Dri hot briquetting machines

Aug 03, 2021

Hot DRI in the form of pellets, lumps, fines at a temperature of 650-850 deg C is passed through hot briquetting machine where the product is pressed between the rolls at extremely high pressure to produce highly compacted pillow shaped material called hot briquetted iron (HBI)

    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
