Sintering annular cooler is one of the main equipment in metallurgical sintering process, which is used to cool the hot sinter discharged from the sintering machine, recover the residual heat, aiming to achieve the suitable transportation of ore materials.
The new generation of water sealed blast annular cooler (520㎡ multi-functional and efficient sintering annuar cooler) produced by NHI has been put into use in the second phase sintering project of Lianfeng iron and steel company in May 2015. From the current situation, the structure is stable, high sealing, high waste heat recovery efficiency and cooling efficiency which are much higher than the old blast annular cooler.
The rotating body of the this sintering annular cooler is made up of several sector integral frames, each frame is equipped with several trolleys with reliable gravity reversal, which solves the problem of insufficient rigidity in the rotating process of the old annular cooler. The seal between the revolving body and the air box adopt the composite seal structure, which greatly reduces the air leakage rate. In case that some fans of them have power reduction, the annular cooler is also meeting the requirement of operating, which is not only considered environmental protection but also considered energy-saving.
