Polyurethane Screens
Polyurethane screens (also called PU screen panels or urethane panels) are wear-resistant screening media used on vibrating screens in mining, quarry, aggregate, and recycling plants. They’re a practical choice when you need longer wear life, stable apertures, and modular panels that are easier to replace than full wire decks.
ANPENG manufactures polyurethane screening media and supplies custom panels matched to your screen model, deck layout, and operating conditions.
What Are Polyurethane Screens?
Polyurethane screens are molded or cast panels made from polyurethane material, designed as screening surfaces for vibrating screens. Unlike woven wire cloth that relies on metal wires, PU panels use a resilient polymer structure that handles abrasion well and maintains a stable aperture shape over time.
In many abrasive circuits, polyurethane screens are selected to reduce frequent change-outs and improve uptime—especially in high-wear zones where wire cloth may wear or break quickly.
Where Polyurethane Screens Work Best
Polyurethane panels are commonly used in:
Abrasive materials: hard rock, ore, sharp aggregate, mineral processing
High wear zones: feed end and impact areas
Sizing and classification: when stable apertures help maintain consistent product gradation
Plants prioritizing lower noise: compared with metal screening surfaces
Operations that prefer modular maintenance: replace worn panels instead of the whole deck
If your main issue is severe blinding from very wet/sticky fines, you may also consider self-cleaning wire screens or flip flow mats. PU panels excel in wear resistance, but material behavior still matters.
Key Benefits
Excellent abrasion resistance for harsh screening duty
Long wear life in many abrasive applications
Stable apertures for consistent sizing and repeatable separation
Reduced noise compared with many metal screen media
Modular panel design for faster change-outs and less downtime
Good corrosion resistance for many wet processing environments (depending on your plant conditions)

FAQs
When should I switch from woven wire to polyurethane screens?
When abrasion is high and wire cloth wears out too quickly, PU panels often provide longer service life and easier modular replacement.
Are polyurethane screens good for wet screening?
They can be used in wet circuits, but heavy clay/fines may still cause blinding depending on aperture and setup. Slot designs and process support can help.
Square vs slotted apertures—how do I choose?
Square openings are common for general sizing. Slotted openings may improve flow and reduce pegging for certain particle shapes or conditions.
How do I confirm the fixing system?
Confirm your deck’s mounting style (pin & sleeve, bolt-down, rail/clip, etc.). Photos of the current deck and panels are helpful.
What information do you need for a quote?
Material type, moisture, target cut size, tph, screen model, deck layout, and current issues (wear, pegging, blinding, carryover).
How can I extend wear life at the feed end?
Use the correct impact-zone panel design, keep supports in good condition, ensure proper fastening, and monitor wear patterns early.
