Bags
1. Specification
P84 is fiber made by Degussa Inspec Fibres, and is a high temperature polyimide fibre. P84 can withstand up to 260℃ in dry heat conditions or 195 where high moisture is present. Unlike most other fibres, P84 has a trilobal cross section which makes its particle capture and filtration efficiency very high. In some industries P84 is used in the filtration surface of other filter media to improve the filtration efficiency. In the cement industry, P84 is the most commonly used fibre where the off gases from the kiln or clinker cooler are high.

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.
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 |
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
Cage Diameter: customized
Star 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
