Finite element analysis of briquetting of iron ore fines

2019-7-15  Iron ore fines (size less than 6 mm) are created as a result of mining, crushing and processing large ore particles and they may stand for up to 50% of the total ore mined . Iron ore fines need to be enlarged for better handling and transportation but also for increased permeability in the blast furnace. Briquetting is a continuous compaction process to consolidate powders into a block or briquette . In briquetting, ore fines

High-pressure briquetting of iron ore fines

Iron ore fines of 0-2 mm size can be briquetted, without the need forany further grinding. The strength of briquettes depends on the pressure at which the briquettes are formed, particle size of the raw materials and the binders used. Binders contribute maximum to the hardness of the briquettes.
