Reliable Conveyor Belt Solution for High-Temperature Material Handling

Product Overview

Heat-resistant conveyor belts are specially engineered industrial conveyor belts designed to transport hot materials safely and efficiently in high-temperature working environments. In industries such as cement manufacturing, steel production, power generation, mining, and metallurgy, materials are often conveyed immediately after heating processes, such as clinker discharge, sintering, slag handling, or hot ash transportation. These materials can reach temperatures far beyond the tolerance of standard rubber conveyor belts.

Heat-resistant conveyor belts are manufactured using advanced heat-resistant rubber compounds and reinforced belt structures that maintain mechanical strength, flexibility, and surface integrity under continuous thermal exposure. By resisting thermal degradation, cracking, and hardening, these belts ensure stable conveying performance, extended service life, and reduced downtime.

What Is a Heat Resistant Conveyor Belt

A heat-resistant conveyor belt is a type of rubber conveyor belt specifically designed to withstand prolonged exposure to elevated material temperatures without losing performance or structural integrity. Unlike ordinary conveyor belts, which may harden, crack, or deform under heat, heat-resistant belts use specially formulated rubber covers that resist thermal aging and maintain elasticity.

These belts are essential in conveying systems where the material temperature typically ranges from 100°C to over 400°C, depending on belt grade and application conditions.

Why Heat Resistance Matters in Conveyor Systems

High temperatures accelerate rubber aging and can cause rapid belt failure if unsuitable materials are used. Common problems caused by heat exposure include surface cracking, cover hardening, delamination, and loss of tensile strength. Once a belt deteriorates, it may lead to unexpected shutdowns, increased maintenance costs, and safety risks.

Heat-resistant conveyor belts address these challenges by:

  • Maintaining flexibility at elevated temperatures

  • Resisting thermal oxidation and cracking

  • Preserving strong adhesion between rubber and carcass

  • Ensuring stable conveying performance

Selecting the correct heat-resistant conveyor belt significantly improves system reliability and production efficiency.

Belt Construction and Material Design

Heat-resistant conveyor belts are constructed with carefully selected materials and optimized designs to withstand thermal stress.

Heat-Resistant Top Cover Rubber

The top cover rubber is formulated with heat-resistant compounds that resist thermal aging and surface degradation. Depending on application requirements, different grades of heat resistance are available, allowing the belt to handle varying material temperatures. The rubber remains flexible and crack-resistant even after long-term exposure to heat.

Reinforced Carcass Layer

The carcass layer provides the belt’s tensile strength and load-bearing capacity. Common reinforcement materials include EP (polyester/nylon) fabric, NN (nylon/nylon) fabric, and steel cord for heavy-duty applications. Proper bonding between rubber and fabric ensures stability under both mechanical and thermal stress.

Bottom Cover Rubber

The bottom cover rubber protects the belt from wear caused by rollers and pulleys. It is also heat-resistant to prevent deformation and maintain smooth belt operation.

Heat Resistance Grades and Classifications

Heat-resistant conveyor belts are available in different grades based on the maximum temperature of the conveyed material and operating conditions.

  • Moderate Heat-Resistant Belts
    Suitable for material temperatures up to approximately 120°C–150°C.

  • High Heat-Resistant Belts
    Designed for continuous operation at material temperatures up to 200°C.

  • Extra High Heat-Resistant Belts
    Used for extreme applications where material temperatures may reach 300°C–400°C intermittently.

Choosing the correct grade is essential to ensure optimal belt life and performance.

Technical Parameters and Specifications

Heat-resistant conveyor belts can be manufactured according to specific customer requirements. Typical specifications include:

  • Belt Width: 400 mm – 2400 mm

  • Belt Length: Customized

  • Tensile Strength: 160 N/mm – 2500 N/mm

  • Number of Plies: 2 – 8 plies

  • Top Cover Thickness: 4 – 10 mm

  • Bottom Cover Thickness: 2 – 6 mm

  • Maximum Material Temperature: Up to 400°C (depending on grade)

  • Operating Temperature: -20°C to +150°C

  • Elongation at Break: ≤ 10%

All belts are tested to ensure consistent heat resistance and mechanical performance.

Performance Advantages

Heat-resistant conveyor belts provide a combination of thermal stability and mechanical durability.

They resist surface hardening and cracking caused by heat exposure, maintain strong adhesion between rubber and fabric, and offer excellent wear resistance. Their stable performance reduces unplanned downtime and minimizes maintenance frequency.

By extending belt service life, heat-resistant conveyor belts help lower total operating costs in high-temperature applications.

Typical Application Areas

Heat-resistant conveyor belts are widely used in industries where hot materials must be transported safely.

Cement Industry

Used for conveying clinker, hot limestone, and kiln discharge materials.

Steel and Metallurgy

Applied in sinter plants, coke handling, and hot slag conveying systems.

Power Plants

Used in ash handling systems and hot fuel transportation.

Mining and Mineral Processing

Used for transporting heated ores and processed minerals.

Chemical and Fertilizer Plants

Applied where high-temperature bulk materials are handled.

Installation Guidelines

Proper installation is critical to ensuring long-term performance.

Before installation, conveyor structures should be inspected for alignment and cleanliness. All rollers and pulleys must rotate freely. During installation, belt tension should be adjusted evenly to avoid excessive stress and heat generation.

After installation, a trial run without load is recommended to check tracking and system stability.

Operating Instructions

To maximize belt life, materials should be cooled as much as possible before conveying. Avoid continuous overloading and ensure even material distribution across the belt width.

Conveyor speed should be optimized to minimize heat accumulation, and belt slippage should be avoided to prevent additional frictional heat.

Maintenance and Service Recommendations

Regular inspection and preventive maintenance are essential.

  • Remove material buildup regularly

  • Monitor belt surface condition

  • Check belt tension and alignment

  • Inspect rollers and pulleys

Timely maintenance helps preserve heat resistance and prevents premature belt failure.

Common Problems and Solutions

Surface Cracking
Usually caused by excessive material temperature or incorrect belt grade selection.

Cover Hardening
May result from prolonged exposure beyond design temperature limits.

Delamination
Often caused by improper installation or poor belt-pulley alignment.

Selecting the correct heat-resistant grade and maintaining proper operating conditions can prevent these issues.
