Solving Blinding & Pegging Challenges
Blinding and pegging occur when material becomes lodged in screen openings, reducing throughput and forcing frequent stoppages for cleaning or screen replacement. These issues are common when screening fine, wet, sticky, or near-size materials.
Traditional single-layer screens often struggle to stay clean under these conditions. Once openings begin to clog, screening efficiency drops, and manual intervention is required. Self-cleaning screens, including anti-clogging screen designs like sandwich screens, are used to help keep openings clear and reduce downtime caused by material buildup.
What Are Self-Cleaning Sandwich Screens?
Self-Cleaning Sandwich Screens are self-cleaning screen filters constructed with two layers of stainless-steel screen mesh and self-cleaning media contained between them.
During operation, vibration activates the internal media, helping to dislodge material that begins to lodge in the mesh openings. This continuous action helps maintain an open area and supports cleaner screens throughout the screening process. Reducing material buildup inside the mesh provides more consistent performance than traditional single-layer screens.
Key Benefits of Self-Cleaning Screens
- Reduced Blinding & Pegging: Anti-clogging screen design helps prevent material buildup in screen openings.
- Cleaner Screens During Operation: Internal self-cleaning action supports clean screens without frequent stoppages.
- Consistent Throughput: Maintains steady material flow and separation efficiency.
- Less Manual Cleaning: Reduces downtime caused by stopping equipment to clean screens.
- Durable Stainless Steel Screen Mesh: Built for reliable performance in industrial screening environments.
Compared to traditional single-layer screens, Self-Cleaning Sandwich Screens help reduce the need for frequent stoppages caused by blinding and pegging. With the self-cleaning function built directly into the screen, installation and removal are simplified while eliminating the need for additional components. This integrated design helps maintain active screen openings, supporting longer production runs, more consistent throughput, and reduced labor associated with manual cleaning and frequent changeouts.
In certain applications, the sizing mesh may experience wear before the rest of the screen assembly. When this occurs, re-screening can be a practical, lower-cost alternative to full replacement. You can reach out to us to discuss re-screening options for your application.
Ideal Applications & Materials
Self-Cleaning Sandwich Screens are well-suited for screening materials that commonly cause clogging, including:
- Wet or high-moisture materials
- Sticky or cohesive materials
- Fine or near-size particles
These self-cleaning screens are used in industrial screening applications where maintaining clean screens and minimizing downtime are critical to productivity.
Material & Design Options
Self-Cleaning Sandwich Screens in this collection are constructed using stainless steel screen mesh with self-cleaning media positioned between mesh layers.
This layered design supports anti-clogging performance by allowing internal movement that helps free lodged particles during operation. Screen specifications vary by size to ensure proper fit and performance in compatible vibratory screening equipment.
Installation & Performance Optimization
Proper installation is essential for maintaining the performance of self-cleaning screen filters.
Recommended practices include:
- Proper screen tensioning
- Correct vibration and machine setup
- Routine inspection to help maintain clean screens and identify wear
Following these steps helps maximize screen life and supports consistent screening performance.
