Superior Dewatering Performance for Industrial Belt Presses
Skytech Ultrafab Belt Filter Cloth delivers outstanding solid-liquid separation efficiency in belt filter press applications across wastewater treatment, mining, paper, food processing, and chemical industries. Our precision-woven fabrics combine dimensional stability under tension, exceptional cake release, and resistance to blinding — ensuring peak dewatering performance on every shift.
What Is Belt Filter Cloth?
Belt Filter Cloth is a continuous woven fabric belt used in belt filter press (BFP) machines to mechanically squeeze water from sludge or slurry between two moving fabric belts and a series of rollers. The fabric provides the filtration medium through which filtrate passes while retaining the solids to form a dewatered cake that discharges from the belt end.
Features and Benefits
- Outstanding Cake Release: Optimised weave architecture and smooth surface treatments prevent blinding and ensure clean cake discharge at every cycle
- Dimensional Stability: Heat-set woven fabric maintains precise width and length under the high tension loads applied by belt press rollers
- Abrasion Resistance: Premium monofilament and multifilament yarns withstand continuous roller contact and mechanical wear
- Chemical Resistance: Polypropylene, polyester, and nylon options cover the full pH range from strongly acidic to strongly alkaline slurries
- Custom Weave: Plain, twill, and satin weave patterns tuned to the specific drainage rate and solids retention requirement of each application
- Edge Finishing: Heat-sealed or sewn edges prevent fraying and belt tracking problems during long production runs
