Flame Resistant Conveyor Belt

Flame resistant conveyor belts are mainly used for internal transportation in high-safety-demand scenarios, including underground coal mines, tunnels, power stations, heating stations, garbage incineration plants, cement plants, foundries, and steel mills—ideal for conveying coal, coke, sintered ore, and flammable bulk materials.

Product Description

FAQ

In industries like underground mining, power generation, and bulk material handling where fire risk cannot be ignored, a conveyor belt must do more than just move materials—it must actively enhance operational safety. Our flame resistant conveyor belt is designed with this priority in mind, combining reliable conveying performance with certified fire protection. Built on a high-strength fabric carcass, it incorporates specially developed flame-retardant rubber compounds that help prevent flame spread and reduce ignition risks in hazardous environments. At the same time, the belt maintains excellent resistance to abrasion, wear, and mechanical stress, ensuring durability under continuous heavy-duty operation. With anti-static properties and stable performance across typical operating temperatures from -20℃ to +80℃, it is well-suited for transporting combustible materials such as coal and ores. Compared to standard conveyor belts, this solution strikes a smarter balance between safety, longevity, and efficiency—helping reduce downtime, lower maintenance costs, and meet strict industrial safety standards without compromising performance.

The flame resistant conveyor belt adopts a "flame resistant cover rubber + high-strength carcass + anti-static core rubber" structure, designed for explosion-proof safety

Flame Resistant Cover Rubber: Special rubber compound with flame retardant and anti-static additives, meeting MT668-2019 requirements—effectively inhibiting combustion and reducing smoke release.

Carcass: Optional high-strength zinc-plated steel cord (for heavy load) or multi-ply fabric (EP/NN/CC, for medium load), with low elongation and strong tensile resistance.

Core Rubber: Anti-static core rubber with good adhesion, ensuring tight bonding between carcass layers and preventing separation; surface resistance ≤3×10⁸Ω to avoid static accumulation.

Edge Reinforcement: Reinforced edge rubber resists wear and cracking, adapting to narrow tunnel conveyor layouts.

Features and Benefits

■ Excellent Flame Retardancy & Anti-Static

Meets MT668-2019: Alcohol combustion time (average ≤3s, single ≤10s), propane combustion damage length <1250mm, and surface resistance ≤3×10⁸Ω—fully avoiding static-induced explosion risks.

■ High Wear Resistance & Long Life

Special flame resistant cover rubber has Shore abrasion ≤90mm³, with service life 2x longer than ordinary mine belts; steel cord carcass (optional) resists impact from falling coal/ore.

■ Strong Tensile Performance

Steel cord type has tensile strength up to 7500N/mm, fabric type up to 400N/mm, suitable for long-distance (≥5km) underground coal transport.

■ Adaptability to Humid Mines

Cover rubber and core rubber have water absorption ≤1.5%, no performance degradation in wet underground environments (humidity ≥80%).

■ Reliable Splicing

Hot vulcanized splice is recommended; splice strength retains ≥90% of the original belt, ensuring stable operation without breakage in long-term use.

Q1:What is a flame resistant conveyor belt used for?

A1:

Flame resistant conveyor belts are designed for use in environments with fire risks, such as underground mining, power plants, and chemical industries. They help prevent flame spread and reduce fire hazards, ensuring safer material handling operations.

Q2:What standards do flame resistant conveyor belts comply with?

A2:

Flame resistant belts typically comply with international standards such as ISO, MSHA, DIN, and AS standards. These certifications ensure the belt can self-extinguish and limit flame propagation, making them suitable for hazardous environments.

Q3:How does a flame resistant conveyor belt work?

A3:

These belts are made with special rubber compounds that resist ignition and prevent flames from spreading. When exposed to fire, the material self-extinguishes once the ignition source is removed, helping to contain potential hazards.

Q4:Why can a flame resistant conveyor belt still get damaged or fail?

A4:

Failure can occur due to extreme heat beyond design limits, mechanical damage, poor maintenance, or improper belt selection. While flame resistant belts reduce fire risk, they are not completely fireproof and must be used within specified conditions.
