Tufflex-type screen cloth is a screening medium made with polyurethane-coated wire or synthetic rope. The design combines a wire-based structure with a polyurethane surface, offering customizable configurations. It is one of several media options for wet and sticky screening.
Working Principle
Sticky screening problems rarely have a single cause. Material adhesion, aperture blockage, abrasion, and the need for adequate open area all influence performance.
A polyurethane surface reduces the tendency of some materials to adhere. The underlying wire or rope construction provides screening openings while allowing the cloth to be tensioned using a compatible deck arrangement.
Benefits
Reduced adhesion. PU coating limits material buildup.
Wear resistance. Coating protects the wire structure.
Tensioned format. Compatible with hooked-edge decks.
Customizable apertures. Wire diameter, aperture size, and configuration can be matched.
Balance of open area and wear life. Wire openings with surface protection.
Applications
Tufflex-type cloth is a candidate for wet aggregate, damp mineral material, and applications where conventional WIRED & STEEL SCREEN MESH experiences both wear and material buildup.
Screening sits between CRUSHING and GRINDING in the comminution circuit.

Selection Guide
Six steps determine the correct media:
-
Identify material and moisture conditions — wet, damp, or intermittently dry; clay content; abrasiveness; sharp particles.
-
Determine the blockage type — blinding vs pegging.
-
Confirm aperture size and shape — balance cut size, open area, and blinding tendency.
-
Review wear and impact conditions — examine feed end, central deck, and discharge end.
-
Check the tensioning system — deck dimensions, hook type, tension arrangement, support bars.
-
Evaluate total operating cost — throughput, product consistency, cleaning frequency, replacement intervals, downtime, cost per tonne.
Procurement Guide
Required information: screen manufacturer and model, existing screen-cloth dimensions, required aperture size and shape, hook type and tensioning arrangement, material type and moisture conditions, description of the current problem, photographs of the existing cloth and worn or blocked areas.
Drawings needed: screen-cloth outline with hook detail, deck layout, and OEM part number where available.
Material selection: request PU coating specification, wire or rope diameter, aperture tolerance.
MOQ: typically per panel or per deck set.
Lead time: commonly 2–4 weeks for standard configurations.
Packaging: crated flat to prevent deformation.
Shipping method: sea freight for volume; air freight for breakdown-critical replacement.
Inspection standards: dimensional check, wire diameter verification, aperture measurement, coating inspection, hook integrity check.
Supplier Evaluation Checklist:
-
Can the supplier manufacture according to drawings?
-
Can the supplier provide material reports?
-
Can the supplier support OEM replacement?
-
Does the supplier have export experience?
-
Can the supplier provide wear-life recommendations?
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 |
| Cloth movement | Incorrect tensioning or worn hooks | Verify installation and support condition |
| Persistent blockage despite media change | Process problem | Investigate feed moisture, distribution, screen settings |
Maintenance Guide
Daily inspection: check for visible blinding, pegging, and material buildup.
Weekly inspection: examine high-wear zones, hook condition, and tension.
Monthly inspection: measure aperture condition and record wear patterns.
Replacement timing: based on measured wear and screening performance, not calendar intervals.
Spare parts inventory: hold one deck set plus high-wear zone panels.
Downtime reduction: correct media selection reduces cleaning frequency.
Preventive maintenance: use cleaning procedures approved for the specific media.
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.
Results are indicative of typical performance and depend on ore characteristics, deck configuration, and operating discipline.
FAQ
Question: What is the best screen cloth for wet and sticky material?
Answer: The best choice depends on the feed and the screening objective. Tufflex-type polyurethane-coated wire cloth is worth evaluating when surface adhesion and wear are concerns. Dedicated anti-blinding media may be more suitable for persistent fine-material blockage.
Question: Does polyurethane-coated wire cloth prevent blinding completely?
Answer: No. A polyurethane-coated surface may help reduce adhesion, but blinding can still occur when the material contains sticky fines, clay, or other challenging particles.
Question: Is Tufflex-type screen cloth better than conventional woven wire mesh?
Answer: Neither option is universally better. Conventional wire cloth can offer high open area, while Tufflex-type cloth combines a wire-based structure with a polyurethane-coated surface. The better choice depends on cut size, wear conditions, blockage history, and operating cost.
Question: Should I use polyurethane panels or Tufflex-type screen cloth?
Answer: Consider polyurethane panels when their molded construction and modular mounting arrangement suit the application. Consider Tufflex-type cloth when a tensioned wire or synthetic-rope format is required. Verify screen-deck compatibility before ordering either type.
Question: What information is needed to select a replacement screen cloth?
Answer: Provide the screen model, deck dimensions, aperture size and shape, hook type, feed material, moisture conditions, and a description of the existing problem. Photographs of the installed cloth and wear patterns help.
Question: How do I tell the difference between blinding and pegging?
Answer: Blinding occurs when material accumulates on or covers the screening surface. Pegging occurs when particles become lodged in apertures. Sticky surface deposits may call for a different approach from near-size particles wedged inside openings.
Question: Why does my screen cloth blind even though it has a polyurethane coating?
Answer: A polyurethane coating reduces adhesion tendency but does not eliminate blinding. Clay-rich feed, high moisture, near-size particles, and unsuitable operating conditions can still cause blockage.
Question: When should I consider flip-flow media instead?
Answer: Flip-flow media is relevant when fine, sticky, or moisture-rich material causes persistent blinding and the plant can accommodate a compatible flip-flow screen system.
Question: How do I evaluate total operating cost?
Answer: Consider throughput, product-size consistency, cleaning frequency, wear and replacement intervals, labour and maintenance requirements, downtime, and total screening-media cost per tonne processed.
Question: What is the most common selection mistake?
Answer: Selecting a screen cloth by product name rather than diagnosing the actual 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.
Polyurethane-coated wire or synthetic-rope cloth is a useful option when a smooth screening surface, a tensioned construction, and resistance to wear and material buildup are important. For persistent fine-material blinding, dedicated anti-blinding media or flip-flow systems may be more appropriate.
Start by identifying the actual problem, confirm the required aperture and deck arrangement, and compare suitable media under realistic operating conditions.
