Measuring mesh size

When selecting wire screen media for different aggregate sizes, it’s essential to determine the appropriate mesh size and wire diameter for your specific application needs. 

Here’s how you can measure and choose the right wire screen media.

Mesh Size
The mesh size indicates the number of openings per linear inch in the wire screen media. A higher mesh count means finer openings, while a lower mesh count means coarser openings.

How to Measure Mesh Size
Lay the wire screen media flat on a surface. Count the number of openings (meshes) within a linear inch. Use a ruler or measuring tape along the length of the wire screen and count the openings. Mesh size is expressed as the number of openings per linear inch (e.g., 10 mesh, 20 mesh, 50 mesh).

How to Measure Wire Diameter
Wire diameter refers to the thickness of the wire used in the screen’s construction. Thicker wires are generally for heavier-duty applications, while thinner wires are for finer screening.

To measure wire diameter, use a micrometer or caliper to measure the diameter of a single wire strand. Measure at several points along the wire to account for any variations.

Alternatively, consult the manufacturer’s specifications, which typically include wire diameter information.

Aggregate Size Consideration
After determining the mesh size and wire diameter, select the appropriate combination based on the aggregate sizes being processed.

• Fine Aggregates: For materials like sand or fine gravel, use finer mesh sizes (higher mesh count) for accurate screening.
• Larger Aggregates: For materials like crushed stone or gravel, use coarser mesh sizes (lower mesh count) to allow larger particles to pass through while effectively separating smaller particles.

Consultation with Experts
For specialized applications or challenging materials, consulting experts or manufacturers specializing in wire screen media can provide valuable guidance and recommendations.

By accurately measuring mesh size and wire diameter and considering the aggregate size, you can optimize screening efficiency and performance.
