Common Failures in Low-Quality Conveyor Belts and How to Avoid Them

In industrial environments, conveyor belts play a critical role in ensuring efficient operations, transporting materials across facilities with ease and consistency. However, the quality of a conveyor belt directly impacts its durability, safety, and performance. Using low-quality conveyor belts may seem like a cost-effective solution initially, but they can lead to significant operational disruptions, safety hazards, and increased maintenance costs. Here, we explore the common failures associated with low-quality conveyor belts and discuss strategies to avoid these costly issues.

 

 

1. Increased Wear and Tear

Low-quality conveyor belts are typically made from subpar materials and/or processes that wear out much faster than high-quality conveyor belts. The rubber or synthetic compounds used in these belts often lack durability, making them susceptible to accelerated wear under regular industrial loads. This wear can manifest as cuts, delaminations, abrasions, and cracks on the belt’s surface, making it challenging to maintain a consistent flow of materials.

 

Impact: Frequent wear and tear can result in costly downtime as belts need to be replaced or repaired more often. This downtime disrupts production, decreasing operational efficiency and leading to potential financial losses.

 

Prevention: Investing in high-quality conveyor belts with abrasion-resistant materials can significantly reduce wear and tear. Durable options, like those made from reinforced rubber compounds or advanced polymers, are better equipped to withstand heavy-duty loads, thus extending the lifespan of your conveyor belt and reducing the frequency of replacements.

 

 

2. Misalignment Issues

Low-quality belts often lack dimensional stability and uniform thickness, which can lead to misalignment. Even slight variances in belt dimensions can cause the belt to track off course, creating operational issues such as jamming or material spillage. Misalignment can also increase friction on one side of the belt, leading to premature edge wear and reducing overall belt life.

 

Impact: Misaligned belts can cause uneven loading, jamming, or worse, equipment damage, resulting in expensive repairs. Additionally, misalignment can cause safety hazards, such as materials spilling off the conveyor and creating risks for workers.

 

Prevention: Choose conveyor belts from reputable suppliers like Davis Industrial who adhere to precise manufacturing standards. Quality belts are engineered with dimensional accuracy and uniform thickness to reduce the risk of misalignment. Implementing tracking devices on your conveyors also helps keep belts properly aligned, reducing the risk of wear and operational issues.

 

 

3. Susceptibility to Tearing and Breaking

Low-quality conveyor belts are often composed of weaker materials, making them prone to tears or breaks under heavy load. When a conveyor belt fails mid-operation, the downtime for repairs or replacements can be substantial, and any materials currently on the belt may be damaged or lost in the process.

 

Impact: Belt tears and breaks disrupt production, often requiring the entire line to be shut down. The cost of replacement parts and labor for repairs can add up quickly, making low-quality belts an expensive option over time. For businesses handling abrasive or sharp materials, this issue can be even more pronounced.

 

Prevention: Opt for belts with high tensile strength and resistance to tearing. Reinforced belts with layered fabrics or metallic inserts can help withstand the demands of tough materials. Regular inspections and preventive maintenance further help identify any early signs of tearing, allowing for timely interventions before major issues arise.

 

 

4. Heat and Chemical Resistance Deficiencies

Some industries, such as mining, food processing, and manufacturing, require conveyor belts to withstand exposure to extreme temperatures or chemicals. Low-quality belts may not offer adequate heat or chemical resistance, leading to premature degradation of the belt material. Exposure to heat can cause belts to soften, crack, or even melt, while chemicals may break down the belt material or cause it to swell.

 

Impact: In applications involving heat or chemicals, using belts without the necessary resistance can lead to frequent failures, contamination risks, and operational disruptions. A conveyor belt that degrades due to chemical exposure or heat can become a severe safety hazard, especially in high-risk industrial environments.

 

Prevention: Invest in conveyor belts specifically designed for extreme conditions. Heat-resistant or chemical-resistant belts are available and are made from materials like EPDM, silicone, or specialized rubbers that are formulated to handle harsh environments. Feel free to contact Davis Industrial with any questions to ensure the belt material matches the specific demands of your application.

 

 

5. Vulcanization and Joint Failures

In low-quality conveyor belts, the  carcass and coverings are often poorly made, resulting in weak points along the belt. Inadequate vulcanization can lead to splice failure, which may cause the belt to snap or split under tension. Splice failures are not only costly but also extremely dangerous, especially if a belt fails while carrying heavy or hazardous materials.

 

Impact: Splice failures can be catastrophic, bringing operations to a sudden halt and creating potential hazards for nearby workers. Not only does this lead to extensive belt damage that often requires complete replacement rather than simple repairs, it can damage the system itself. 

 

Prevention: Choose conveyor belts with high-quality carcasses and coverings, and pair them with the appropriate splice method, whether mechanical or vulcanized. Additionally, selecting splice materials specifically suited to your application and belt type is crucial. Regular inspection of splices and joints can also help identify early signs of weakness, preventing costly breakdowns.

 

 

6. Higher Energy Consumption

Low-quality belts with poor construction can cause increased friction within the conveyor system, leading to higher energy consumption. Irregular surfaces or inadequate material quality increases drag, forcing the conveyor’s motor to work harder and consume more energy to maintain the same level of productivity.

 

Impact: Increased energy consumption results in higher operational costs, which over time can far outweigh the initial savings from choosing a cheaper belt. The additional strain on the motor can also lead to more frequent maintenance or premature motor failure.

 

Prevention: Invest in high-quality belts designed with smooth surfaces and low-friction materials. Selecting belts specifically engineered to reduce drag can lead to more energy-efficient operations, ultimately saving money on energy bills and reducing the environmental impact.

 

 

7. Frequent Maintenance and Higher Long-Term Costs

While low-quality conveyor belts may have a lower initial cost, the frequent need for maintenance quickly adds up. Downtime, labor, and replacement parts contribute to a high total cost of ownership. Frequent repairs also divert labor resources and reduce productivity, putting a strain on both financial and human resources.

 

Impact: Constant maintenance interrupts workflows and reduces production output, which can impact profitability and operational efficiency. In competitive industries, these disruptions can also result in delayed delivery times and loss of customer trust.

 

Prevention: Investing in high-quality conveyor belts with proven durability and longevity is often more cost-effective in the long run. High-quality belts not only require less frequent maintenance but are also less likely to experience unexpected breakdowns, allowing for more consistent and reliable operations.

 

 

 

Opting for low-quality conveyor belts might appear to save money upfront, but the hidden costs and risks can be substantial. Inferior belts not only deteriorate more quickly, leading to increased maintenance and repair expenses, but they also consume more energy and can compromise workplace safety. These hidden costs and disruptions ultimately outweigh any initial savings. By investing in premium, high-quality conveyor belts, you’ll minimize downtime, reduce maintenance frequency, and foster a safer, more efficient work environment.
