PPS Dust Filter Bags And Cages Bag House PPS Star Bag And Cage Dust
Collector PPS Bag And Cage
Bags
1. Specification
PPS(polyphenylene sulphide) polymer is formed by reaction of
sulphur with dichlorobenzene. PPS has both high temperature
resistance (190℃) as well excellent acid and alkali resistance, although it can be
degraded in highly oxidative environments. PPS fiber needle felt is
made of imported PPS fiber which produced by Japan, it is the
leading varieties of the high temperature fiber material, PPS
filter bag perform excellent in the application of the following
situations.
1) The working temperature is up to 190℃,short term working temperature 210℃, the melting point of 285℃, the limit oxygen index 34-35
2) The oxygen content with 10% or below can be used
3) The place of flue gas containing moisture
PPS has the strength to keep the integrity and intrinsic chemical
resistance, can maintain a good performance in the bad
environments, and achieve the ideal life. PPS bag is the ideal
material of filter coal boiler, incinerator ash, dust processing
and others pulse dust collectors.

Cages
1. Specification
Cages are frameworks for bags, which is the bone of bags and
supports the bags running. Both bags and cages are the most
important element for bag houses. Star Cages are welded by special
supporting rings (Spiders). We have own stretch line, cut line,
weld line, coating line and check equipment. Providing a wide range
of star filter cages for bag house collector, which improve the
performance, efficiency and bottom line of the bag house dust
collector and flue.
2. Procedure of cage making
| 1 | stretch line | streth 6 or 6.5 raw wire to roll diameters wires for cages,
normally 3mm, 3.5mm and 4mm, |
| 2 | cut line | cut roll wires to fixed length based on cage sizes |
| 3 | weld body | weld vertical wires and suppoting ring together |
| 4 | weld top and bottom cap and venturi | weld top and bottom cap to cage, venturi if necessary |
| 5 | coating | silicon or zinc coating if necessary |
| 6 | inspect and fix | inspect weld loose, burs, coating etc and fix |
| 7 | pack | put cages into steel crates |
3. Cage Style: round cages, oval cages and pleats star cages
construction of cages
| style | Vertical Wire QTY | Diameter of Wire | Supporting Ring | Top Cap | Bottom Cap | Connection |
| round cage | 8-24 | 4 / 3.5 /3.2 /3 | wire, round | optional | weld, crimp, wire bent | twist lock, sure lock, finger lock |
| oval cage | 10, 14 | 4 | wire, oval | oval | weld | slide lock |
| star/ pleat cage | 8,10, 12, 16 | 4 | press, wire | optional | weld or wire bent | global joint |
Optional Material: carbon steel, galvanized wire, stainless steel
