Polyurethane Trommel Screens

GREX is an original manufacturer with independent workshop and proprietary polyurethane processing technology.

Our Polyurethane Flip Flow Screen Mats adopt self‑developed high‑elastic PU formula, flexible flip flow structure, effectively solve screen blinding for wet, sticky, fine‑grained materials.

Full customization, strict factory testing, widely used in coal, ore, sand, aggregate, mineral‑processing industries.

Features of Polyurethane Trommel Screens

Powerful Anti‑Blinding Self‑Cleaning Performance: Dynamic high‑frequency stretching‑relaxing movement removes sticky material automatically, effectively solving clogging & pegging problems for high‑moisture feedstock.

Premium Polyurethane Raw Material: High‑resilience PU, hardness 45‑95 Shore A, excellent tear strength, wear resistance and bending fatigue resistance, longer working life than rubber or steel screens.

High Screening Efficiency & Large Throughput: Open area 42%‑60%, flexible surface produces strong projectile acceleration, boosts processing capacity with low power consumption and low noise.

Fully Customizable Options: Aperture: square, slotted, round, elliptical holes; aperture & overall dimension can be tailor‑made; available in multiple colors.

Wide Installation Compatibility: Supports bolt‑on, screw fixing, wedge clamping, hook strip mounting, fits most OEM flip flow screen decks, direct aftermarket replacement available.

Broad Industry Adaptability: Works reliably for wet coal, sticky ore fines, damp sand, recycling waste and other hard‑screening materials.

Trommel Screens FAQ‘s

What materials are GREX flip flow screen mats best for?

They are ideal for wet, sticky, fine, high‑moisture materials, including wet coal, clay, mineral fines, moist sand, aggregates, construction demolition waste, compost, biomass and MSW, especially materials that easily block normal screens.

How does the self‑cleaning function work?

The screen mat is stretched and loosened cyclically by two offset screen frames. The fast elastic deformation shakes stuck particles out of holes, stopping blinding without extra cleaning equipment.

Can you produce custom size flip flow mats?

Yes. GREX supports fully customized length, width, thickness, aperture size, hole pattern and mounting holes, you can provide drawings, samples or machine parameters for quotationslotfilter…

What is the typical service life?

Under normal working conditions, well‑matched GREX PU flip flow screen mats can reach 4000+ working hours, service life depends on material abrasiveness, feed moisture, load and running parameters.

What’s your MOQ & lead time?

Small trial orders are acceptable; mass production lead‑time depends on whether standard or fully customized specifications. Please send your detailed requirements for an official offer.
