Type: bag ash collecting hopper→pneumatic fluidized conveying→large ash collecting bin suction and discharge truck transportation; the pneumatic conveying method of blast furnace gas dust removal ash has obvious advantages than the mechanical conveying method, such as less investment and transportation.


Large conveying capacity, long conveying distance, free layout, operation, and good air tightness, which can avoid gas leakage and secondary dust during the process of unloading and conveying ash. Large blast furnaces should choose pneumatic conveying.

And nowadays, blast furnace adapts FMS filter bags, it can usually last 3 years in working life.
