Why Is My Polyurethane Screen Panel Blinding? Causes & Fixes
Why Is My Polyurethane Screen Panel Blinding?
Screen blinding—the clogging of apertures—is a persistent headache in mineral processing. Even premium polyurethane panels can fall victim when material characteristics, design choices, or operating conditions are misaligned.
Primary Causes
| Cause Category | Specific Issue | Impact |
|---|---|---|
| Material Properties | Near-size particles (±10%) | Pegging |
| Moisture >8% | Agglomeration; coating | |
| Design Deficiencies | Open area <40% | Accelerated blinding |
| Wrong aperture geometry | Trapped irregular grains | |
| Hardness >90 Shore A (fine ores) | Loses self-cleaning | |
| Operational Issues | Frequency <1200 rpm | Insufficient G-force |
| Deck slope <15° or >25° | Piles up or races through | |
| Feed rate >5 t/(m²·h) | Overwhelms capacity |
Quick Fixes
| Problem | Action |
|---|---|
| Sticky feed | High-pressure water/air |
| Stuck particles | Soak; reduce hardness |
| Low vibration | Increase frequency/amplitude |
| Overfeeding | Cut feed rate 30–50% |
| Speed issues | Adjust deck angle to 18–22° |
Prevention
-
Slotted openings (3:1–5:1 aspect ratio)
-
Right hardness: fine wet ores = Shore A 65–70; coarse = 85–90
-
Tapered self-relieving apertures
-
Auxiliary cleaning systems
-
Routine inspections; proper tension and alignment
