The Design Of 2 Million Tons Pellet Production Line In Ben Steel

Along with the found of large size blast furnace in Ben Steel,the higher quality of raw materia for blast furnace is required. Pellet is a kind of nice raw materia,and also adapt to Ben Steel. So it is necessary to build a production line.The drying grate-rotary kiln furnace pellet production line include:raw materical preparation,confection,mix,pellet making,Layout material,the raw pellet dry and the preheating,oxidizing roasting,cooling and product transportation.In these, pellet making,the raw pellet dry and the preheating,oxidizing roasting are important tache.They are determinant for the quality,the output,the performance of the pellet.The article investigates every part after of technics parameter about a 2,000,000 mt/y drying grate--rotary kiln furnace pellet production line.The equipments selection access the principle of advanced technology,reliable safety,established in civility and intredncing the imortant equipment.The coal powder making and spraying blowly technology of assistant system have high technalogical content and large hazard. So it is necessary to adapt the nitrogen protective equipment. Nowadays in industry production the environmental protection is an important content.The adaption of advenced enviremental prottction technique in designInsure circulationn using of most parts of materical and undischarge outside.The unreclaimable materical can discharge outside,but it must satisfy the envirenmental guideline.This article has high maneuverability, so it also is a guidance to building and production for pellet production line.
