Tensioned Polyurethane Filter Screen Mesh

Core Advantages

1. Tension-Mounted Installation for Flat and Stable Screen Surface

• Convenient Quick-Installation Structure: The high-elasticity tension hooks (or tension edges) on both sides of the screen panel can be directly attached to the dedicated support beams or tension plates of the vibrating screen. A single person can complete the installation and removal of an entire screen panel within a short time, greatly reducing equipment downtime for maintenance.

• Excellent Dynamic Stability: Through pre-tensioning technology, the screen remains tightly stretched under high-frequency vibration and material impact, effectively avoiding slack, collapse, or fracture caused by localized stress concentration, ensuring the continuity and stability of screening operations.

2. Superior Wear Resistance and Tensile Strength 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 3-10 times that of metal screens such as high-manganese steel. The pre-embedded steel wire rope framework, precisely treated, endows the screen with extremely high tensile strength and tear resistance.

• Significantly Reduced Maintenance Costs: Under high-wear conditions such as mining and coal washing, tension-mounted polyurethane screens offer an extremely long service life, greatly reducing the frequency of screen replacement and overall operating costs.

3. Efficient Anti-Blocking with Extremely High Throughput

• Excellent Self-Cleaning Capability: Polyurethane material possesses excellent elasticity, generating a strong “second harmonic” effect under high-frequency vibration. This high-frequency micro-vibration effectively shakes off adhering moist and sticky fine particles, fundamentally solving the problem of screen hole blockage.

• Optimized Opening Design: Screen openings are typically designed with an inverted taper (trapezoidal holes), wider at the top and narrower at the bottom, preventing material from getting stuck during screening. The effective open area is high, and throughput efficiency is increased by over 20% compared to traditional metal screens.

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 15-25 decibels compared to traditional metal screens, significantly improving the workshop working environment.

• Reduced Operating Energy Consumption: The overall weight is much lighter than metal screens of the same specification, significantly reducing the machine’s operational load and effectively saving electrical energy consumption during operation.

Technical Parameters

• Material: High-performance wear-resistant polyurethane elastomer + built-in high-strength steel wire rope / metal framework

• Installation Method: Tension hooks / tension edges on both sides (compatible with various hook-type vibrating screens and flip-flow screens)

• Screen Opening Specifications: 0.1mm – 50mm (slot, square hole, round hole, and irregular hole customization supported)

• Hardness Range: Shore 85A – 92A (balancing elasticity and wear resistance requirements)

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

Application Areas

Widely used in mining beneficiation (wet classification and dewatering of iron ore, gold ore, copper ore, etc.), coal washing (raw coal classification, clean coal desliming and dewatering), sand and gravel aggregate plants (mechanized sand classification and fine sand recovery), as well as solid-liquid separation and precision filtration operations in chemical, building materials, and environmental protection industries. Particularly suitable for various vibrating screening equipment with extremely high requirements for wear resistance, anti-blocking performance, and screening accuracy.
