What Causes Polyurethane Screen Panel Wear and How Do I Reduce It?

Polyurethane screen panels are among the most wear-resistant screening media available, but they are not indestructible. Premature wear and failure usually trace back to a combination of material selection, installation practices, and operational conditions.

Understanding the root causes is the first step toward extending service life.

Primary Causes

1. Incorrect Hardness

Hardness	Best For	Risk
Shore A 65–70	Fine wet ores (<5mm)	Too soft for coarse feed
Shore A 75–80	Medium ores (5–25mm)	Generally balanced
Shore A 85–90	Coarse ores (>25mm)	Too hard for fine wet screening

2. Improper Installation — Uneven tension creates edge wear and bolt damage

3. Feed-Related Factors — Overfeeding, direct impact without wear strips, incompatible aperture design

4. Deck Cleanliness — Material buildup creates uneven support; damaged frame forces panel to absorb structural loads

5. Storage — UV/ozone degradation; improper stacking

How to Reduce Wear

Factor	Action
Hardness	Match to feed: 65–70 (fine), 75–80 (medium), 85–90 (coarse)
Installation	Follow torque specs; tension 2–4%
Feed impact	Install wear strips at feed point
Cleaning	Daily debris removal; inspect support frame
Storage	Cool, dry, UV-protected

When to Replace

Condition	Action
Aperture enlargement >20%	Replace immediately
Through-holes/cracks	Replace immediately
Uneven wear	Investigate; replace in sets
