PTFE Dust Filter Bags And Cages PTFE Star Bag And Star Cage Bag House PTFE Dust Collect Round Bag And Cage
Bags
1. Specification
Polytetrafluoroethylene is made from the monomer tetrafluoroethylene by free radical vinyl polymerization. PTFE is perhaps the most inert, chemically resistant, and temperature resistant polymer used in industrial filtration. Its characterizes are as follows:
- ) The continuous working temperature is 250℃, the instantaneous temperature is 280℃.
- ) Totally resistant of PH and oxidation, hardly inflammable
- ) One and only not aging
- ) Meet the worst condition, has the extremely long service life, usually three years
100% PTFE bag is mainly used in chemical industry, waste incineration, high temperature resistant liquid filtration, keeps good chemical stability in the complex condition.
Finish Treatment: Singeing, Calendering, Heat Setting, Anti-static, Water&Oil Repellent, PTFE Membrane, PTFE Impregnation and so on
Bag Style: round bags, oval bags, 8 and 12 star/ pleats star bags
Bag Size: it is up to the CPO and installation and customized
Bag Head: seal cuff / groove snap / felt strip, bead cuff/ steel strip, etc can be chosen
Bag Body: Sewing or Hot sealing
Bag Bottom: Single or double bottom, with reinforcement or without reinforcement

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
4. 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
Cage Diameter: customized
Cage Finish Treatment: silicon coating, zinc coating, electrophoresis coating
Cage Head: normal top cap, venturi top cap, split top (Mikropul) cap, wires bent (hook) top, enlarged top ring etc
Cage Connection: cages were too long or top space of bag house was not enough, we suggest make cages in sections with joint like below
