◆ rational combination of airflow, use smooth intake flow, downstream filter, so that dust coagulating sedimentation also has a role in filtering state, reduce the bag load and pulse frequency. ◆ bag port with flexible expansion ring seal, convenience and good dust tight, disassembly. Frame for resistance welding, the outer surface smooth and no welding marks, solve the bag and frame abrasion mine removal equipment, bag and long service life. ◆ choice of performance based on environmental conditions, different sizes of filter, dust removal equipment running resistance stable prices, low energy consumption and dust removal efficiency of more than 99.9% of the working principle filter dust collector means a cloud of dust containing pores through the filter layer, the air in the dust filter layer blocking particles are trapped down, in order to achieve solid separation equipment. Filter means comprises a dust bag filter and a particle filter layer, the former is usually an organic fiber or inorganic fiber fabric layer made of bag filter as the latter use of a filter layer of particles of different sizes, such as quartz sand, river sand, ceramic, slag and other components. Accompanied powder duplicate attached to the bag outer surface, the powder layer constantly thickening, bag filter resistance value also increased; pulse valve diaphragm issued a directive, at around submerged pulse valve is open, the compressed high-pressure gas within the package air links, if there is no dust or small a certain extent, mechanical cleaning work will stop working. Dust accessories, dust, provided by the State Mining Equipment Co., Ltd. Weifang country special. Special Mining Equipment Co., Ltd. Weifang States (www.sdguote.com) strong, credible, Shandong Weifang crushing grinding equipment industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the country into the brilliant special and you work for a better future!
