A Complete Guide for Conveyor Belt Repair and its Maintenance

Conveyor belts are an essential part of many industries, including mining, manufacturing, and logistics. They are used to transport materials and products throughout a facility, and a breakdown or malfunction can result in costly downtime. In this guide, we will discuss the importance of conveyor belt maintenance and provide tips for repairing and maintaining your conveyor belt to ensure it operates efficiently and safely.

Regular inspections of the conveyor belt

Regular inspections are essential for identifying potential issues with your conveyor belt before they become major problems. Inspect the belt for wear and tear, cracks, frayed edges, and any other signs of damage. Check the belt tension and alignment, as well as the condition of the rollers and idlers. Inspect the motor, gearbox, and bearings for any signs of wear or damage.

Proper cleaning

Keeping your conveyor belt clean is critical to its performance and longevity. Dirt and debris can cause the belt to slip or wear prematurely, while spills and contaminants can damage the belt’s surface. Clean the belt regularly using a soft brush or cloth, and avoid using harsh chemicals that could damage the belt material. Also, ensure that the belt’s underside is free of debris to prevent build-up and ensure smooth operation. Another tool that helps in the cleaning of conveyor belts is Belt-O-Cleaner or Adhesive Primer (spray form). These products not only help in cleaning but also work tremendously as bonding enhancers.

Belt alignment and tension

Proper belt alignment and tension are crucial to ensuring that your conveyor belt operates smoothly and without issues. Make sure that the belt is correctly aligned and that the tension is appropriate for the application. Misaligned belts can cause excessive wear and damage to the belt’s edges, while too much tension can lead to premature wear and tear.


The proper lubrication of the conveyor belt is crucial to its performance and longevity. Proper lubrication can prevent wear and tear and reduce friction, extending the life of the belt. Lubricate the bearings, rollers, and other moving parts regularly, and ensure that you use the correct type of lubricant for the application.

Proper storage

When not in use, it’s crucial to store the conveyor belt correctly to prevent damage or deformation. Store the belt in a dry, clean area away from direct sunlight, and avoid stacking heavy objects on top of it. Make sure the belt is rolled or folded correctly, as improper storage can cause permanent damage and impact its performance.

Repairing damaged belts

If you notice any damage to your conveyor belt, such as cracks, tears, or frayed edges, it’s essential to repair it as soon as possible to prevent further damage. Depending on the extent of the damage, you may be able to repair the belt yourself, or you may need to call in a professional. Minor repairs, such as patching small tears or filling cracks with a repair compound, can often be done in-house. However, for more extensive damage, it’s best to call in a professional to avoid causing further damage. There are a lot of companies that provide the ideal products for conveyor belt repair. Oliver Rubber Industries LLP from India is among the top names that arrive to the mind whenever we talk about repairing and jointing conveyor belts.

Types of Conveyor Belt Repair

Hot Vulcanizing

Hot vulcanizing is a conveyor belt repair method that involves using heat and pressure to bond two conveyor belts together. It is a permanent solution that creates a strong and durable bond between two conveyor belts. Hot Vulcanizing is suitable for repairing tears, punctures, and other damage to the conveyor belt surface.

Cold Vulcanizing

Cold vulcanizing is another conveyor belt repair method that does not involve heat. Instead, it uses a chemical bonding agent to join conveyor belts together. Cold Vulcanizing Solution with hardener is an ideal adhesive for splicing and jointing conveyor belts. However, there are a few qualities that a cold vulcanizing adhesive must have in it, which are: Non-flammable, Unlimited Shelf Life, and High Bonding Strength.

Pulley Lagging

Pulley lagging is a process of covering the pulley surface with rubber to improve traction between the conveyor belt and the pulley. It helps prevent slippage and belt damage. Pulley lagging is suitable for both new and used conveyor belts. It also helps extend the life of the conveyor belt and reduce maintenance costs.


A few other ways for conveyor belt repair are using the instant repair kits for longitudinal cuts and holes, employing a rubber sheet in the manufacturing plant, using skirt rubber to avoid material spillage, etc.

In conclusion, regular maintenance and proper care are essential to keep your conveyor belt operating smoothly and without issues. By following these tips, you can extend the life of your conveyor belt and prevent costly downtime. Remember to regularly inspect your belt, keep it clean, ensure proper alignment and tension, lubricate moving parts, store it correctly, and repair or replace any damaged or worn-out parts promptly.
