Our 18-inch sandwich screens are built for compact screening systems where screen blinding and frequent changeouts interrupt productivity. These dual-layer screens use integrated self-cleaning elements like Nylon Sliders or Rubber Balls to keep mesh clear and extend screen life—ideal for labs, pilot plants, and specialty food or pharmaceutical production.

Sandwich Screen vs. Standard Single-Layer Screen

• Prevents Clogging: Keeps mesh clear in fine powder or damp material applications
• Longer Service Life: Support mesh and epoxy bonding reduce wear under frequent use
• Ideal for Labs & Testing: Compact size and quick-change design suit fast-paced pilot environments

• Trusted Design: Seamlessly integrates with most industry-standard 18-inch vibratory screeners.
• Flexible Configurations: Customizable options for mesh grades and de-blinding mechanisms to suit specific operational needs.
• Versatile Use: Suitable for applications across food, pharmaceutical, and industrial sectors.

• Lead Times: Orders ship within 5–7 business days.
• Shipping Options: Parcel or freight shipping available based on screen size.
• Expedited Shipping: Available upon request—contact us to prioritize your order.

This 18-inch sandwich screen is commonly used in:

• Pharmaceutical R&D Labs: Keeps active ingredients and fine powders flowing smoothly
• Food & Nutraceutical Testing: Screens spice blends, flours, and powders with less blinding
• Specialty Chemicals: Reduces static and clogging issues in lab-scale batch runs
• Small-Scale Processing Lines: Ideal for short production cycles or portable screener setups

• Automatic De-Blinding: Utilizes gentle vibration with rotating Nylon Sliders or Rubber Balls to prevent mesh blockage, eliminating the need for manual cleaning.
• Rapid Screen Changes: Easy access to both mesh layers allows for quick screen changes, ideal for frequent production runs or material variations.
• Cost Savings: Durable, reusable design extends screen life and reduces replacement costs compared to traditional screens.
• Customizable Options: Choose between Nylon Sliders, Rubber Balls, or a combination of both for optimal performance tailored to your application.
• Wide Compatibility: Fits most major 18-inch vibratory screeners without requiring a center spacer, simplifying installation.

• Diameter: 18 inches.
• De-Blinding Media: Nylon Sliders, Rubber Balls, or combination options available.
• Materials: FDA-approved, food-safe construction for safe handling of materials.
• Bonding: Epoxy-bonded mesh ensures durability and reusability.

Q: What is a sandwich screen and how does it work?
A: A sandwich screen uses two bonded mesh layers—a fine working mesh supported by a coarser mesh—with built-in de-blinding elements to reduce clogging and wear.

Q: What types of de-blinding media can I choose from?
A: You can select Nylon Sliders, Rubber Balls, or a combination of both depending on your material type and process flow.

Q: Will this screen fit an 18-inch Sweco®-style screener?
A: Yes. It’s designed to integrate with most 18-inch round vibratory screeners without the need for a center spacer.

Q: What bonding method is used?

A: Epoxy bonding is used to provide food-safe, durable adhesion between the mesh layers.
