iron ore briquetting process

A method of producing an iron one briquette that is suitable for use as a blast furnace or other direct reduction furnace feedstock which includes the steps of: (1) mixing: (i) ore having a predetermined particle size distribution with a top size of 4.0 mm or less; and (ii) a flux; to form an ore/flux; (2) adjusting the water content of the ore prior to or during mixing step (1) to optimise

    Study on Direct Reduction Process of Cylindrical

    There are two types of iron resources such as primary iron ore and iron sand. In general, primary iron ores use as raw materials in iron and steel making and can reduce directly. In Direct reduction process, Fe2O3 (hematite) is converted to metallic iron by the removal of oxygen.

    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
