If your conveyor belt isn’t working properly, it will have untold ramifications throughout your entire system. Entire operations can be thrown off schedule, resulting in loss of both money and productivity.
To prevent this from happening, you need to keep a close eye on the precise workings of your conveyor belts. By carefully watching and checking up on your belts, you can catch many problems before they develop into larger issues that take time and money to fix.
No matter how careful you are, mistakes still happen, and parts and equipment eventually break down. When this inevitably happens, it’s important to know how to fix complications as they arise.
It’s crucial for you to understand how to complete conveyor belt maintenance as well as what some of the more common conveyor belt problems are and how to fix them. This information will help you keep your conveyor belts running smoothly and stop them from breaking down due to preventable issues.
While it is impossible to compile a list of every bad situation you will ever encounter with your conveyor belt, this is a list of some of the concerns you are most likely to face, as well as their probable consequences.
In addtion to learning more about the most common conveyor belt issues, learn:
This issue occurs when there is a conveyor belt tracking problem. Tracking is the process of managing and aligning the belt onto the correct path, and it’s critical to ensuring the smooth functioning and output of your system. Mistracking, then, is when something goes wrong along this track. In most cases, it means that the belt has slipped to one side or another, and the entire system has shifted out of alignment.
Mistracking leads to numerous negative consequences. It has the potential to throw the entire system off its specified course. But the consequences can also be less extreme than this. Mistracking might simply lead to uneven belt wear, which is the cause of a whole host of other problems in its own right.
If the belt slips entirely off the track, the whole system could begin malfunctioning and shut down. It’s best to keep an eye out for small signs of mistracking, even if they don’t seem to be causing much damage. By catching this problem early on, you can prevent it from worsening and creating a larger issue.
When your belt starts tracking from side to side and experiencing frayed edges, you need to do a little conveyor belt alignment troubleshooting. Conveyor tracking problems can originate from various parts of your system. As soon as your belt starts mistracking, take a look at these potential problems:
Conveyor belts rely on a precise balance of tension to work correctly. If there is too much tension or too little, things begin to go awry, and the belt can slip. Specifically, if the head pulley breaks down or even becomes overly worn, there will no longer be enough tension to keep the belt from slipping around.
This loss of tension can result in unnecessary stretching and strain on the belt, as well as loud, grating and squealing noises and the aforementioned slipping. It will require time-consuming maintenance to fix such a problem as this. To avoid this situation, check all parts and pieces of the conveyor belt regularly to ensure that they aren’t experiencing any undue wear and tear.
Since tension and balance play massive roles in belt operation and traction, there are a few common causes of belt slippage. Once you’re aware of the potential causes, you can keep an eye on problem areas to prevent slippage in the future. Common causes include:
When your conveyor belt constantly slips, it disrupts your daily operation and productivity. If you stay aware of the potential causes, you can prevent them before they happen. It’s helpful to regularly inspect your machine, especially the pulleys as they often contribute to belt slippage.
In most cases, conveyor belts are constructed from metallic materials such as steel. This construction is good because it means the parts are usually highly durable and long-lasting. However, it also means that when the rollers on the conveyor belt seize up, they have an unfortunate tendency to develop sharp edges.
These sharp edges, in turn, can have major repercussions throughout the conveyor system. They can cause the belt to mistrack unequally down the center line of the conveyor belt. This circumstance is an issue for several reasons. Firstly, it can pose a significant safety hazard to any workers in proximity to the conveyor belt. Secondly, it has the potential to damage goods and materials being transported along the conveyor belt, sometimes beyond repair.
If the problem is severe enough that the entire system malfunctions and shuts down, you will most likely be looking at a long shut-down period while the system is repaired. Check the rollers frequently to prevent this scenario.
The primary purpose of any conveyor belt system is to transport items efficiently from one location to another, often through a complex conveyor system. It only makes sense, then, that when this efficient travel is disrupted, the entire system stops working.
It’s all too easy for a package to get caught. When this happens, the next item behind the first one gets caught, and the pileup simply builds from there. It can lead to the entire system becoming clogged and jammed.
