Cold briquetting of sponge iron (CBSI . - Taylor & Francis Onlinereduced iron is introduced. Experimental results from laboratory and pilot plant tests show the success of the method which has been named cold briquetting of sponge iron. The optimum condition for briquetting is achieved at 80 kN (Lcm)21, 6% binder, 10% sponge iron fines and 4% anthracite. While hot briquetted iron.iron ore fines cold briquetting process,Direct Reduced Iron (DRI) - GARDpossibly in an attempt to achieve a reduction in the carriage requirements as afforded to real HBI. The fines can be either simple DRI fines which have been completely misdescribed by the shipper, or fines produced during production of HBI. If the fines have been produced after the HBI briquetting process then it is possible.

Part-1 - Indian Bureau of Mines

I Briquetting t. Briquetting is the earliest process for agglomerating iron ore fines. It is defined as the compaction of fine particles by application of high pressure in a more or less close mould to produce agglomerates of suitable size. It can be done hot or cold and with/without binder depending upon the nature of materia.

Carriage of DRI - North of England P&I Club

or lumps. Although the process is conducted at high temperature, this is still substantially below the melting point of iron. This means that the lumps and pellets retain . DRI fines. The DRI production process (and the hot-briquetting process if HBI is being produced) generates copious quantities of dust or 'fines'. These fines.
