed on the basis of the large. View More Details
May 22, 2013· Figure 1 Green-ball growth during iron ore agglomeration. Individual iron ore particles are wetted, and pellet 'seeds' are nucleated. During agitation in the rotating drum or disc, small seeds can grow by consolidation of individual granules and layering of new feed material
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
A process for the reduction of iron oxides to produce molten iron in which olivine is introduced into a blast furnace in addition to iron oxide bearing materials and in which there is a high content of alkali metal oxides in the materials charged into the furnace, resulting in minimizing or preventing "scaffolding" and improving the operation of the furnace.
Mar 20, 2013· Pellet growth is controlled by the small amount ofwater sprayed in the disc and the adjustment in the disc rotational speed.A pellet plant contains a series of balling drums where the iron ore concentrateis formed into soft pellets, in much the same manner that one rolls a snowball,to make a pellet about the size of a marble (between 1/4" and 1 ...
Iron Ore Pellets and Pelletization Process. Pelletizing of iron ore was started in the 1950s to facilitate the utilization of finely ground iron ore concentrates in steel production. For the pelletizing of iron ore there are two main types of processes namely, the straight travelling grate (STG) process and the grate kiln (GK) process.

Iron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces.They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets.
The balling area is where the powdered ore is mixed with water and rolled in rotating drums to create spherical balls. The green balls are spherical agglomerates nominally 12.5 mm in diameter, formed by rolling a moist mixture of finely ground iron ore concentrate, binder and sometimes a flux.
The disc balling machine is used in the balling granular used to make damp granule into antique pellets. [1]–[3]. It is equally used in the palletizing and alkaline leaching of powdery low grade zinc oxide ores [4]. It is also used in the mines. Disc balling granulator is suitable for mixing material pelletizing equipment with nutrient [5].
The production of steel from iron ore has increasingly been employing the pelletizing or balling technique as a result of the many benefits it can offer, combined with changes in the market that have made pellets more favorable. Below is a look at this critical process. Preparing Iron Ore for Pelletizing (Balling)

Iron ore pelletizing systems. Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel.
