How to Choose a Veneer Dryer Wire Mesh Belt

Choose a veneer dryer wire mesh belt by starting with the dryer and the job the belt performs. If your existing belt has been working well, matching its original specification is the simplest starting point. For a new dryer or a change in veneer quality, compare sheet support, the contact surface and airflow before choosing the final mesh and material.

1. Confirm where the belt works in your dryer

Veneer dryers can use different transport arrangements, including belts or rollers. A dryer description such as “jet dryer” does not, by itself, identify the belt you need. Check the actual conveying arrangement and identify the belt position.

On equipment fitted with both a lower carry belt and an upper cover belt, say which one you are ordering. For a multi-deck dryer, label the deck as well. Do not assume that every belt in the machine has the same width, length or construction.

The spiral mesh construction discussed here uses coiled wires connected by cross rods. PFM lists flat and round spiral-wire options on its veneer dryer wire mesh belt product page. “Flat spiral wire” describes the wire cross-section; it should not be used as a substitute name for a honeycomb flat wire belt.

2. Start with your purchasing situation

Replacing a belt that already works well

Use the existing drawing, original specification or a belt sample as your reference. Keep a record of the mesh, edges and end joint before removing the belt. A photo of the full belt width plus close-ups of the mesh and edge is a useful starting point when the original paperwork is missing.

Choosing a belt for a new dryer

Start with the veneer thickness, sheet size and surface requirements, together with the proposed belt position. Ask the equipment designer and belt supplier to review the mesh alongside the support arrangement, rollers, drive and tensioning travel. Select the belt as part of that conveying arrangement.

Changing a belt because the current result is unsatisfactory

Describe the problem before asking for a different mesh: surface marks, poor sheet support, blocked openings or edge wear. Include photos showing where the problem occurs. This gives the review a specific objective instead of treating a denser mesh or a different steel grade as an automatic upgrade.

3. Compare the contact surface and the mesh together

Flat spiral wire presents a broader contact face; round spiral wire has a circular cross-section. That difference is useful when discussing veneer contact, but it does not establish a complete performance ranking.

Ask for the spiral-wire dimensions, spiral pitch and cross-rod pitch when comparing proposals. Pitch is a centre-to-centre dimension, not the clear gap between adjacent wires. These details make two quotations easier to compare than a general description such as “fine mesh”.

4. Match material and construction to the actual conditions

PFM lists stainless steel 304, 316/316L, carbon steel and galvanized steel options. Treat these as materials to assess for the application, rather than interchangeable choices. Provide the normal and maximum zone temperatures, any known belt temperature, and the cleaning method. Mention persistent moisture, corrosion or resin deposits on the old belt.

For a replacement that has given satisfactory service, first identify its original material. If you want to change it, explain why. A general alloy temperature rating should not be used as the allowable operating temperature of a complete belt.

Confirm the two side edges separately from the end joint that closes the belt into a loop. Before approving an order, also confirm overall width and loop length, with the measurement basis stated. For several decks or belt positions, list each belt separately rather than multiplying one specification by the deck count.
