    Jan 17, 2013 Hot briquetting of the DRI can eliminate this concern by drastically reducing the surface area, while improving the heat conduction capacity of the material through a compaction process. Process Hot briquetting is carried out by compacting feedstock at temperatures ranging between 250 and 800C through a pair of briquetting rollers.

    DRI does not allow the heat to escape. So, overheating and meltdown of DRI (which is stored in piles) occurs. So due to this Hot Briquetting process has been developed. In this technique, the direct reduced iron is applied with high pressure immediately after it reduction at high temperatures. The high

    Following its industrial development in the 70s and 80s, hot briquetting is now a fully-accepted, reliable technology for the passivation of direct-reduced iron (DRI) to turn it into the more convenient form of hot-briquetted iron (HBI). Materials are briquettable under hot conditions if binding characteristics are activated at high temperatures. The most common application is the production of hot briquetted iron (HBI) from direct reduced …

    Hot DRI briquette machine. Hot DRI is a better material than cold DRI, it is a material with much higher temperature (normally around 650-700 Celsius) and stronger plasticity, the hot DRI briquette is with densified form and lower gas content. Hydraulic briquetting machine is a way to make the hot DRI briquette with a reasonable investment.

    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.
