Polyurethane dewatering screen mesh revolutionizes industrial solid-liquid separation with exceptional durability, precision screening, and minimal maintenance. Engineered for vibrating screens in mining, aggregate processing, and wastewater treatment, our mesh excels in dewatering coal slurries, mineral concentrates, and tailings while resisting abrasion, corrosion, and material blinding. Unlike metal screens, polyurethane’s elasticity enables secondary vibrations, boosting efficiency by 30% in moisture reduction and recovery of fine particles .

Key Specifications & Dimensions

Customizable for linear, circular, or high-frequency vibrating screens:

1. Materials & Thickness
   - Polyurethane Elastomer:
      - Hardness: 45–95 Shore A (Type-A/B grades for varied impact resistance)
      - Standard Thickness: 30–60 mm (reinforced with steel frames for heavy-duty operations) .
   - Aperture Types & Sizes:Table: Standard Configurations

Hole Pattern	Aperture Range	Primary Applications
Square Slots	0.1–2.5 mm	Coal dewatering, fine sand recovery
Longitudinal Slots	0.25–160 mm	Iron ore classification, tailings dry stacking
Conical Holes	1–50 mm	Anti-blinding gravel dehydration
Custom Sieves	Client-specified	Specialty mineral processing

Note: Slot lengths for square/longitudinal designs: 14–16 mm; conical holes prevent pegging by enabling self-cleaning .
2. Panel Sizes & Compatibility
   - Modular Panels: 300 × 1,000 mm (standard inlay/bolt-fastened types)
   - Full-Screen Assemblies: Up to 3,500 × 6,000 mm (tailored to fit linear/banana vibrating screens)
   - Open Area: 15–40% (optimized for flow rate vs. dewatering efficiency) .

Performance Advantages

1. Extended Service Life:
   - 5× longer lifespan than rubber screens and 3× longer than steel mesh due to ultra-high wear/impact resistance .
2. Zero Blindness & High Output:
   - Conical aperture design prevents material clogging, maintaining ≥95% screening accuracy even with sticky ores .
3. Noise & Vibration Reduction:
   - Polyurethane absorbs 50% more operational vibration, reducing noise pollution and screen-frame fatigue .
4. Corrosion Resistance:
   - Immune to oil, water, and chemical erosion—ideal for saltwater mineral processing or acidic tailings .

Industry Applications

- Coal Washing: Square-slot screens (0.5–1.5 mm) reduce coal slurry moisture to ≤15% for efficient transport .
- Mineral Recovery: 0.25-mm longitudinal slots capture gold/copper fines from slurry, boosting yield by 20% .
- Tailings Management: 30-mm-thick panels with conical holes dewater mine tailings to solid-state for dry stacking .
- Sand/Aggregate Processing: 2.0-mm slotted screens achieve <10% residual moisture in construction sand .

- Aperture Optimization: CAD-based designs for specific materials (e.g., iron ore vs. lithium brine).
- Connection Systems: Bolt-fastened, bead-connected, or inlay mounting for quick replacement (<30 mins downtime) .
- Surface Treatments: Anti-static coating for coal applications; UV stabilization for outdoor use.
