iron ore fines cold briquetting process Chauffage Nanni. iron ore fines and coke fines with the addition of Portland cement as a binder and clay as a,, had its 1st industrial application in the year 1993 1 In this cold briquetting technology various steel plant by products can be easily agglomerated using very few amount of binder,The industrial stiff extrusion process lines shown in .
The cold briquetting is a way in which all the materials required in the production of the metallurgical industry are uniformly mixed, then subjected to a roller briquetting press for the cold briquetting work, and dried at a low temperature to get the finished briquette.
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 reduced iron
The removal and recycling of the fines generated during briquetting back to the press by means of a screen and elevator is a possibility. The hot briquetting process is a reliable and recognized sponge iron passivation technique that enables to obtain a secure product, allowing easy handling, storage and transport.
3.2 Briquetting Studies: Metallic fines show a different binding behavior comparedto conventional ore particles. Figure 6 shows surface of manganese ore and ferromanganese metal particles. The ore particles usually contain small cracks andcleavages which play important role in binder absorption and binding of theparticles.
The briquetting press can be used for iron ore, bauxite, dolomite, limestone, manganese, chromium, sponge iron etc. The roller skin of the briquetting press is made up of special bearing steel with 6,000 hours of ultra wear resistant material. Completely sealed gearbox is used for the reducer, for low noise and for prevention of oil leakage.
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.
Usually, briquetting is done with iron ore, fluxes, coal and process wastes. In the present study, DRI fines are the major component. Hence, the briquetting is done uniquely with a significant metallized input raw material product.
The present work describes the possibility of cold briquetting of fine iron ore to produce DRI in several cost effective ways using certain novel technologies developed during...
