Polyurethane Screens: Industry-Specific Solutions for Efficient Screening & Cost Savings

1. Mining Industry: Boosting Primary Crushing Efficiency

Challenge: Screening high-hardness granite (Mohs 6–7) with 8% mud content.
Solution:

Design: 12mm trapezoidal holes (top: 12mm; bottom: 10mm), 10mm thickness, 85A hardness, 45% open area.
Results:

92% penetration rate; only 2 cleanouts/month.

7-month lifespan (30% cost savings vs. rubber screens).

Trapezoidal holes prevent mud clogging; 85A hardness resists granite wear.

2. Manufactured Sand: Fine Sand Recovery & Dewatering

Challenge: Recovering 0.3–5mm sand with ≤12% moisture and ≥85% recovery rate.
Solution:

Design: 1mm square holes, 5mm thickness, 80A hardness, 55% open area.
Results:

88% fine sand recovery; 10% moisture (meets concrete standards).

15% faster dewatering than stainless steel screens.

3. Wastewater Treatment: High-Efficiency Impurity Removal

Challenge: Filtering fibrous impurities (e.g., plastics) in pH 7.5 wastewater.
Solution:

Design: 25mm circular holes, 15mm thickness, 90A hardness, 35% open area.
Results:

98% impurity interception; 12-month lifespan.

Tear-resistant ribs prevent fiber entanglement.

4. Construction Waste: Handling Irregular Materials

Challenge: Screening mixed debris (concrete, bricks) with varying sizes.
Solution:

Design: 20mm round holes, 12mm thickness, 90A hardness, 40% open area.
Results:

85%+ screening efficiency; 8-month lifespan.

Circular holes reduce clogging vs. metal screens.

5. Metallurgical Industry: Corrosion-Resistant Slurry Screening

Challenge: Processing acidic slurries (pH 4–6) with 0.1–1mm particles.
Solution:

Design: 5mm square holes, 8mm thickness, 85A hardness, antioxidant-modified.
Results:

2x lifespan in corrosive environments vs. standard screens.

50% open area balances speed and strength.

Conclusion

HT Polyurethane screens deliver industry-specific advantages, from clog resistance in mining to corrosion protection in metallurgy. By matching screen specifications (aperture shape, hardness, thickness) to material properties, operations achieve higher efficiency, longer service life, and significant cost reductions.
