Polyurethane screen parts(Screen capping)

It covers the top of the longitudinal beam rod in the vibrating screen to protect the screen mesh from being scratched by the longitudinal beam rod, reduce screen noise, and protect the screen plate.

Polyurethane Screen Capping is a protective polyurethane screen part installed on vibrating screens to cover and protect support bars, rails, or beams.
It helps reduce wear, absorb impact, and extend the service life of screening equipment under continuous vibration and material impact.

Compared with metal and rubber capping, polyurethane screen capping offers superior abrasion resistance, flexibility, and noise reduction.

Product Description

Polyurethane screen capping is designed to be mounted on the top of screen support bars or rails in vibrating screens.
Its primary function is to protect metal structures from direct contact with abrasive materials while providing cushioning and vibration damping.

Manufactured from high-performance cast polyurethane, screen capping combines elasticity and strength, making it suitable for heavy-duty screening applications in mining, quarrying, and bulk material handling industries.

By reducing wear on screen frames and rails, polyurethane screen capping helps lower maintenance costs and downtime.

Key Features

Outstanding Abrasion Resistance
Ideal for high-wear screening environments

Impact & Vibration Absorption
Protects screen structures and improves stability

Noise Reduction
Reduces noise caused by metal-to-material contact

Secure Fit on Screen Rails
Designed to stay firmly in place during vibration

Customizable Profiles
Various shapes and sizes available based on rail design

Typical Applications

Polyurethane screen capping is widely used in:

Vibrating screens

Mining screening equipment

Aggregate and quarry processing plants

Coal, sand, and stone screening systems

Bulk material handling equipment

Installation Position

Screen capping is typically installed:

On top of screen support bars

On rail beams under screen panels

At high-impact and high-abrasion contact areas

Polyurethane screen capping protects the screen rails and beams from wear while supporting screen panels during operation.
