High-Temperature Industrial Pain Points: Frequent Failures of Heat-Resistant Rubber Conveyor Belts Sound the Safety Alarm

In high-temperature industrial environments such as steel mills, cement plants, foundries, and power stations, heat-resistant rubber conveyor belts play a critical role in material handling. However, recent reports highlight a growing concern: frequent failures of these belts under extreme heat conditions, leading to operational disruptions, increased maintenance costs, and severe safety risks. These incidents serve as a stark reminder for industries to prioritize advanced, reliable solutions to prevent accidents and ensure uninterrupted production.

Heat-resistant conveyor belts are designed to withstand temperatures ranging from 100°C to 400°C, transporting hot materials like clinker, sintered ore, coke, and slag. Yet, common pain points include delamination of rubber layers, cracking due to thermal degradation, reduced tensile strength, and premature wear, often exacerbated by poor material adhesion or inadequate compounding. Such failures can result in belt breakage, material spillage, fires, or even explosions in dusty, high-heat settings, posing threats to worker safety and equipment integrity. Industry data indicates that belt-related downtime in high-temperature operations can account for up to 30% of total maintenance expenses, underscoring the urgent need for enhanced durability and monitoring.

Zaozhuang Jinflex Rubber & Plastic Technology Co., Ltd (Jinflex), a leading manufacturer of specialized rubber conveyor belts, addresses these challenges with its advanced heat-resistant series. Utilizing premium heat-resistant rubber compounds, high-strength EP/NN fabric or steel cord carcasses, and special anti-aging additives, Jinflex belts maintain structural integrity at peak temperatures up to 400°C. They feature low elongation, superior abrasion resistance, and strong layer bonding through optimized vulcanization processes, significantly reducing failure rates. Compliant with international standards like DIN22131, RMA, and JIS K6369, these belts have proven effective in real-world applications, extending service life by 50-100% compared to standard options.

Experts recommend regular inspections, proper installation, and selecting belts with customized cover thicknesses (e.g., 5-10mm top cover) to mitigate risks. Jinflex offers tailored consultations to help industries upgrade their systems, emphasizing preventive measures like temperature monitoring and material compatibility assessments.

As global industrial demands intensify under sustainability goals, addressing these high-temperature pain points is essential. Jinflex remains committed to innovation, providing cost-effective, safe solutions that safeguard operations and personnel.
