Screen Mesh

Woven wire, polyurethane, and slotted screen media for coal sizing and dewatering screens.

Overview

About this part

Screen mesh is the working surface of vibrating screens and is the most frequently replaced component in a screening installation. Mesh types include woven wire (highest open area), polyurethane modular panels (longest life, lowest noise), and slotted dewatering panels. Mesh selection balances cut accuracy, throughput capacity, panel life, noise, and cost per ton screened.

Materials

Material Options

Woven wire (carbon steel)
Standard mesh for dry coal sizing. Highest open area, lowest cost, shortest life.
Woven wire (stainless)
Used where corrosion or product contamination by rust is a concern.
Polyurethane modular
Cast polyurethane panels in a standard module size. Long life, low noise, blinding-resistant.
Rubber modular
Cast rubber panels, used at high-impact feed points where polyurethane would tear.
Wedge wire (slotted)
Profile wire bars forming non-blinding slots for dewatering and fine sizing.

Replacement

Replacement Notes

Wire mesh is replaced when wear opens the apertures beyond tolerance. Polyurethane modules are replaced when individual modules wear through or when the deck open area falls below acceptable. Tracking replacement intervals against tonnage screened is essential for benchmarking suppliers.

Frequently Asked

FAQ

Wire or polyurethane screen panels — which lasts longer?

Polyurethane panels typically last 2–5x longer than wire panels in the same duty, with lower noise and better blinding resistance. Wire has higher open area (more throughput per square meter), so the total economics depend on tonnage, downtime cost, and how often panels can be changed.

What is screen blinding?

Blinding is the progressive plugging of screen apertures by near-mesh particles, which gets worse as fines accumulate and bridge across the openings. Wet, sticky coal blinds faster than dry coal. Self-cleaning slot designs, anti-blinding balls, and ultrasonic deblinding reduce the effect.

Why do wedge wire screens work better for dewatering than woven wire?

Wedge wire screens have a slot that widens away from the working surface, so once a particle passes the working surface it falls through rather than wedging in the aperture. Woven wire dewatering screens blind more readily because the aperture width is constant through its depth.

How do I specify a screen panel order?

Provide the screen make and model (which defines the deck attachment system and panel size), the aperture you need, the material grade, and the quantity per deck. For modular panels, the deck position layout (feed, middle, discharge end) affects panel grade selection.
