Revolutionizing Dry Screening: Polyurethane Tendon Screens Deliver Unmatched Durability for Mining Operations

In the demanding world of mining dry screening operations, traditional metal screens often fall short due to rapid wear, frequent tearing, and persistent clogging—issues that drive up maintenance costs and cripple productivity. Enter polyurethane tendon screen panels, a groundbreaking solution engineered to overcome these challenges through material innovation, structural reinforcement, and optimized design.

1. Material Mastery: 2X Extended Wear Life

   • Elastic Polyurethane Matrix (Shore 85-90A) absorbs 30% of impact energy, reducing localized wear by 40% versus manganese steel.
   • Wear-Resistant Particle Infusion (20-30% silicon carbide/aluminum oxide) boosts surface hardness to Shore 95A (HRC45 equivalent), slashing wear loss by 50% compared to standard screens.

2. Structural Integrity: 3X Tear Resistance

   • Embedded Fiberglass/Nylon Tendons (1-2mm thick) enhance tensile strength to 25-30 MPa and tear strength to 80 kN/m.
   • Seamless One-Piece Molding eliminates weak joints, reducing monthly tear rates to just 0.5%.

3. Anti-Clogging Design: ≤8% Blockage Rate

   • Trapezoidal Apertures (e.g., 15mm top/12mm bottom) prevent particle wedging, cutting clogging by 60% versus square holes.
   • Elastic Self-Cleaning Vibration (0.5-1mm amplitude) reduces dust adhesion from 15% to below 5%.

4. Operational Efficiency: Quantifiable Results

   • 2X lifespan over traditional screens.
   • $36,000+ savings in three months (case study data).
   • 18% output boost with near-zero downtime.

Ideal for processing abrasive ores like granite and iron, these screens combine elasticity, wear resistance, and smart geometry to deliver:

• Lower maintenance costs (eliminate manual cleaning).
• Higher throughput (consistent open area ≥92%).
• Quieter operation (5-10 dB noise reduction).
