Belt conveyors are the workhorses of many industries, tirelessly moving materials from one point to another. From airports to manufacturing plants, these systems play a crucial role in keeping operations running smoothly. However, like any piece of machinery, belt conveyors can face various issues that can disrupt productivity and cause headaches for operators. In this blog post, we’ll discuss some common conveyor belt problems and solutions to keep them running efficiently.
Common Belt Conveyors Problems And Their Solutions
-
Belt Mistracking: Keeping Things on the Straight and Narrow
One of the most frequent belt conveyor problems is mistracking, where the belt veers off to one side instead of staying centered. This problem can lead to uneven wear, material spillage, and even complete system failure if left unchecked.
Solution: Mistracking often occurs due to several factors, including uneven loading, misaligned rollers, or damage to the belt itself. Look for signs of wear on the edges of the belt and check the alignment of rollers and pulleys. Adjusting the tension and alignment of the belt can often resolve minor tracking issues. For more severe cases, you may need to replace damaged components or seek professional help to realign the entire system.
-
Belt Slippage: Maintaining the Right Grip
Another common problem is belt slippage, where the belt fails to maintain proper contact with the drive pulley. This can result in reduced efficiency, increased wear, and even motor damage in extreme cases.
Solution: Slippage often occurs due to insufficient tension, worn pulleys, or excessive loads. To combat this issue, ensure that the belt tension is correctly adjusted according to the manufacturer’s specifications. Regular cleaning of the pulleys and belt surfaces can also help maintain proper friction. Installing additional lagging on the drive pulley can sometimes improve grip and reduce slippage.
-
Material Spillage: Keeping Things Where They Belong
Spillage of materials from the conveyor belt is not just wasteful; it can also create safety hazards and increase maintenance requirements. This is one of the top belt conveyor problems. It is often seen at transfer points or when the belt is overloaded.
Solution: To minimize spillage, start by ensuring that the loading zone is properly designed and maintained. Installing skirt boards along the sides of the belt can help contain materials, especially in the loading area. Regular inspection and maintenance of seals and wipers can also go a long way in preventing spillage. For particularly challenging materials, consider using specialized conveyor belt designs or additional containment systems.
-
Carryback: Dealing with Clingy Materials
Carryback refers to materials that stick to the belt and are carried back on the return side of the conveyor. This can lead to material waste, increased cleaning requirements, and potential damage to rollers and other components.
Solution: To combat carryback, installing effective belt cleaning systems is key. Primary and secondary belt cleaners can remove the majority of material adhering to the belt. For particularly sticky materials, specialized tertiary cleaning systems or belt washing stations may be necessary. Regular inspection and maintenance of these cleaning systems are crucial to ensure their effectiveness over time.
-
Seized Rollers: Keeping Things Rolling
Rollers that have seized or become damaged can cause significant problems, including increased power consumption, belt damage, and potential fire hazards. This issue is often caused by lack of lubrication, contamination, or overloading.
Solution: Preventive maintenance is the best defense against seized rollers. Implement a regular inspection schedule to identify rollers that are showing signs of wear or damage. Lubricate bearings according to the manufacturer’s recommendations, and consider using sealed or self-lubricating rollers in dusty or contaminated environments. When replacing rollers, ensure they are properly aligned to prevent additional stress on the system.
-
Belt Wear and Damage: Extending Belt Life
The conveyor belt itself is often the most expensive component of the system, and premature wear or damage can lead to significant downtime and replacement costs. Belt wear can be caused by a variety of factors, including abrasive materials, misalignment, and improper tension.
Solution: To extend belt life, start with proper selection – choose a belt material and design that’s appropriate for your specific application. Make sure that the belt is correctly tensioned and tracked to prevent unnecessary wear. Consider installing impact beds or cushioned idlers in loading zones to reduce stress on the belt.

Noise and Vibration: Creating a Better Work Environment
Excessive noise and vibration from a belt conveyor system can create an unpleasant work environment and may indicate underlying mechanical issues.
Solution: To address noise and vibration problems, start by identifying the source. Common culprits include misaligned components, worn bearings, or loose hardware. Regular maintenance and tightening of components can often resolve minor noise issues. For more significant problems, consider installing vibration dampeners or upgrading to quieter belt designs.
Tips for Conveyor Maintenance
Good maintenance practices are key to solving many conveyor belt problems and solutions. Here are some practical tips to help you maintain your conveyor belt effectively:
-
Inspect Regularly
Create a schedule for routine checks. Check for evidence of wear, damage, or misalignment. Early detection of problems can help to avoid larger difficulties later on.
- Keep It Clean
Dirt and debris can cause many belt conveyor problems. Clean the belts, rollers, and pulleys regularly. This simple step can extend the life of your system significantly.
- Listen and Watch
Pay attention to unusual noises or vibrations. These could be early indicators of possible problems. If something doesn’t seem right, investigate promptly.
- Lubricate Moving Parts
Proper lubrication keeps things running smoothly. Follow the manufacturer’s guidelines for what to lubricate and how often.
- Check Belt Tension
The right tension is crucial for proper operation. Being too snug or too loose can cause issues. Adjust as needed, following your system’s specifications.
- Train Your Team
Make sure everyone who works with the conveyor knows basic maintenance and safety procedures. This can help prevent accidents and catch issues early.
- Keep Spare Parts on Hand
Having common replacement parts ready can reduce downtime when something needs fixing. This is especially important for critical components.
- Document Everything
Keep detailed records of all maintenance activities and repairs. This history can help identify recurring issues and plan for future maintenance.
- Address Problems Promptly
Don’t wait to fix small issues. They can quickly turn into bigger, more expensive problems if left unattended.
- Schedule Professional Check-ups
While regular in-house maintenance is important, having a professional inspection periodically can catch things you might miss.
