RF-B-HS-F
Filter belt for the use at mining sludge dewatering or paper industry
RF-B-HS-F Spiral Filter Belt: Heavy-Duty Dewatering for Mining and Paper Industry
High-Flow Spiral Belt Technology for Belt Filter Presses
The RF-B-HS-F is a premium heavy-duty spiral filter belt engineered for the most demanding applications in mining sludge dewatering and the paper industry. Unlike conventional woven filter belts, the RF-B-HS-F features a robust spiral construction that delivers exceptional resistance to creasing and abrasion — ensuring reliable, long-term performance on industrial belt filter presses. Optimized for high flow rates, this belt supports efficient thickening and filtration cycles even under continuous heavy-duty operation.
Key Features and Benefits of the RF-B-HS-F Spiral Filter Belt
- Outstanding Crease and Abrasion Resistance: The spiral design of the RF-B-HS-F fundamentally eliminates the risk of crease formation, a common failure point in traditional woven belts. Combined with its high abrasion resistance, this makes it the ideal choice for the mechanically aggressive conditions found in mining and paper production environments.
- High Flow Rates for Efficient Thickening: With air permeability values ranging from 3,200 to 5,600 l/m²/s, the RF-B-HS-F is optimized for maximum drainage performance. This ensures rapid water removal and efficient filter cake formation, reducing cycle times and increasing overall plant productivity.
- Full PET Construction for Durability: Both warp and weft are manufactured from high-quality polyester (PET), providing excellent dimensional stability, chemical resistance, and long service life — even in the wet and mechanically stressful conditions typical of mining and paper industry filtration.
- Available in Two Configurations: The RF-B-HS-F is available in two spiral variants to match your specific process requirements — a 3 round filler version for higher flow rates and a 5 round filler version for finer filtration.
Why Choose the RF-B-HS-F for Your Mining or Paper Industry Application?
When your process demands a filter belt that can withstand continuous mechanical stress, high flow volumes, and abrasive materials, the RF-B-HS-F spiral filter belt is the professional solution. Its unique spiral construction, combined with full PET material and two available configurations, gives plant operators the flexibility to fine-tune their filtration performance without compromising on durability or service life.
