【Weekly Topic】The main factors affecting the lifespan of conveyor belts and how to extend their lifespan? (2011.06.27-07.04)

Factors affecting the service life of the conveyor belt: 1. The strength of the conveyor belt does not meet the required standards (this is related to specific usage requirements, especially the material from which the conveyor belt is made). 2. Errors in the original design of the equipment, especially those related to the loading points, cause materials to impact the conveyor belt rapidly, or improper loading leads to the belt shifting out of place. 3. From the manufacturer’s perspective, they can only influence the last factor in order to ensure that the product meets the required standards. Protection measures for conveyor belts: 1. Improving product quality (for example, by using rubber belts with low wear) is intended to extend the service life of conveyor belts; however, any one of the three factors mentioned above can render the investment in improving product quality unnecessary. 2. The design for lateral deflection reduces the elongation of the conveyor belt, and it is specifically used for long-distance transportation. 3. Shear-resistant transmission belt: The internal structure of the shear-resistant transmission belt is similar to that of a standard composite epoxy resin transmission belt, with the addition of transverse steel cables on the top rubber layer; these cables provide protection for the fragile belt body through their restraining effect. It is the elasticity of these lateral steel cables that enables the shear-resistant conveyor belt to possess the same level of flexibility as traditional fiber conveyor belts ； In other words, the anti-shear conveyor belt resembles a traditional epoxy resin conveyor belt, but it has a stronger steel core than traditional belts. 4. System improvement: In some older devices, especially those with steel-core belts, the service life is extended by increasing the tensile strength of the belts, but this approach actually does not yield much effect. Some belt manufacturers invest in various detection systems. Coils are placed at fixed angles within the conveyor belt to serve as antennas, and corresponding sensors are installed on the equipment to detect whether all coils are present; if a coil is missing, it indicates that the conveyor belt in that area is damaged. The electronic control system will automatically stop the operation of the entire equipment, and the faster the stop, the less damage to the conveyor belt.

Errors in the original design of the equipment, especially those related to the loading points, cause materials to impact the conveyor belt violently; or improper loading leads to the belt shifting. The strength of the conveyor belt is not sufficient to meet the required standards (this is related to specific usage requirements, particularly the material used for the belt). From the manufacturer’s perspective, they can only influence the last factor in order to ensure that the product meets the required standards.

From the manufacturer’s perspective, they can only influence the last factor in order to ensure that the product meets the required standards. Mechanical transmission is widely used in mechanical engineering. Common types of mechanical transmission systems include gear transmission, worm and worm gear transmission, belt transmission, chain transmission, and gear trains. In mechanical transmission, belt drives have relatively lower costs compared to other types of transmission methods. Currently, the desired service strength is achieved in the high tensile resistance of internal components such as steel cores, epoxy resin, or aromatic polyamide fibers. However, it also has its own weaknesses; namely, it cannot effectively resist cutting, shearing, and impact damage from materials. A minor accident can lead to a **reduced lifespan** of the conveyor belt. This article analyzes the service life of conveyor belts based on the following three factors, any of which can affect its service life: 1. The strength of the conveyor belt is not sufficient to meet the requirements (this is related to specific usage conditions, especially the material used for the conveyor belt). 2. Errors in the original design of the equipment, especially those related to the loading points, cause materials to impact the conveyor belt rapidly, or improper loading leads to the belt shifting out of place. 3.

