Why Is My Screen Panel Pegging and How to Prevent It

Why Is My Screen Panel Pegging and How Do I Prevent It?

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. The result is lost screening area, reduced throughput, and unscheduled downtime.

What Causes Pegging?

Cause	Impact
Near-Size Particles (±10% of aperture)	Wedge into openings; block finer material
Incompatible Aperture Shape	Elongated particles lodge in slotted openings
Insufficient Vibration	Low G-force fails to eject particles
Feed Segregation	Localized overloading creates hot spots
Moisture (3–8%)	Capillary forces help particles wedge

Prevention Strategies

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	Ensure 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

Quick Diagnostic

Indicator	Likely Cause	Action
Wedged particles	Near-size >30%; low vibration	Check PSD; increase G-force
Pegging in certain 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
