Asphalt Mixing Plant Nomex Filter Bags Dust Collector Bag Filters
Quick Details:
Nomex filter bags is the best choice for Asphalt mixing plant
bag filter dust filtration.
Advantages:
1) Performs at high temperatures
Nomex Filter Bags can be used continuously at operating
temperatures up to 218°C (425°F) .
2) Good abrasion Resistant
Flex resistance of Nomex filter bag at room temperature is good,
about equal to that of polyester fibers; after aging at
temperatures of 121°C (250°F) and above its toughness if excellent.
Nomex filter bag should give more than three times the wear life of
polyester filter bags at 121°C (250°F) and above.
3) Good chemical Resistant
Nomex filter bag work well in acid environment, The
dust collector system should be warmed before putting on stream and
dried before being shut down to minimize chemical attack.
5) Dimensional Stability is well for Nomex filter bag
6) High temperatures
The most effective use of Nomex filter bag ,aramid filter bag is in
high temperature filtration systems where
effluent temperature are above 190 C degree or in
systems with surges over190 C degree. In hot gas filtration
systems, Nomex filter bag require less filter area, for equal
gas volume and efficiencies, than fiber glass.
Applications:
Nomex filter bag for higher temperature dust filtration ,widely
applied in Asphalt mixing plant ,cement Kiln smoke dust filtration
in cement plant ,steel melting furnace smoke filtration and so on .
NOMEX filter bag offer one of the best total economies in a
filtration system because of higher air to cloth ratios, higher
temperature capability, and a long working life.
