Description
Woven/Spiral Belts for Process Filtration and Pollution Control, Spiral Belt for Drying in Paper Mill
Made by Modern 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.
Dewatering properties of the fabric are given by its air permeability. Keylife offers spiral fabrics in the range of air permeability form 300 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.
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
