Distinguishing Between Mesh Blinding and Particle Pegging: Causes and Solutions

Do you frequently encounter issues with screen blinding and particle wedging during material screening? In fact, there is a significant difference between the two. What are the causes of these problems, and how can they be resolved? Here’s the thing: if your screen’s losing capacity and fine particles are just sitting on top like wet sand, you’re dealing with mesh blinding. This happens when sticky materials—think clay, wet sand, or recycled asphalt—cling to the mesh openings instead of passing through. It’s not a blockage; it’s adhesion. The fix? Start with water sprays，just a light, targeted mist can wash away the gunk without drowning the feed. Or switch to a polyurethane screen with a self-cleaning surface.
