The polyester spiral mesh belts have a spiraled continuous and seamless screen structure, which is ideal for applications in which a seam would be unmeet due to mechanical loads. Meanwhile, the unique spiral linked weave type makes the polyester spiral mesh belts flexible in warpage, and the heat-setting treatment ensures the spiral belts durability and a long, productive life without deformation, easy to install, clean and maintains.

This kind of synthetic spiral fabrics are widely used as filter belts, dryer screen belts or conveyor belts in dewatering processes with fibrous products, or for industry sludge dewatering and drying, nonwoven forming, and thermal applications include drying of veneers, manufacture of gypsum plasterboard or for multi-stage dryers in the foodstuff processing etc.

Bonfilt’s polyester spiral mesh belts can be made of 100% Polyester, or anti-hydrolysis Polyester for high temperature and high humidity, or 100% PPS for high temperature 150-240°C working condition, other kinds of material can be customized for antistatic, dirt-repellent, or enhanced abrasion-resistance performance etc.

Various types in different yarn diameter 0.5mm-1.1mm, small, medium and large spiral rings, flat or round yarn, filled or unfilled are all available to achieve optimal air permeability rates, tracking stability, high throughput rate, and excellent filtration efficiency.
