The dust catching system of the sand drying section on dry mortar production line includes two levels, the first level uses the cyclone dust catcher and the second level uses the pulsed bag style dust catcher. The dedusted powders will be recycled back to the sand silo by the spiral conveyer. The other dust positions on the production line are all equipped with bag style dust catcher. The structure of the whole system is simple and tight, and it is also easy in installation and convenient in maintenance. Its dedusting efficiency can reach 99.9%. The discharging of the powder dust is fully complied with the national standard.
Pulse dust collector is a high efficienfy dust collector. PPCA series of large pulse length bag filter is our technical personnel from domestic and foreign advanced technologies based on thermal power plant ,cement plant , metallurgy industry, chemical industry, the characteristics of smoke, for the successful development of power plant boiler, cement rotary kiln, steel mills, coke oven blast furnace, and other special high long bag filter.It combines the sub-room cleaning and the characteristics of pulse cleaning, to overcome the general sub-room cleaning and the general lack of intensity pulse cleaning dust and then attached to the shortcomings of the bag and longer air force into full play the role of cleaning. It is s a high collection efficiency, stable, reliable performance, easy maintenance of large bag filter dust removal equipment.
