100% Polyester Fabric Sludge Dewatering Filter Mesh Conveyor Belt for Press
Polyester Filter Belts are specially designed woven mesh filter cloth for the belt press filters, it’s a circuit belt fabric connected by SS clipper seam to be able to work continuously.
The filter belts is a sturdy fabric made out by high viscosity polyester monofilament yarn on heavy-duty weaving looms and being heat set. PFM’s choose superior polyester monofilament yarn, weaving by advanced looms, excellent thermal treatment, all these makes our polyester filter belts in precise aperture, good transverse stability, lengthways flexibility, excellent mechanical strength and stability in shape and dimension.

Selection Guide(Physical Properties)
| Parameter | Typical Value/Range | Explanation |
|---|---|---|
| Material | PET Monofilament/Multifilament | Monofilament offers better airflow; multifilament provides higher solids retention. |
| Tensile Strength | Longitudinal ≥800~1200 N/cm | High-tension models require ≥1000 N/cm. |
| Elongation | ≤10% (operating condition) | Low elongation reduces belt-tracking issues. |
| Air Permeability | 5~12 m³/m²·h | Municipal sludge: 5~8 m³/m²·h; coarse-particle sludge may require higher values. |
| Pore Size | 30~150 μm | Activated sludge: 30~50 μm; mineral slag: 100~150 μm. |
| Thickness | 1.8~2.5 mm | High-pressure zones (>6 bar) recommend ≥2.2 mm. |
| Temperature Resistance | 90~120℃ (short-term) | Continuous operation temperature should be ≤80℃. |
Our Product Advantages
1. Cost-Effectiveness & Durability
Lower lifecycle cost vs. nylon/PTFE belts, with 8–18 months service life in municipal/industrial sludge.
High tensile strength (800–1200 N/cm) resists stretching, reducing downtime for re-tensioning.
2. Superior Chemical Resistance
pH stability (2–12): Ideal for most municipal wastewater (pH 6–8) and mild industrial effluents.
Anti-microbial: PET resists biological degradation in organic sludge environments.
3. Optimized Filtration Performance
Adjustable porosity: 30–150 μm pore sizes balance solids capture (≥95%) and dewatering speed.
High permeability (5–12 m³/m²·h): Faster water removal vs. multifilament belts.
Applicable Scenarios
1) The synthetic woven mesh filter belts are most widely used in dewatering and drying for municipal sludge, industrial slurries, and biologic sludge, and aid the mine tailing dewatering process for its capacity of continuous working and high efficiency.
2) Polyester mesh filter belt cloth is suitable for juice extracting and pressing from fruit and vegetables on the belt press filters, especially for apple, pear, thorn pear, ginger and other berries, nuts. Our woven mesh filter belts are always safe, robust and reliable, the special weave to get accurate pore size and sturdy surface combined which ensure optimum juice yield and dewatering result, the high-quality material and thermal treatment make the press belt fabrics in smooth running properties and good durability.
