Guide to Measuring and Identifying a Balanced Woven Conveyor Belt

Balanced woven conveyor belts are a popular choice in various industries due to their durability, versatility, and ability to withstand a wide range of operating conditions. To ensure accurate replacement, repair, or ordering, it is crucial to correctly measure and identify the specifications of an existing belt. This guide provides a detailed step-by-step process for measuring and identifying these belts.

Materials Needed

• ● Measuring tape or ruler
• ● Calipers

Key Parameters to Measure

1. Belt Material

• ● Identification: Inspect the belt for visible markings or consult with the supplier for the material type (e.g., stainless steel 304, 316, or carbon steel).
• ● Tip: For high-temperature or corrosive environments, confirm the belt material aligns with the application's requirements.

2. Wire Diameter

• ● Spiral Wire:
• ○ Use calipers to measure the diameter of the spiral wire (Spiral wire can be round wire or flat wire).
• ○ Take multiple readings at different locations to account for wear or deformation.

• ● Cross Rod:
• ○ Measure the diameter of the cross rod similarly.

3. Spiral Wire Pitch

• ● You can measure the length of the spiral loops in integers around 20 cm and count the number of these spiral loops. 
• ● Spiral Wire Pitch = (measured length - Spiral Wire Diameter) / number of spiral loops
• ● Example:

4. Cross Rod Pitch

• ● Calculate the Cross Rod Pitch using a similar method to measuring Spiral Wire Pitch
• ● Example:

5. Belt Width and Length

• ● Width:
  • ○ Measure the belt from edge to edge using a measuring tape.
• ● Length:
  • ○ Lay the belt flat and fully extend it. Use a measuring tape to determine the total length. For installed belts, measure a single section and multiply by the number of sections.

6. Edge Type

• ● Examine the edges closely to determine the construction type:
• ○ Welded Edge

• ○ Laddered Edge

• ○ Hook Edge

• ○ Chain Edge

7. Mesh Type

• ● Standard Balanced Spiral Woven Belt

• Double Balanced Spiral Woven Belt

• ● Standard balanced Spiral Woven Belt with straight cross wire

• Double Balanced Spiral Woven Belt with straight cross wire

8. Operating Temperature

• ● Ensure the material’s operating range aligns with the application’s temperature requirements.

9. Drive Type

• ● Identify whether the belt is friction-driven or positive-driven by examining sprocket or pulley engagement marks.

Tips for Accurate Measurements

1. Clean the belt to remove debris before measuring.
2. Take multiple readings to minimize errors.
3. Document measurements and note any wear or damage.
4. When in doubt, provide photos to your supplier with a reference scale (e.g., a ruler).
