The sinter plant fan is of steel plate fabricated casing with steel piping supports inside thecasing and formed steel reinforcement outside the casing, which is reasonable in constructionand characterized by good rigidity.The casing is in the same centre height with the bearingpedestals, which is easy for installation,ess influence from thermal expansion and excellencein stability.Computer software with finite elementmethod is adopted to calculate the critical speed ofrotors and impeller strength,resulting in accuracy andreliability and thus the stable and safe operation oftrain is ensured. Simulation design with high efficientbasic stage model leads reliable performance andwider operating range. Advanced anti-erosionmeasures are taken for impellers and casinginternals, while increasing the
