SS304 SS316 8 Ray Stainless Steel Filter Cages 120mm

304SS 8 Ray Star Filter Cage Stainless Steel Pleat Cage 120mm 316SS Spider Cage Bag House Cage
 
1. Specification
Star cage, also names pleat cage, spider cage, is the bone and framework of bag, supporting the bag running, is special designed and made for star bag. Star Cages are welded by special supporting rings (Spiders). We are specialized in Star Cages design, develop and process. 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.

The pleat (star) filter bag has an inside support construction, star cage. This star (spider) cage can be made of mild steel, stainless steel, galvanized wire. The star/pleat/spider cage has wires running parallel down the length of the cage to form the point of each star, these rods, two for each ray, are connected to center star/pleat shapes (spider shape supporting ring, called spider for short), which are placed at regular intervals down the length of the star (spider) cage. The rods, forming the tips of the rays, are set one each side of the star ray close to the point. There is space between them that prevents a sharp star point, in order to reduce mechanical abrasion to the filter material. The filter star/pleat bag touches the cage only along the edges of these to rods, which also minimizes mechanical damage and allows the pleat/star bag to be used fully as a filtration surface. The star/spider cages can also be constructed of extruded aluminum or plastic profile. The profiles have an indentation at each star point, again so that the filter material is held on two round edges instead of having a sharp point. The star/pleat (spider) cages can also be made out of welded wire or out of a star pipe construction.

3. Advantage

The Star filter bags extend the filter surface, the increaing filter area compared to ordinary round ones is below,

Filter area increasing (%)

So
• longer bag service life

• increase the air volume of existing dust collectors to increase production capacity

• lower emission

• reduce energy consuption

• reduce operation cost

• reduce pressure drop

• lower pulse jet pressure and frequence

• small bag house and building area

• lower the filter velocity

 
4. Some Endusers

Our Star Cages are used worldwide, there are about our 400 thousand star cages running everyday, such like Kitmat Smelter Modernization Project (Rio Tinto Inc, Canada), Aluminerie De Baie Comeau (Alcoa Ltee/Ltd, Canada), Dubai Aluminium Company Ltd (Alstom, Dubai,EGA), Nordural Century Aluminium (Iceland), Trimet Aluminium SE (German) and so on.
