Stop Blinding. Start Screening

Screen blinding is one of the most common challenges in screening operations. Whether you’re processing powders, food ingredients, chemicals, minerals, or aggregates, blinded screens can reduce throughput, impact product quality, and increase downtime.

When screen openings become blocked by particles, material can no longer pass efficiently through the mesh. The result is reduced productivity, more frequent screen changes, and higher operating costs.

At Compass Wire Cloth, we offer a variety of de-blinding solutions designed to keep your screens performing at their best. Because every material behaves differently, there is no single solution that works for every application. That’s why we work closely with customers to identify the most effective approach based on the material, process, and operating conditions.

Ball Tray Assembly

Ideal for Near-Size Particles

Near-size particles are often one of the most difficult causes of screen blinding. These particles are just large enough to become lodged in the screen opening, reducing open area and screening efficiency.

A Ball Tray Assembly uses specially designed mesh cleaning balls that continuously bounce beneath the screen during operation. This action helps dislodge trapped particles and keeps the mesh open for maximum throughput.

Benefits:

• Controls blinding caused by near-size particles
• Improves screening efficiency
• Increases throughput
• Extends screen performance between maintenance intervals

Slider Tray Assembly

Best for Wet or Suspended Materials

When screen blinding is caused by wet, sticky, or suspended particles, a Slider Tray Assembly can be an effective solution.

Sliders move beneath the screen during operation, creating continuous motion that helps dislodge material before it can clog the mesh openings. Available in both single and cluster configurations, slider assemblies help maintain screen efficiency while reducing manual cleaning and downtime.

Benefits:

• Helps prevent blinding from wet or sticky materials
• Improves screen productivity
• Reduces cleaning interruptions
• Available in multiple configurations

Perforated Plate

Heavy-Duty Support and Scalping Applications

A Perforated Plate is commonly used in conjunction with slider tray and ball tray assemblies. The plate provides support while allowing cleaning components to operate effectively beneath the screen.

In some heavy scalping applications, a perforated plate can also be used in place of a traditional screen.

Benefits:

• Supports slider and ball tray assemblies
• Provides durability in demanding applications
• Suitable for heavy scalping operations
• Helps maintain efficient material flow

Every Material Is Different

While these are proven de-blinding solutions, material behavior can often be unpredictable. Particle shape, moisture content, density, and flow characteristics all influence how material interacts with a screen.

That’s why Compass Wire Cloth doesn’t believe in one-size-fits-all solutions. Our team works with customers to evaluate their specific application and recommend the most effective de-blinding system—or develop a custom solution when necessary.

Keep Your Screens Working Harder

Screen blinding doesn’t have to be accepted as a normal part of the process. With the right de-blinding solution, operations can improve throughput, reduce downtime, and maximize screen life.
