Description

Polyester Spiral Belt as Filtration Textiles for Fine-Elements Catching, Spiral Belt for Drying in Paper Mill

Quality Assured by ISO 9001 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
