What Causes Polyurethane Screen Panel Wear and How to Reduce It
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.
Primary Causes
| Cause Category | Specific Issue | Impact |
|---|---|---|
| Incorrect Hardness | Shore A >90 for fine ores | Blinding; stress cracking |
| Shore A 65–70 for coarse feed | Early tearing | |
| Improper Installation | Uneven tension | Edge wear; bolt damage |
| Feed-Related | Overfeeding | Thick bed prevents fines passage |
| Direct impact | Cracking | |
| Deck Cleanliness | Material buildup | Uneven support |
| Storage | UV/ozone degradation | Surface cracking |
Hardness Selection Guide
| Material Type | Recommended Hardness |
|---|---|
| Fine wet ores (sub-5mm) | Shore A 65–70 |
| Medium ores (5-25mm) | Shore A 75–80 |
| Coarse/heavy ores (>25mm) | Shore A 85–90 |
How to Reduce Wear
| Factor | Action |
|---|---|
| Hardness | Match to feed type |
| Installation | Tension 2–4%; check within 24 hours |
| Feed impact | Install wear strips at feed point |
| Cleaning | Daily debris removal; inspect support frame |
| Storage | Cool, dry, UV-protected; avoid stacking |
When to Replace
| Condition | Action |
|---|---|
| Aperture enlargement >20% | Replace immediately |
| Through-holes/cracks | Replace immediately |
| Uneven wear | Investigate; replace in sets |
