AN OVERVIEW OF THE MOST COMMON CONVEYOR BELT ISSUES

Even with regular inspections, conveyor belts can experience various issues that may lead to costly repairs and operational disruptions if left unaddressed. Understanding the most common problems and knowing how to resolve them is key to ensuring the longevity and efficiency of your system.

 

BELT MISALIGNMENT

Belt misalignment is a significant problem that can occur due to improper loading, skewed pulleys, or damaged rollers. It can be resolved by realigning the conveyor components, ensuring even material loading, and installing self-tracking systems to keep the belt properly positioned. To learn more on how to track a conveyor belt, read our dedicated article.

 

BELT SLIPPAGE

One significant challenge that can greatly affect conveyor efficiency is when the belt slips off the pulleys. This issue often arises from insufficient tension, worn drive pulleys, or contamination on the belt surface. To address this, operators should regularly check and adjust the belt tension, ensure that the pulleys are in good condition, and use high-friction lagging on the drive pulleys to enhance grip.

 

MATERIAL SPILLAGE

Material spillage happens when bulk materials fall off a conveyor belt or spill into its mechanism. This is usually caused by misaligned belts, excessive loading, or ineffective transfer points. To better manage transfer points and reduce conveyor spillage, consider installing skirting systems and impact cradles.

 

DEBRIS ACCUMULATION

Accumulation of debris is a common problem for conveyor systems. Dust, dirt, and residue from the materials being transported, as well as from the surrounding environment, can gather on the belt, rollers, and pulleys. To prevent excessive buildup and ensure smooth operation, it's essential to regularly clean the belt and its surrounding components. Installing belt scrapers and effective sealing systems can also help mitigate this issue.

 

ROLLER SEIZURE

A significant issue that can occur is roller seizure, where idlers and rollers cease to rotate due to excessive material buildup or structural damage, among other factors. When rollers seize, they create increased friction, which accelerates wear on the conveyor belt and raises the risk of fire hazards in certain environments. Regular inspections and timely replacement of damaged rollers are essential for ensuring smooth conveyor operation.

 

WEAR AND TEAR

Lastly, wear and tear are inevitable in any conveyor belt system, especially in applications involving high loads or abrasive materials. Cracks, cuts, and surface deterioration can compromise the integrity of the belt, leading to unexpected failures. To prolong the lifespan of the belt and reduce unplanned downtime, it's important to use high-quality materials, perform routine inspections, and schedule preventive maintenance.

By proactively addressing these common maintenance challenges, you can ensure that your conveyor systems operate safely, efficiently, and with minimal disruptions.


 

CONVEYOR BELT MAINTENANCE CHECKLIST

📋 DAILY MAINTENANCE TASKS

Here are the daily verifications you should perform:

  • Inspect the belt for visible damage such as cuts, crack or excessive wear.
  • Check for debris or material build-up on the belt, pulleys and rollers.
  • Listen for unusual noises that could indicate misaligned components or faulty rollers.
  • Verify the belt’s tracking to ensure it stays centered and does not drift.
  • Ensure proper belt tension to prevent slippage or excessive strain.
  • Look for signs of belt slippage or material spillage

 

📋 WEEKLY MAINTENANCE TASKS

We recommend you perform the following checks at least once a week:

  • Inspect idlers and rollers for wear, corrosion or seizure and replace faulty components.
  • Examine pulleys for misalignment, surface wear or lagging deterioration.
  • Check the drive system, including motors and gearboxes, for overheating, vibrations or leaks.
  • Inspect loading and transfer points for spillage, uneven material distribution or worn-out sealing systems.
  • Test belt cleaners and scrapers to ensure they effectively remove carryback and foreign objects.

 

📋 MONTHLY MAINTENANCE TASKS

Every month, schedule a maintenance checkup in order to:  

  • Conduct a detailed inspection of the belt and conveyor system emptied and shut down.
  • Check for structural misalignment in the conveyor frame that may affect belt tracking.