While random occurrences are hard to predict and often impossible to prevent, you can do a great deal to stop preventable blockages. Check your conveyor belts carefully for any sharp edges, surfaces, corners or other spaces that might snag items as they go past. Remember that even if something looks like it’s not a big deal now, it’s always better to deal with it while it’s still small. Otherwise, it might soon become a much larger complication.
While blockages are a result of packages getting caught on sharp edges and blocking the other products, material carryback involves a buildup of material on the belt itself. If you’re working with materials such as clays or mineral ores, they can leave small amounts of residue behind. While it may not seem like much, this material will increase and lead to accumulation underneath your belt, causing problems with your rollers and pulleys.
This carryback can also cause safety issues down the road because excessive material buildup can be a fire hazard, and certain materials can be dangerous if frequently inhaled. There’s also a profit loss associated with carryback. If you’re working with high-profile materials and losing a little bit of them every time they’re on the belt, you could lose a significant profit.
To reduce material carryback, you should install a cleaning system that will scrape your belt to ensure no material gets left behind.
It’s fairly common for there to be some issues with material spillage at some point along a conveyor system. This term refers to any material that accidentally slides or spills off the belt, and it’s most common along transfer and load points. This occurrence isn’t necessarily due to any mechanical failures or problems with the belt, but it can still be an issue, as this spilled material can lead to blockages or buildups that will have a domino effect and cause other problems later on.
If you find that material spillage is a common factor on your conveyor belt, try installing impact beds, skirt clamps or a belt plough. These solutions will help reduce wasted material as well as time spent cleaning up, and they’ll decrease the possibility of breakdowns caused by blockages on the belt.
Depending on the product you’re moving, you might experience perforations or tears in your belt. Moving products such as sharp rocks or coal increases the chances of this occurrence. Even excessive friction from moving heavy packages can result in thin spots that eventually lead to tears. Seam rips also happen over time with stress and tension on the belt. Tears and rips can be hard to prevent with the nature of your operation, so this problem requires a good repair process.
A torn belt or ripped seam can cause problems with the function of your belt and hurt productivity. It’s important to either contact a professional or have a trained member of your team perform these repairs to reduce downtime.
There is a broad range of solutions for conveyor belt problems that you can consider to make repairs. These repairs depend on the belt’s material, your industry and how much space your operation has.
The three methods of conveyor belt seam repair are:
The best way to keep your conveyor system running smoothly is always to prevent problems before they happen. This plan requires constant vigilance, and it calls for you to regularly check your system for anything incurring excessive wear, or any elements slightly out of the ordinary.

Here are a few of the most important things you can do to keep your system running smoothly.
As part of the regular checkups you perform on your conveyor belt, you should complete a routine cleanliness check. Carefully look over your entire system from top to bottom, side to side and every way you can think of. Look for buildups of dirt, debris or residue of any kind. Wherever you find these types of buildup, remove them as thoroughly as possible.
Debris is a common cause of mistracking. It can cause the belt to become aligned incorrectly, and it can also be responsible for blockages in your system.
This process goes hand in hand with checking for buildups. However, if you clean regularly, you reduce the possibility of allowing buildups to happen in the first place. Make a regular habit of cleaning your conveyor system. You’ll be more likely to catch issues early on and prevent any problems that would arise as a result of dirt or excess material buildup.
It’s hard for your conveyor to run properly if the entire system is tilted at an unusual angle or thrown out of alignment, which can happen just from the regular motion of the machine as well any number of other factors. It may have even occurred when the system was being readjusted for transporting a different product or material.
It’s essential to check regularly to make sure the conveyor frame is squared up neatly and everything is lined up correctly. You can easily confirm by using a standard level and checking to make sure that both sides are even.
Pulleys are easy to check at the same time that you’re already investigating whether the frame is square. Verify that each pulley in the system is evenly lined up with the conveyor frame. If these pulleys are off, this could lead to bigger problems with the belt slipping and parts wearing down more quickly.
