Overview: FMC type compartmentalized pulse bag filter is a new type of compartmentalized pulse bag filter developed by our company through digestion and absorption of German * * * dust collectors with technological level in the 1990s. The dust collector adopts a 0.2-0.4Mpa pulse valve chamber by chamber spray cleaning method and 45 ° counter flow centrifugal technology. It adopts a fully automated control, compartmentalization, timing, and pressure difference cleaning method, which can collect 99.98% of dust from gas containing a large amount of ultrafine powder (particles ≤ 5 μ m content of 80% or more) and high concentration (1000g/Nm3). It has the characteristics of stable operation, high collection efficiency, easy maintenance, and long bag life, and is widely applicable. Fine powder collection in the field of deep processing of non-metallic ore ultrafine powder and various industries.
