The agglomeration process in which lumps are made by compacting the iron bearing fines and dust with addition of binder and also de-airing these mixtures inside the vacuum chamber of the briquetting machine. So, briquetting process is developed to meet these demands. This process aims at recycle and reuse of the low grade iron ore and plant fines.
The schematic represents the HBI briquetting process. Direct Reduced Iron is discharged hot from the reduction furnace and screw-fed into the nip between two counter rotating rollers. Pockets in the synchronously rotating rollers form the briquettes. This process occurs at high temperatures (typically approx. 700 C) and high pressing forces.
During direct reduction, oxygen is removed from iron ore in solid state. This procedure results in a spongy structure of the product, thus Sponge Iron, with a high porosity. De-pending on the raw material and the reduction process applied, apparent product density is approx. 2 g/cm associated with a very high specific surface area. The ...

Fote iron ore fines briquetting machine is the most ideal equipment specially designed for processing these iron ore fines. This iron ore fines briquette machine can be used to compress iron ore fines, iron powder, mill scale, steel powder, ferrosilicon powder, etc. to form differently shaped briquettes that are rigid and unbreakable in the
Fines from Direct Reduced Iron (DRI) Fines ranging from 6 to 40% arise when iron ore is directly reduced. These fines are difficult to handle and to process in a melting vessel. Thus size enlargement is required. In the briquetting process, fines are usually bound using water glass with hydrated lime.
Generally, variation in the concepts of the origin of ferrous iron can be listed in four branches. Firstly, that iron was drifted towards the water of the adjoining land. Secondly, that iron was gathered through in deep stationary oceans through upwelling. The third concept is related to

GoodRich offers high-pressure briquetting plant from a specialized manufacturer in China, to briquette iron ore fines. These briquettes can be used in the rotary kilns for making sponge iron. Briquetting is an agglomeration process, similar to pelletizing or sintering, but without the need for thermal processing.
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 ...
Five iron ore agglomeration technologies can be defined briquetting, nodulization, extrusion, pelletization and sintering.
