Polyurethane Anti-Clogging Screen Panel with Rail Mounting

Core Advantages

1. Innovative Anti-Blocking Design with Efficient Self-Cleaning

• Secondary Vibration Self-Cleaning: Utilizing the high elasticity of polyurethane material, the screen strips produce slight micro-vibration (second harmonic) under high-frequency vibration, effectively shaking off moist fine particles adhering to the screen opening surface, keeping the screen surface continuously clear.

• Anti-Blocking Opening Design: Adopting special opening designs such as inverted tapered holes and variable cross-section slots, particles at the limit size are less likely to get stuck in the screen openings, significantly reducing the blockage rate, with screening efficiency increased by over 20% compared to traditional screens.

2. Rail-Mounted Quick-Installation with Seamless Splicing

• Ultra-Fast Assembly: The pre-formed standard slots on the sides perfectly match the screen rails, requiring no additional fasteners such as bolts or clamping bars. A single person can complete the replacement of one screen panel within minutes, greatly reducing equipment downtime for maintenance.

• Seamless Splicing: High-precision mold forming ensures tight splicing between panels, eliminating material jamming and leakage, ensuring continuity and stability of the screening process.

3. Superior Wear Resistance and Vibration Damping for Quiet and Environmentally Friendly Operation

• Extended Service Life: Made of premium wear-resistant polyurethane, its abrasion resistance is 3-8 times that of manganese steel screens, with excellent fatigue resistance that prevents fracture under high-load impact, significantly reducing overall operating costs.

• Shock Absorption and Noise Reduction: The excellent damping characteristics of polyurethane effectively absorb material impact energy, reducing operating noise by 15-20 decibels compared to metal screens, significantly improving the workshop working environment while protecting the main structure of the screen.

4. Corrosion Resistance and Aging Resistance with Strong Adaptability

• Possesses excellent resistance to water, oil, acids, and alkalis, unaffected by moisture and corrosive media. It can operate stably over a wide temperature range of -30℃ to 80℃, making it widely suitable for various harsh working conditions.

Technical Parameters

• Material: High-performance wear-resistant polyurethane (hardness 85A-92A, customizable based on operating conditions)

• Installation Method: Side rail-mounted (compatible with mainstream vibrating screen and dewatering screen rails)

• Opening Design: Anti-blocking square holes, slots, inverted tapered holes, etc.

• Slot/Aperture: 0.2mm – 50mm (non-standard customization supported)

• Suitable Materials: Coal, iron ore, copper ore, potassium salt, quartz sand, and various moist, sticky fine materials

Application Areas

Widely used in mining beneficiation (e.g., wet screening of iron ore and copper ore), coal preparation plants (raw coal classification and desliming), sand and gravel aggregates (fine sand recovery and dewatering), as well as solid-liquid separation and material classification operations in chemical and building materials industries.
