Huatao Group-Vibrating Screen Technology Solution and Service for Quarry & Mining Industry Since 2008.
Screen pegging—where particles wedge firmly into screen openings—is one of the most persistent problems in wet and dry screening operations. Unlike surface blinding, pegging occurs when near-size particles lodge directly into apertures.
| Cause | Impact |
|---|---|
| Near-Size Particles (±10%) | Wedge into openings |
| Wrong Aperture Shape | Elongated particles lodge |
| Low Vibration | Fails to eject particles |
| Feed Segregation | Creates hot spots |
| Moisture (3–8%) | Adhesion forces |
| Strategy | Action |
|---|---|
| Adjust Aperture Size | Move cut point away from near-size peak |
| Choose Right Shape | Dry: square/round; Wet: slotted with wash water |
| Increase G-Force | Dislodge particles before they wedge |
| Even Feed Distribution | Uniform bed depth across full width |
| Optimize Moisture | Add wash water; stay below 3–8% for dry |
| Inspect and Maintain | Worn apertures trap new near-size populations |
| Indicator | Likely Cause | Action |
|---|---|---|
| Wedged particles | Near-size >30%; low vibration | Check PSD; increase G-force |
| Pegging in areas | Uneven feed | Adjust feed spreader |
| Dry, elongate material | Wrong aperture shape | Switch to square/round |
| Moist material (3–8%) | Adhesion | Add wash water or reduce moisture |
| Worsens over time | Worn apertures | Measure; replace panels |