This feature isn’t necessarily something you need to check every time you perform maintenance since looking at it once will get the job done. However, it’s still crucial to perform this analysis. While ideally, every belt is cut and formed perfectly, it’s not impossible that you may have gotten a defective belt that simply isn’t cut straight. If you didn’t know about this defect, it could be wreaking all kinds of havoc in your conveyor system through mistracking.
To check whether or not your belt is straight, try this. Remove the belt from the conveyor frame and lay it out flat on the floor. If the belt arcs or curves in any way, it isn’t straight, and it will need to be replaced.
The conveyor belt’s return idlers can become dirty, frozen or incorrectly aligned over time due to improper installation or natural wear, tear and motion. These parts should be cleaned regularly, and their alignment should be checked.
If your idlers freeze or stop working in any way, it could have various ramifications for your system. It could lead to your belt wearing out faster than usual and needing to be replaced, among other possibilities. To avoid this situation, simply check the idlers regularly for any problems, cleaning them as they become dirty and replacing them as they begin to wear out.
This advice should go without saying, but it’s so important that it’s worth drawing special attention to. If any single part of your conveyor system begins to wear down, it needs to be replaced. If it is allowed to continue breaking down without replacement, it will put added strain on the other parts as they work to carry the extra load that the damaged part is unable to. This situation results in the rest of your system breaking down more quickly or malfunctioning and needing to be shut down altogether.
There are many reasons a part could break down. It could be that there was excessive buildup destroying the material or that the part was never installed correctly and it was experiencing excessive strain. Or it could simply be that the part has grown old and is naturally breaking down with time. Whatever the case, it’s important to replace it now before it causes damage to the rest of the system.
Belt maintenance is crucial for an efficient product line. If you actively check your conveyor belt’s activity and prepare to handle problems, your operation will run smoothly. Keep these maintenance tips in mind when caring for your conveyor belt:
This is valuable for belts that you actively use throughout the day. Have a plan for emergency repairs by stocking equipment such as cold-curing supplies or metal fasteners so you can repair rips quickly. It’s also wise to have a plan of action for production. Will you stop that line completely, or can you move it elsewhere while you make repairs?
You should also keep a stock of spare parts. Things such as sprockets, motors and belts will need to be replaced over time. Keep them available if any part failure should arise.
How long do your conveyor belts typically last with your type of production? If you have a belt that doesn’t meet that standard lifespan, it could indicate a manufacturing error or even poor maintenance and care. If you know how long a belt lasts, you can make sure you’re actively caring for it to support that lifespan.
The best way to avoid a severe malfunctioning error is to follow the steps listed above. Following these tips can improve your conveyor belt’s lifespan and help you avoid bigger problems, ultimately making your line more productive.
Make a note of any repairs you perform, and write down the state of your parts regularly in a conveyor belt plan. If a more significant problem comes up, you could access these notes to see repairs you’ve made in the past, and if the state of your belt showed failure over time.
Start a Conveyor Belt Maintenance Schedule With a Technician
As much as preventive maintenance is a good practice, working with a professional technician for belt maintenance services guarantees that the bigger repairs will be done correctly. Set up regular maintenance with a professional so they can fill in the gaps of your actions.
While not as inherently dangerous as many other pieces of heavy machinery and equipment, conveyors are still capable of serious damage if the correct safety measures aren’t taken. If you or any of your team members are about to start maintenance work, take note of these key safety precautions before you begin.
This point cannot be stressed enough. Do not perform maintenance on the conveyor system while it is in use. Doing so would be a good way to get a finger crushed or broken if your fingers happen to get caught in the machinery. Even more dangerous is the electrical current powering the conveyor belt. To avoid problems with dangers such as these, take extra precautions. Be safe and make sure everything is shut off before you begin maintenance.
The amount of electricity needed to power a conveyor system is nothing to take lightly. That kind of power can cause serious damage, especially if you’re inexperienced and aren’t especially sure what you’re doing. If you begin to suspect that the problem with your conveyor belt is much more involved than anything we’ve covered here, take a step back. It may be time to call in a professional maintenance team. While this may seem like an extra hassle, it’s always better to be safe than to end up seriously damaging your system or endangering yourself or an employee.
