Ball Tray Assemblies
Ball Tray Assemblies are the most common screen deblinding device and the most flexible. Used in a variety of deblinding applications, balls are sandwiched between the classifying mesh screen and a supporting screen. Suspended usually around two inches below the classifying mesh, the balls bounce between the two layers and are launched upwards by the vertical motion of the separator machine, impacting the classifying mesh with a sizeable force, and clearing the near-size particles from the screen openings.
Standard Construction
- Bottom Supporting Screen – 4 Market Grade x 0.047” T-304 Stainless Steel
- Screen Cleaning Devices – Standard 1-3/8” White EPDM, other compounds available upon request.
- Classification Screen – T-316 Stainless Steel mesh for separating the product.
- Sealing of Classification Screen – FDA / CFIA Approved Epoxy grade
Common Uses:
Deblinding ball Tray Assemblies are especially useful when using a coarser mesh due to the high impact energy and the bouncing/reverberating action. Typically, they are used when the mesh is greater than a 40 Market Grade mesh count. Ball Tray Assemblies are not recommended for fine screen meshes because mesh damage can occur. They are primarily used in dry applications.
Advantages:
- Very effective for material separation where the material tends to agglomerate or form balls.
- Works well for material separation using temperature-sensitive materials.
- Can be used when working with exceptionally hard irregularly shaped materials.
- Easy to take apart and clean.
- The classifying mesh screen can be switched out easily allowing for different classification screens to be used without having to replace the entire unit.
Frequently Asked Questions
Find answers to common questions about square/plain weave wire mesh.
Square weave wire mesh, also known as plain weave wire cloth, is woven by passing each warp wire alternately over and under each shute wire, creating uniform square openings. This classic weave pattern delivers excellent stability, consistent aperture size, and versatility for filtration, screening, and architectural applications.
Gerard Daniel offers several variations of plain weave mesh, including square plain mesh, square twilled mesh, market grade mesh, bolting cloth (tensile bolting cloth), and mill grade mesh. Each differs in wire diameter, mesh count, and open-area percentage to meet specific flow, strength, and precision needs.
Our square wire mesh is available in stainless steel (304, 304L, 316, 316L, 321, 347, 430), Monel®, Inconel®, Incoloy®, nickel, Aluminum, brass, bronze, and copper. We also carry low-carbon steel (C1008) and DFARS-compliant stainless alloys for government and aerospace applications.
In plain weave, each wire crosses over and under one wire at a time, providing stability and fine filtration control. In twilled weave, each wire passes over two and under two adjacent wires, producing a smoother surface and greater strength — ideal for applications under high mechanical stress.
Market grade square mesh is the most commonly used industrial wire cloth, offering a balanced combination of wire diameter and mesh count for general-purpose screening, sieving, and filtering in chemical, mining, food processing, and construction industries.
Tensile bolting cloth is a fine plain-weave mesh made from smaller wire diameters to achieve higher open area and precise particle control. It’s widely used in sifting, powder coating, and liquid filtration processes that require accurate separation.
Mill grade mesh bridges the gap between market grade and bolting cloth. It provides slightly higher open area for efficient separation, making it a preferred choice for dewatering, particle classification, and general screening operations.
We stock over 5,000 mesh types ranging from coarse openings (2 mesh) to fine meshes over 500 mesh. Most rolls are 48 inches wide and a hundred feet long, with custom widths, slit rolls, and laser-cut shapes available upon request.
Yes. If your specification isn’t in stock, we can weave custom mesh in any alloy, wire diameter, or mesh count to meet your filtration or architectural requirements. We also offer laser cutting, stamping, and slitting for made-to-order parts.
Every mesh roll is inspected for weave accuracy, wire diameter consistency, and open-area uniformity. As both a manufacturer and user of our own wire cloth in filtration and separation systems, we maintain strict quality control and repeatable performance standards across all mesh grades.
