pelletizing of sishen concentrate scielo. briquetting is one of the oldest iron ore agglomeration methods but it has since been replaced by sintering and pelletizing briquetting is the process where a mixture of fine ore concentrate and binder is compressed in a briquetting die to form a product with uniform size and shape developments of briquetting techniques such as hot
mar 09, 2013 the process of sintering begins with the preparation of the raw materials consisting of iron ore fines, fluxes, in-plant metallurgical waste materials, fuel and return fines of the sinter plant. these materials are mixed in a rotating pelletizing drum and water is added in order to reach proper agglomeration of the raw materials mix.
pelletizing discs are used in the agglomeration process to form fine iron ore into uniform green iron ore pellets. green pellets are feed to a travelling grate or grate kiln. applications. pelletizing discs are used in iron and steel plants. can also be used in.
include iron scrap, reduced iron pellets and reduced iron briquettes. sintered ore is made by partially melting and sintering coarse iron ore 1 to 3mm in size into products having a size of 15 to 30mm. the sintering process uses the combustion heat of coke breeze (fuel). pellets are
