Tufflex Screen Cloth for Sticky Wet Material
The Core Problem
Sticky and wet material causes screening media to fail in predictable ways: surface blinding, aperture pegging, wire wear, and reduced effective open area. TUFFLEX-TYPE SCREEN CLOTH
The solution depends on which problem you actually have — not on the product name.
The Five Media Options
1. Tufflex-type PU-coated wire or synthetic rope
Smooth coated surface + tensioned wire-based structure. Best for wet aggregate and damp mineral material where conventional cloth experiences both wear and buildup.
2. Flexible anti-blinding cloth
Independently moving wires or flexible rubber surface designed specifically to release lodged material. Best for fine or damp material that repeatedly blinds conventional wire cloth.
3. Modular polyurethane panels
Molded apertures, wear-resistant surface, replaceable modules. Best for wet abrasive duties where modular installation is compatible. Check open area and mounting before assuming fit.
4. Polyurethane flip-flow media
Elastic surface stretches and relaxes to release trapped particles. Best for difficult fine screening where the plant can accommodate a compatible flip-flow system.
5. Conventional woven wire cloth
High open area and familiar tensioned installation. Remains appropriate for free-flowing material where capacity and sizing are priorities.
What PU Coating Actually Does
A polyurethane surface reduces the tendency of some materials to adhere. It does not eliminate blinding.
Clay-rich feed, high moisture levels, near-size particles, and unsuitable operating conditions can still cause blockage. The coating helps — it does not guarantee.
Six Selection Steps
Identify material and moisture conditions — wet, damp, or intermittently dry; clay content; abrasiveness; sharp particles; seasonal variation
Determine the blockage type — blinding (surface accumulation) vs pegging (particles lodged in apertures)
Confirm aperture size and shape — balance cut size, effective open area, and tendency to blind or peg
Review wear and impact conditions — examine feed end, central deck, and discharge end for localized wear
Check the tensioning system — deck dimensions, hook type, tension arrangement, support bars, clamping components
Evaluate total operating cost — throughput, product consistency, cleaning frequency, replacement intervals, downtime, cost per tonne
Failure Analysis
| Problem | Possible Cause | Recommended Solution |
|---|---|---|
| Surface blinding | Sticky fines, clay, high moisture | Consider Tufflex-type cloth or anti-blinding media |
| Aperture pegging | Near-size particles lodged | Review aperture geometry, consider anti-blinding cloth |
| Wire wear | Abrasive feed | Tufflex-type PU-coated cloth |
| Localized wear at feed end | Concentrated impact, poor distribution | Review feed arrangement |
| Coating damage | Aggressive cleaning method | Use approved cleaning procedures |
| Persistent blockage despite media change | Process problem | Investigate feed moisture, distribution, screen settings |
Case Study
Customer Type: Sand and gravel washing plant
Ore Type: Wet sand with clay content
Operating Conditions: Continuous wet screening, moderate abrasion
Problem: Conventional woven wire cloth blinded frequently, required manual cleaning every shift, and wore through at the feed end within 6–8 weeks.
Solution: Converted to Tufflex-type PU-coated wire cloth with matched aperture and hook configuration.
Result: Manual cleaning frequency reduced by approximately 50%, wire wear reduced significantly, and service life increased to approximately 4 months.
FAQ
What is the best screen cloth for wet and sticky material?
Depends on the feed and screening objective. Tufflex-type PU-coated cloth suits adhesion and wear. Anti-blinding cloth suits fine persistent blinding. Modular PU panels suit compatible wet abrasive duties.
Does PU-coated wire cloth prevent blinding completely?
No. PU coating reduces adhesion but does not eliminate blinding. Clay-rich feed, high moisture, near-size particles, and incorrect screen operation can still cause blockage.
Is Tufflex-type cloth better than conventional wire mesh?
Neither is universally better. Conventional wire offers high open area; Tufflex-type combines wire structure with PU surface. The better choice depends on cut size, wear, blockage history, and operating cost.
Should I use PU panels or Tufflex-type cloth?
PU panels when molded construction and modular mounting suit the application. Tufflex-type cloth when a tensioned wire or rope format is required. Verify deck compatibility before ordering.
What information is needed to select a replacement?
Screen model, deck dimensions, aperture size and shape, hook type, feed material, moisture conditions, description of the problem, and photographs of the existing cloth.
How do I tell blinding from pegging?
Blinding = material accumulates on or covers the surface. Pegging = particles lodged in apertures. Sticky deposits need a different approach from near-size particles.
Why does my cloth blind even with a PU coating?
PU coating reduces adhesion but does not eliminate blinding. Clay, high moisture, near-size particles, and incorrect operation can still cause blockage.
When should I consider flip-flow media?
When fine, sticky, or moisture-rich material causes persistent blinding and the plant can accommodate a compatible flip-flow screen system.
How do I evaluate total operating cost?
Throughput, product consistency, cleaning frequency, wear and replacement intervals, labour, downtime, and total screening-media cost per tonne processed.
What is the most common selection mistake?
Selecting by product name instead of diagnosing the blockage type. Surface blinding, aperture pegging, wire wear, and impact damage require different solutions.
Conclusion
The best Tufflex-type screen cloth for sticky and wet material is the one that matches the feed condition, aperture requirement, mounting system, and wear mechanism.
PU-coated wire or rope cloth is a useful option when a smooth screening surface, tensioned construction, and resistance to wear and buildup are important. For persistent fine-material blinding, dedicated anti-blinding media or flip-flow systems may be more appropriate. Modular PU panels provide another option for compatible wet and abrasive duties.
Start by identifying the actual problem, confirm the required aperture and deck arrangement, and compare suitable media under realistic operating conditions.
