High-Angle Corrugated Sidewall Conveyor Belts

The high-angle corrugated sidewall conveyor belt is widely utilized due to its ability to transport materials at steep angles with a compact footprint. Despite its efficiency and adaptability, it encounters several common faults that can impact performance and longevity. This article discusses these issues and proposes improvement measures to enhance operational reliability.

1. Roller Adhesion Causing Belt Wear

(1) Cause of Failure

• Material composition: Variability in material composition, moisture content, and viscosity.

• Adhesion: Accumulation of materials on rollers, pulleys, and drums.

• Wear Mechanism: Adhered materials generate uneven surfaces, causing wear during belt operation.

(2) Improvement Measures

• Install scrapers on rollers, pulleys, and drums to maintain smooth surfaces.

• Improve feeding speed control to manage material flow and prevent spillage.

• Regular cleaning schedules to remove adhered materials.

2. Belt Deviation Leading to Material Leakage and Wear

(1) Causes of Failure

• Misalignment of roller axis and belt centerline.

• Uneven roller leveling or material accumulation on rollers creating conical surfaces.

• Excessive tension or improper loading leading to belt drift.

(2) Improvement Measures

• Adjust tail roller screw rods and pressure to realign the belt.

• Regularly clean rollers to prevent material-induced misalignment.

• Monitor and adjust tension to balance load distribution.

• Train maintenance personnel for quick identification and correction of deviations.

3. Severe Sidewall Wear

(1) Cause of Failure

• Contact between the belt’s sidewall and the pulley, often due to:

• No gap between the inner ring and sidewall top.

• Fixed small wheels in pulleys not rotating, increasing friction.

• Inclined contact surfaces leading to uneven wear.

(2) Improvement Measures

• Separate guide wheel pressure systems for sidewalls and empty edges to reduce friction.

• Replace inclined pressure wheels with parallel, independently rolling wheels.

• Widen reversing pressure wheels to reduce localized stress on the sidewall.

4. Other Common Conditions

(1) Material Accumulation

• Accumulation at the head and tail can hinder roller function, causing belt deviation or sidewall damage.

• Solution: Regular cleaning after loading or shifts.

(2) Feeding Imbalances

• Overloading or underloading disrupts balance, leading to excessive stress on diaphragms and material spillage.

• Solution: Ensure balanced and controlled material feed.

(3) Sidewall and Diaphragm Damage

• Loose or damaged sidewalls and diaphragms can worsen belt integrity.

• Solution: Prompt repairs using vulcanization or repair rubber.

(4) Belt Tension Issues

• Excessive tension can overstrain the belt, especially at turning points, leading to skirt overload.

• Solution: Adjust belt tension to optimal levels.

Maintenance and Care

1. Daily Maintenance

• Inspect for cuts, cracks, and degumming.

• Ensure rollers rotate freely and replace damaged ones.

• Clean rubber scrapers and adjust cleaning devices as necessary.

• Focus on cleaning tail sections prone to material accumulation.

2. Regular Maintenance

• Lubricate rotating parts, bearings, and gears.

• Inspect and replace worn gears and cooling lubricants in the reducer.

• Tighten loose bolts and replace worn components.

• Perform a comprehensive inspection of structural components, including rollers and frames.

Conclusion

High-angle corrugated sidewall conveyor belts are indispensable in industrial material transport. By addressing issues like roller adhesion, belt deviation, and sidewall wear through systematic improvements and rigorous maintenance, these belts can achieve greater efficiency and extended service life. Collaboration with experienced manufacturers ensures optimal performance and reliability in demanding production environments.
