Rotary kiln for iron ore pelletizing

 

Rotary kiln for iron ore pelletizing Description: 
With the rise of almost demanding requirements for fine material of modern blast furnace, as well as the rise of short process of iron and steel smelting , the role of pellets in the steel industry is even more important, has become an integral part of high-quality metallurgical furnace burden. Adopting grate - kiln process to produce oxide pellets, in order to ensure reliable technology, equipment running well, production stability, in addition to iron-containing raw material used, the binder and coal powder should meet the technical requirements, the most critical is the reasonable control of the grate -kiln thermal system. Over the last decade, our company's traveling grate - rotary kiln engineering technology takes the leading position in the world. The engineering application ores involve mineral magnetite, vanadium-titanium magnetite, hematite, limonite and so on. Iron pellets rotary kiln is mainly composed of cylinder, kiln head,sealing device for kiln tail, gearing, riding wheel support device (including gear wheel), slip ring devices and other components. Outside the cylinder of feed end and discharge end, with cold air cooling to prevent burning off kiln cylinder and necking rings and sealing scales.
