Iron Ore Agglomeration Processes and their Historical

28/12/2015· Iron Ore Agglomeration Processes and their Historical Development. There are four types of agglomerating processes which have been developed (Fig 1). They are (i) briquetting, (ii) nodulizing, (iii) sintering, and (iv) pelletizing. Fig 1 Agglomeration processes. Briquetting is the simplest and earliest applied process. Fine grained iron ores are pressed in to pillow shaped briquettes with the

Applications koeppern-international

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. There are alternatives of equivalent quality, such as sulfite lye or molasses. For the cold briquetting of sponge iron, specific

Cold Briquetting Maschinenfabrik Köppern

Cold briquetting is a widely-accepted process for the compaction of granular material. Using roller presses for the briquetting process, material can be compacted to a defined form and size, enabling its inherent resources to be utilized in subsequent production cycles. Common applications for cold briquetting are: The processing of steel mill residues; The processing of fines from direct

Briquetting an overview ScienceDirect Topics

Ore fines are first preheated in R3 to approximately 300 °C, prereduced in R2 to about 20–30% reduction, and finally reduced in R1 to a maximum reduction of about 80%. The temperature of fine particles in R3 is likely to be about 300 °C, R2 to be about 500 °C, and R3 to be about 700 °C. The DRI fines from R1 are compacted into HCI (hot compacted iron) and then charged into the melter

Cold Briquetting of DRI Fines for Use in Steel Making

For agglomeration of these fines, a suitable binder is required. Iron ore-coal composite pellets were prepared by cold bonding. Various binders such as lime, Ca(OH)2, slaked lime, dextrose

Cold Briquetting of DRI Fines for Use in Steel Making

It is difficult to directly use such iron-rich material in the primary steel making process, without agglomeration. At JSW Steel Vijayanagar, around 50 to 70 tons per day of DRI fines with < 2 mm size fraction get generated. The fines are used in base sinter mix or it may be agglomerated suitably to use it as a coolant in the primary steel making process. Since the fines are extremely reactive

HBI production International Iron Metallics Association

HBI Briquetting Process. 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. The continuous string of

FINES RECYCLING PLANT- COLD BRIQUETTING OF FERROUS

The by-product fines, with an average iron content defined by the process are collected directly in and at the HBI plant complex and utilized in the cold briquetting plant located centrally within the plant complex. The pellet fines generated at the screens are collected in an intermediate storage silo and transported to the briquetting plant, without any additional handling. The dewatered

SPONGE IRON WELCOME TO IGR INDIA

The methodology envisages cold briquetting of iron ore fines and reductant coal along with limestone/dolomite flux as compared to traditional high temperature agglomeration method. This amounts to lesser investment, easy operation and low input material handling cost and more environmental friendly.
