Flame Retardant Steel Cord Conveyor Belt

MT668–2008 certified flame retardancy meets steel cord tensile performance — for long-span, high-speed bulk material conveying where fire safety compliance is required.

Coal Mine Main Haulage

The primary application — long conveyor routes in and around coal mining operations where MT668–2008 certification is required but mandatory underground anti-tear classification does not apply.

Thermal Power Plant Fuel Conveying

High-speed, long-distance coal delivery systems at power stations where flame retardant belt classification is a facility safety requirement.

Open-Pit Mining & Quarrying

Above-ground conveyor systems in mining operations handling coal, ore, or aggregate where fire risk classification requires certified FR belting.

Ports & Bulk Terminals

Ship unloading, stockyard, and reclaim conveyor systems handling flame-risk bulk commodities requiring certified fire safety equipment.

High-Speed, Long-Distance Conveying with Certified Flame Retardancy

The Flame Retardant Steel Cord Conveyor Belt is purpose-built for high-throughput bulk material conveying environments where flame retardancy is a regulatory or operational requirement — and where only a steel cord core can deliver the tensile strength, low elongation, and service life the application demands.

Ideal for large-span, high-speed, high-capacity conveyor systems in coal mines, power plants, ports, and other bulk handling facilities where both long-distance performance and flame retardancy certification are simultaneously required.

What MT668–2008 Flame Retardancy Actually Means

The flame retardant properties are built into the rubber cover compound during mixing — not applied as a surface coating or post-production treatment
Both top and bottom cover compounds are independently formulated to meet MT668–2008 flame propagation and self-extinguishing requirements

Anti-static performance is similarly compound-level, ensuring consistent surface resistance values throughout the belt’s service life regardless of surface wear
Open-structure rope core with full rubber infiltration means the internal belt structure does not contain untreated voids where moisture or combustible gases could accumulate

Key Features

Anti-tear mesh, certified flame retardancy, and steel cord tensile strength — all in a single underground-rated belt.

Built-In Anti-Tear Mesh Layer

One or two layers of steel wire or woven fabric mesh embedded between cover and core — physically prevents foreign object penetration.

Certified Flame Retardant

HG/T3646—1999 compliant; mandatory requirement for underground main gate.

Anti-Static

Continuous static dissipation to eliminate ignition risk in dust-laden and methane-present underground environments

Ultra-High Tensile Strength

Steel wire rope core supports ST630–ST5000 tensile grades for long-distance, high-load conveying routes

Long-Distance Capability

Engineered for main haulage systems spanning hundreds to several thousand meters in a single flight

Foreign Object Penetration Resistance

Anti-tear mesh intercepts tramp metal, rock fragments, and sharp material before they can split the belt longitudinally

High Splice Integrity

Open-structure rope core with full rubber infiltration ensures maximum vulcanized splice strength and longevity

Excellent Troughing

Steel rope core forms a consistent trough profile that transitions smoothly to flat, reducing edge wear

Application Scenarios

Engineered for Demanding Industrial Environments

Why Underground Operations Specify minsenmine

HG/T3646—1999 Certified Production

Every flame retardant steel wire rope core belt we manufacture is tested and documented to HG/T3646—1999. Compliance certificates and full quality records ship with every order — ready for mine safety inspection.

Anti-Tear Mesh Integrated in Manufacturing

The mesh layer is not a post-production addition. It is laid and vulcanized into the belt structure during the primary manufacturing process, ensuring consistent bond strength between mesh, cover, and core throughout the full belt length.

Configurable Protection Level

Single or double mesh layers, steel wire or woven fabric mesh type — specified to your loading conditions and foreign object risk profile. We work with your engineering team to determine the right configuration before production begins.

Factory Direct from Shandong

No intermediaries. Direct manufacturing lead times, competitive factory pricing, and a single point of contact from specification through delivery.

FAQ

Is this belt mandatory for underground coal mine installations?

In China, underground coal mine conveyor belts must comply with mandatory flame retardancy and anti-static standards under coal mine safety regulations. The Flame Retardant Steel Wire Rope Core belt (HG/T3646—1999) meets these requirements for underground main haulage applications.

What is the difference between steel wire mesh and woven fabric mesh anti-tear layers?

Steel wire mesh provides higher interception strength against hard metallic foreign objects and is recommended for installations with significant tramp metal risk, such as near shearer or continuous miner operations. Woven fabric mesh offers good tear resistance with slightly less weight and better belt flexibility, suitable for applications where the primary risk is rock fragments or fibrous material.

Can I use one mesh layer instead of two?

Yes. Single-layer mesh is standard for most applications and provides substantial protection against penetration. Double-layer mesh is specified for particularly high-risk loading conditions or where the consequences of belt failure are severe enough to warrant the additional investment.

How does the anti-tear mesh affect the splicing procedure?

The mesh layers are accommodated in the splice step calculation. Vulcanized splicing is required and the step pattern must account for mesh layer positions to ensure full strength is achieved.

What tensile grade do I need for my underground main haulage system?

Tensile grade depends on conveyor length, belt width, load per meter, drive power, and installed take-up. Provide us your conveyor layout data and we will calculate the minimum required tensile grade and recommend a specification.

Do you supply the belt with full compliance documentation?

Yes. Every belt ships with the production test report, material certificates, and HG/T3646—1999 compliance documentation. These records are available for submission to mine safety inspection authorities.
