Polyester Spiral Belt for Filtration
- PRODUCT DETAIL
Polyester Spiral Belt for Filtration and Washing of Coarse Grained Slurries, Spiral Belt for Urban Waste Water Treatment Plant, Monofilament Filter Belt, Monofilament Filter Fabric, Polyester Filter Fabric
Made by World-Class Heatsetting Tables and ISO 9001 Quality Assurance System
Polyester spiral belts 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 belts has a longer service life and does not fail prematurely. It is no longer the weak point of the belt.
Spiral belts 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.
