dri hot briquetting machines

Mar 16, 2020 Sponge iron (DRI, HBI) briquette making and the briquetting machine. Sponge iron, also name as direct reduced iron (DRI), is the resulting product (with a metallization degree greater than 82 percent) of solid state reduction of iron ores or agglomerates (generally of high grade), the principal constituents of which are Metallic iron, residual iron oxides carbon’ and

    Dec 14, 2013 The hot DRI is sent to briquetting machines to compress it into pillow shape briquettes with typical dimension of 30 mm x 50 mm x 110 mm. HBI is 50 % denser than the CDRI and because of this the tendency of re-oxidation of HBI is reduced greatly. This enables HBI to be stored and handled without any special precautions as recognized by the IMO

    After the iron oxide is reduced, the hot DRI (HDRI) is continuously discharged at 650 C or higher into a product discharge chamber (PDC), which purges any combustible gases from the HDRI bed and smooths out any production surges. The purge gas is externally heated to keep the HDRI at the proper briquetting temperature
