Pin-Mounted Polyurethane Dewatering Screen Mesh / Panel

Core Advantages

1. Pin-Mounted Quick-Installation Design for Ultra-Fast Assembly and Maintenance

• Convenient Quick-Installation Experience: The screen panel is perfectly secured to the screen support beam through specially designed H-shaped interlocking pins or expansion anchor systems. Maintenance personnel simply align the panel with the pre-drilled holes and insert the locking pins to complete the installation. A single person can replace an entire screen panel within minutes, greatly reducing equipment downtime for maintenance.

• Stable Seamless Splicing: After pin fixing, multiple screen panels fit together perfectly, forming a continuous and flat screening surface. This tight modular splicing effectively prevents material jamming or leakage at the joints while ensuring the overall structural stability of the screening machine under high-frequency vibration.

2. Excellent Water Permeability and Anti-Blocking for Enhanced Dewatering Efficiency

• Efficient Self-Cleaning Mechanism: Polyurethane materials feature extremely low surface energy and an elastic recovery rate of over 95%. During operation, the screen surface generates a strong “second harmonic” micro-vibration effect, which effectively shakes off adhering moist and sticky fine particles, fundamentally eliminating screen hole blockage.

• Optimized Screen Opening Design: Screen openings are typically designed with an inverted taper (trapezoidal holes), wider at the top and narrower at the bottom. Water can pass through the slots quickly, while solid particles are less likely to get stuck. Combined with the excellent hydrophobic properties of polyurethane, it maintains extremely high throughput and separation accuracy even under challenging conditions with high moisture content.

3. Superior Wear and Impact Resistance for Extended Service Life

• Excellent Physical Properties: Made of premium wear-resistant polyurethane, its abrasion resistance is 3-5 times that of ordinary rubber and 5-8 times that of metal screens such as high-manganese steel. Under continuous scouring from highly abrasive materials like ores and coal, it resists cracking and structural damage, greatly reducing the frequency of spare parts replacement.

• Excellent Tear Resistance: High-strength steel wire or reinforcement frameworks pre-embedded inside the panel endow the screen with extremely high tensile strength and tear resistance, capable of withstanding the dual challenges of heavy material bed pressure and high-frequency vibration.

4. Vibration Damping, Noise Reduction, Lightweight and Energy Saving

• Excellent Shock Absorption and Noise Reduction: The inherent damping characteristics of polyurethane effectively absorb impact energy from material falling and machine operation, reducing operating noise by 10-20 decibels compared to traditional metal screens, significantly improving the workshop working environment.

• Reduced Operating Energy Consumption: With a density only about 1/7 that of steel, the panels are extremely lightweight. While ensuring high mechanical strength, they significantly reduce the machine’s operational load, effectively saving electrical energy consumption during operation.

Technical Parameters

• Material: High-performance wear-resistant polyurethane elastomer (polyester or hydrolysis-resistant polyether type available depending on operating conditions; steel-wire reinforcement can be embedded upon request)

• Installation Method: Pin-type插接固定 installation (compatible with various standard H-type interlocking pins or expansion anchor systems)

• Dimensions: Supports various industry-standard sizes (e.g., 305mm×305mm, 305mm×610mm, etc.), thickness typically 30mm – 50mm; customized non-standard sizes available per drawings

• Screen Opening Specifications: 0.1mm – 5.0mm (primarily supports high-precision slots, square holes, and custom anti-blocking shaped holes)

• Hardness Range: Shore 85A – 92A (balancing extreme anti-blocking elasticity and wear-resistant load-bearing requirements)

• Temperature Range: -30℃ to 80℃ (normal operating conditions; special formulations can withstand higher temperatures)

Application Areas

Widely used in mining beneficiation (tailings dry stacking and concentrate dewatering of iron ore, gold ore, copper ore, etc.), coal washing (coal slime dewatering, raw coal desliming), sand and gravel aggregate plants (mechanized sand washing and dewatering, fine sand recovery integrated units), as well as solid-liquid separation operations in chemical, building materials, and environmental shield slurry purification industries. Particularly suitable for various medium and heavy-duty high-frequency dewatering screens and sand washing equipment with extremely high requirements for convenient screen replacement and capable of processing high-moisture-content materials.
