--- Applications of Conveyor Belts ---
• Mining and Heavy Industries:
In the mining and heavy industries, conveyor belts are the backbone of material transportation, especially in coal, metal ore, and mineral processing plants. A prime example is the collaboration between Kaifeng Iron Tower Rubber Group and a large-scale iron ore mine in Hebei Province. This mine required a solution for transporting highly abrasive iron ore over a 2.1-kilometer conveyor line with a 12% incline. Traditional belts failed within six months due to excessive wear and tear. Kaifeng Iron Tower supplied a custom-designed steel cord conveyor belt with a tensile strength of 2500 N/mm, a wear-resistant H-type cover layer (abrasion loss: 120 mm³), and a cold-resistant rubber layer suitable for seasonal temperature fluctuations. After implementation, the belt lasted over 36 months—more than five times the lifespan of previous models. The mine reported a 60% reduction in maintenance costs and a significant improvement in throughput. This success was attributed to the company’s provincial-level R&D center, which conducted extensive testing using advanced equipment such as the Mooney Viscometer and chemical analysis tools. Furthermore, the use of Kevlar-based and UPE anti-adhesion belts in other sections of the plant solved issues related to material buildup and environmental contamination. These innovations were developed in-house, reflecting Kaifeng Iron Tower’s commitment to technological leadership. As a wholly-owned subsidiary of Henan Energy Group—a Fortune 500 enterprise—the company leverages vast resources to deliver cutting-edge solutions. Its products are also used in cement plants, power stations, and port terminals across China and abroad, demonstrating their versatility and robustness. Whether facing extreme abrasion, high temperatures, or corrosive materials, Kaifeng Iron Tower’s conveyor belts consistently deliver performance, safety, and sustainability in the most demanding industrial environments.
• Food and Chemical Processing:
In food and chemical processing industries, conveyor belts must meet stringent hygiene, non-toxicity, and chemical resistance standards. Kaifeng Iron Tower Rubber Group has successfully addressed these challenges through its specialized product lines, including the self-cleaning and anti-adhesion conveyor belts. A notable case involved a fertilizer manufacturing plant in Shandong Province, which struggled with sticky urea granules adhering to the belt surface during return runs, causing cross-contamination and frequent cleaning interruptions. The plant adopted Kaifeng Iron Tower’s UPE anti-adhesion conveyor belt, featuring a layer of ultra-high molecular weight polyethylene film applied to the surface. Post-implementation, the adhesion rate dropped to less than 20% of that of conventional belts, significantly reducing downtime and improving sanitation. The belt’s water contact angle exceeded 70°, ensuring effective self-cleaning under wet conditions. Additionally, the company’s low rolling resistance energy-saving belts were introduced in the packaging section, resulting in a 15% reduction in motor power consumption. These belts were designed using LRR technology to minimize dynamic resistance between idlers and the belt, making them ideal for long-distance, high-volume operations. Kaifeng Iron Tower’s rigorous quality control—backed by ISO9001 and ISO14001 certifications—ensures that all materials are free from harmful substances and meet food-grade safety standards.

--- Choosing the Right Conveyor Belt ---
• Factors to Consider:
Selecting the optimal conveyor belt requires careful evaluation of multiple factors, including material type, operating environment, load capacity, inclination angle, and required lifespan. A real-world example from a coal-fired power station in Henan illustrates this process. The plant needed to upgrade its conveyor system for transporting raw coal over a 1.8-kilometer route with a 15° incline. Initial attempts with standard canvas belts failed due to rapid wear and slipping. After consulting with Kaifeng Iron Tower Rubber Group, the plant opted for a steel cord conveyor belt with a tensile strength of 2250 N/mm, a heat-resistant T2 covering layer (up to 125℃), and a low rolling resistance design. The decision was based on several key criteria: tensile strength (to prevent elongation), cover layer performance (for abrasion and heat resistance), and energy efficiency. Kaifeng Iron Tower’s technical team conducted a site assessment, analyzed material characteristics, and recommended a custom model matching GB/T9770-2013 standards. The result? A 50% increase in uptime and a 20% reduction in energy costs. Other critical factors include compliance with safety regulations (e.g., MT/T914-2019 for flame-retardant belts), ease of maintenance, and availability of after-sales service. Kaifeng Iron Tower’s global marketing network ensures prompt delivery and technical support, even in remote locations. Additionally, their use of advanced test equipment like the SYD-2651 viscometer ensures consistent rubber quality. Choosing a manufacturer with proven R&D capabilities, certifications (ISO9001, ISO14001), and real-world case studies—such as those from mines and power plants—can make all the difference. Avoiding generic suppliers without technical expertise or field validation is crucial. Ultimately, investing in a high-quality, well-matched conveyor belt from a reputable manufacturer like Kaifeng Iron Tower leads to long-term savings, enhanced safety, and operational excellence.
• Common Mistakes to Avoid:
One of the most common mistakes in conveyor belt selection is choosing a belt based solely on cost, ignoring long-term performance and total cost of ownership. A cautionary tale comes from a small cement plant in Anhui Province, which replaced its durable steel cord belts with a cheaper, non-flame-retardant PVC belt to cut expenses. Within four months, the belt suffered severe degradation due to high temperatures and abrasive materials, leading to a complete shutdown. The repair and replacement costs exceeded the initial savings by 300%. Another frequent error is mixing different belt types or grades in a single system—something Kaifeng Iron Tower explicitly warns against in its usage guidelines. In one instance, a mining company connected a Grade 6 PVG belt with a Grade 8 belt, causing uneven stress distribution and premature failure. Similarly, failing to maintain proper tension or allowing the belt to operate while submerged in water can drastically reduce lifespan. Kaifeng Iron Tower emphasizes the importance of correct installation, including using the recommended minimum drum diameter (e.g., 630 mm for 1400S PVG belts) and avoiding reverse usage. Another mistake is overlooking specialized requirements such as anti-adhesion for wet materials or self-cleaning for viscous substances. For example, a fertilizer plant ignored the need for a UPE anti-adhesion belt and faced constant clogging issues. By contrast, when they switched to Kaifeng Iron Tower’s solution, productivity soared. To avoid these pitfalls, companies should consult certified manufacturers with proven track records, access technical support, and follow standardized procedures. Kaifeng Iron Tower’s role as vice-chairman of the China Rubber Hose and Belt Association and its receipt of “Henan Province High-tech Enterprise” status underscore its authority. Always prioritize quality, compliance, and expert guidance over short-term savings.