Regarding this, many people have reported that the lifespan of conveyor belts is not very long； To this end, we conducted specific interviews with several manufacturers, and through these we learned why drive belts do not have a long lifespan. The specific reasons are as follows ； 1. Poor maintenance (especially in dusty conditions). 2. Errors in the original design of the equipment, especially those related to the loading points, cause materials to strike the conveyor belt rapidly, or improper loading leads to the belt shifting out of place. 3. The strength of the conveyor belt is not sufficient to meet the requirements (this is related to specific usage conditions, particularly the material used for the belt). From the manufacturer’s perspective, they can only influence the last factor in order to ensure that the product meets the required standards. To address the above points, we need to take appropriate measures to extend the lifespan of the conveyor belt. Magnetic separator ； Improving product quality (such as by using rubber belts with low wear) is intended to extend the service life of the conveyor belts, but any one of the three factors mentioned above can render the investment in improving product quality unworthy. With the installation and use of the first batch of land-based steel-core drive belts, such problems have become increasingly prominent. The high cost does not yield high performance in terms of cut resistance and impact resistance; therefore, it is necessary to develop a system to prevent accidental incidents, and installing a magnetic separator at the loading point seems to be a solution. However, it turned out that this only solved the problem partially: for example, during routine maintenance, metal tools left on or accidentally falling onto the conveyor belt can pierce it like razors. Improve the system ； The enormous economic losses make it extremely urgent to find a way to minimize the damage. Although in some older devices, especially those with steel-core belts, the service life is extended by increasing the tensile strength of the belt, this approach actually does not yield much effect. More effective technical solutions to this problem have now been found. Some belt manufacturers are investing in various detection systems. Although these detection systems are based on different physical principles, the basic principle behind their installation is the same: coils are placed at fixed angles within the conveyor belt to serve as antennas, and accompanying sensors are installed on the equipment to detect whether the coils pass through. If a coil is missing, it indicates that the conveyor belt in that area is damaged; the electronic control system will then automatically stop the operation of the entire device, and the faster the stop occurs, the less damage to the conveyor belt. However, this method is not perfect either; if the coil next to the sensor happens to be damaged, problems arise. To avoid this, we place Z-shaped conductors along the conveyor belt within the main body of the belt, forming a circular coil; any damage to a point on this coil will cause the entire circuit to be interrupted. Therefore, by placing a sensor in the most appropriate location on the equipment, it’s easy to detect any damaged areas of the drive belt. It seems to be the ideal solution to the problem, but based on practical experience in the field, it also has its shortcomings: coil damage can occur due to mechanical pressure, and the sensors may issue alarms thinking that there is a problem with the conveyor belt, thereby stopping operations. Since the extensive damage to antennas inevitably results in unavoidable economic losses, another simple approach was considered as a substitute for using antennas, and that is to simply refrain from using protection systems. Ultimately, people will question whether it is worth investing extra money in belts to install antennas, electronic devices, and sensors, thereby creating an advanced technical system – only for the entire system to become useless once some of the antennas are damaged Lateral flexion drive belts have also been successfully applied in short-distance load-bearing equipment. Large pieces of material fall straight from a height and strike the conveyor belt with force; such impacts become particularly dangerous when the equipment is operating at low speeds. The most representative example is a laterally deflecting conveyor belt only 10 meters long, installed in a limestone quarry in northern Italy. Due to an initial design flaw, the stones passed through the crushing machine fell directly from a height of one meter onto the conveyor belt; carrying and transporting such heavy and large stones caused the conveyor belt to fail in a very short time. Installing special impact idlers under the conveyor belt can only maintain its functionality for about a month on average; it seems that this method cannot solve the problem – a stone that is heavier than the designed weight is sufficient to damage the newly installed conveyor belt. Since the only other possible solution was to rebuild the plant, it was decided to install lateral flex drive belts. This drive belt has a service life of over one year, and its durability is ten times that of ordinary fiber drive belts. Anti-shear transmission belt ； This type of conveyor belt can match lateral flexion conveyor belts in terms of resistance to damage, while still retaining the advantages of fiber conveyor belts, such as: · Light weight · Easy installation and connection · High flexibility · Low cost · Abundant availability. The internal structure of this shear-resistant conveyor belt is similar to that of standard composite epoxy resin conveyor belts, with the addition of transverse steel cables on the top rubber layer; these cables provide protection for the fragile belt body through their restraining effect. It is the elasticity of these lateral steel cables that enables the shear-resistant conveyor belt to possess the same level of flexibility as traditional fiber conveyor belts ； In other words, the anti-shear conveyor belt resembles a traditional epoxy resin conveyor belt, but it has a stronger steel core than traditional belts. The differences between anti-shear transmission belts and standard fiber transmission belts in terms of shear resistance and tensile strength. The peak corresponds to the point where the steel cable breaks. For special load-bearing requirements, the energy required to break the drive belt can be increased by increasing the number of steel cables and reducing the peak distance. It is mainly used for scraping metals and glass, as well as dealing with concrete debris. Shear-resistant belts can be used wherever sharp objects might damage the conveyor belt. This type of system can also be used in automated machinery; since small wheel diameters and lightweight drive belts are required, side-flexible drive belts cannot be used. Conclusion: Lateral flexion belts and shear-resistant belts are a true alternative for detecting belt damage using electronic systems. This undoubtedly **improves** the weak resistance of the steel core. Shear-resistant fiber conveyor belts are lighter and cheaper than steel-core lateral flexure conveyor belts, while offering the same resistance to shear and impact.
