Acid Resistant Custom Fabricated Spiral Weave Screen Belting, High Wearing- Resistant Spiral Belt, Monofilament Filter Belt, Monofilament Filter Fabric, Polyester Filter Fabrics
Made by World-Class Heatsetting Tables and ISO 9001 Quality Assurance System
Spiral filter fabrics are made of abrasion resistant PET. They contain a strong spiral seam, which has the same tensile strength as the fabric. In comparison with the clipper seam on woven fabrics, the seam on spiral fabrics has a longer service life and does not fail prematurely. It is no longer the weak point of the belt.
Dewatering properties of the fabric are given by its air permeability, which can be adjusted by inserting a suitable type of filler yarns inside the spirals. We offer spiral fabrics in the range of air permeability form 250 to 900 CFM.
Spiral fabrics are especially suitable for dewatering of fibrous material (paper sludge, pulp) and sludges with a high content of inorganic particles (e.g. mining sludges), but they can also be used for dewatering of treated municipal sludge. If the sludge has a high content of organic particles or if it is sticky and muddy, there is a risk of spiral fabric blinding.
Benefits:
Long service life
Suitable especially for machines where belt deformation often occurs
Abrasion resistant design
No problems with the seam
Smooth adhesive treated belt edges
Suitable for fibrous sludges
Examples of Application:
Dewatering of pulp and paper sludge
Dewatering of industrial and municipal sludge in belt filter presses
Dewatering of mining and abrasive sludge
Thickening of sludge in gravity thickeners
Forming belt for production of MDF boards
Conveyor belts
