Reliable Fire-Safe Conveyor Belt Solution for High-Risk Industrial Environments
Flame-retardant conveyor belts are specially engineered rubber conveyor belts designed to prevent fire propagation and reduce fire hazards in high-risk industrial environments. In industries such as mining, power generation, cement production, steel processing, and bulk material handling, Conveyor Systems often operate under conditions where heat, friction, sparks, or combustible materials are present. Under such circumstances, ordinary conveyor belts may ignite or allow flames to spread rapidly along the conveying line, creating serious safety risks and potential production losses.
Flame-retardant conveyor belts are developed using advanced fire-resistant rubber compounds and reinforced structural designs that significantly reduce flammability, slow flame spread, and improve overall system safety. These belts play a critical role in protecting personnel, equipment, and facilities, while ensuring stable and continuous material transportation.

A flame-retardant conveyor belt is a type of industrial conveyor belt that resists ignition and limits flame propagation when exposed to fire sources such as open flames, sparks, or high temperatures. Unlike standard rubber conveyor belts, flame-retardant belts are formulated with special additives and rubber compounds that self-extinguish once the flame source is removed.
These conveyor belts are commonly required by safety regulations in underground mines, coal handling systems, thermal power plants, and enclosed industrial environments where fire risks must be strictly controlled.
Conveyor belts often run continuously for long periods, generating friction and heat at contact points such as rollers, pulleys, and drive drums. In dusty or confined environments, accumulated materials may further increase fire risk. Once a conveyor belt catches fire, flames can spread quickly along the belt length, causing severe damage and safety hazards.
Flame-retardant conveyor belts significantly reduce these risks by:
Preventing flame spread along the belt surface
Minimizing smoke generation
Maintaining structural integrity under heat exposure
Improving emergency response time
Using flame-retardant conveyor belts is not only a safety measure but also a regulatory requirement in many industries.
Flame-retardant conveyor belts consist of three main components: top cover rubber, carcass reinforcement layer, and bottom cover rubber.
The top cover rubber is formulated with fire-resistant compounds that resist ignition and suppress flame propagation. When exposed to fire, the rubber surface chars rather than burns aggressively, reducing flame spread and heat release. Depending on application requirements, the top cover can also provide abrasion resistance, oil resistance, or chemical resistance.
The carcass layer provides tensile strength and load-bearing capacity. Common reinforcement materials include EP fabric (polyester/nylon), NN fabric (nylon/nylon), solid woven fabric, and steel cord for heavy-duty applications. Strong adhesion between rubber and fabric ensures structural stability even under heat stress.
The bottom cover is also flame-retardant and protects the carcass from wear caused by conveyor rollers and pulleys. It maintains flexibility and ensures smooth belt operation and proper tracking.

Flame-retardant conveyor belts are manufactured to meet various international safety standards. Common classifications include:
General Flame-Retardant Conveyor Belts
Suitable for surface conveying systems and open environments.
Underground Mining Flame-Retardant Conveyor Belts
Designed for enclosed spaces with strict fire safety requirements.
Fire and Abrasion Resistant Conveyor Belts
Combine flame resistance with high wear resistance for harsh working conditions.
Depending on the market and application, belts can comply with ISO, DIN, EN, MSHA, or other regional standards.
Flame-retardant conveyor belts can be customized to meet specific industrial requirements. Typical technical parameters include:
Belt Width: 400 mm – 2400 mm
Belt Length: Customized
Tensile Strength: 160 N/mm – 2000 N/mm
Number of Plies: 2 – 8 plies
Top Cover Thickness: 3 – 10 mm
Bottom Cover Thickness: 1.5 – 6 mm
Operating Temperature: -20°C to +120°C (higher grades available)
Elongation at Break: ≤ 10%
Flame Retardancy: Self-extinguishing after flame removal
All belts undergo rigorous testing to ensure compliance with flame-retardant performance requirements.

Flame-retardant conveyor belts offer multiple performance advantages beyond fire safety.
They provide excellent resistance to ignition, ensuring that small sparks or localized heat sources do not result in uncontrolled fires. The belts maintain stable mechanical properties under heat exposure, preventing sudden failure. High abrasion resistance ensures durability when handling sharp or heavy materials, while good flexibility supports smooth belt tracking.
By reducing fire risk and downtime, flame-retardant conveyor belts contribute to safer and more efficient material handling operations.
Flame-retardant conveyor belts are widely used in industries where fire safety is critical.
Used extensively in underground coal mines and mineral processing plants where combustible dust and confined spaces present high fire risks.
Applied in coal handling systems, ash conveying, and fuel transportation areas.
Used in clinker transport and high-temperature material handling zones.
Installed in raw Material Handling Systems where sparks and heat are present.
Used for bulk cargo handling involving coal, coke, and other flammable materials.
Proper installation is essential for ensuring the flame-retardant performance of conveyor belts.
Before installation, conveyor components should be inspected for alignment and cleanliness. Any sharp edges or damaged rollers should be repaired. During installation, belt tension must be adjusted evenly to prevent slippage and excessive heat generation.
After installation, a no-load trial run is recommended to verify tracking and system stability.
During operation, materials should be loaded evenly across the belt width to avoid localized overheating. Conveyor speed should match system design and material flow rate. Operators should avoid prolonged belt slippage on pulleys, as excessive friction can generate heat.
Regular monitoring helps identify abnormal conditions early and prevents safety incidents.
Routine maintenance is critical for maintaining flame-retardant performance.
Regularly clean material buildup and dust
Inspect belt surface for damage or abnormal wear
Check pulley lagging and belt tension
Maintain proper conveyor alignment
Good housekeeping and preventive maintenance significantly reduce fire risk and extend belt service life.
Excessive Heat Generation
Often caused by belt slippage or misalignment. Adjusting tension and alignment resolves the issue.
Surface Wear
May result from abrasive materials. Selecting thicker covers or abrasion-resistant flame-retardant belts helps.
Loss of Flame Retardancy
Occurs if non-approved materials or repairs are used. Always use certified flame-retardant belts and accessories.
Selecting the correct flame-retardant conveyor belt requires evaluating fire risk level, operating environment, conveyed material properties, load capacity, and applicable safety standards. Consulting with an experienced conveyor belt manufacturer ensures compliance and optimal performance.
