ZOOMRY
ZOOMRY fire resistant Conveyor Belts are manufactured using nylon carcass and EP carcass materials, finished with superior processes including calendering, assembling, and vulcanization. Compliant with ISO 340 (flame test) and EN 12882 fire safety standards, these belts are engineered to self-extinguish when the ignition source is removed — preventing flame propagation along the belt length in coal mines, power plants, and combustible material handling operations worldwide.
Why Are Fire Resistant Belts Critical for Safety?
In environments where combustible dust, flammable gases, or explosive atmospheres are present — coal mines, coal-fired power plants, biomass handling, and chemical processing — a standard conveyor belt can become a fire propagation pathway. If a bearing seizes, a pulley slips, or external heat ignites the belt surface, a non-fire-resistant belt will continue to burn and carry flame along the entire conveyor length — potentially igniting material stockpiles, transfer towers, and connected structures.
ZOOMRY fire resistant belts break this chain. The specially formulated rubber compounds and flame-retardant carcass construction ensure that once the ignition source is removed, the belt self-extinguishes — containing the fire at its origin and preventing catastrophic spread. For underground applications, the belts also incorporate anti-static properties that safely dissipate static electricity to ground, eliminating the risk of spark ignition in methane-rich atmospheres.
Where Are Fire Resistant Conveyor Belts Used?
Fire resistant belts are the mandatory choice wherever combustible materials are conveyed in enclosed or underground spaces, and wherever fire safety regulations require certified flame-retardant belt construction:
- Coal Mining — Surface & Underground: The primary application for fire resistant belts. Coal powder and methane gas create explosive atmospheres where belt fire resistance is mandatory by regulation. FR grade for surface, FRU grade for underground.
- Thermal Power Stations: Coal yard and fuel handling conveyors where combustible coal dust requires flame-retardant belt construction throughout the entire conveying route.
- Chemical & Fertilizer Plants: Conveying combustible chemicals, ammonium nitrate-based fertilizers, and materials with explosion hazards.
- Biomass & Wood Processing: Wood chips, pellets, sawdust, and agricultural residues — combustible materials that generate fine dust with explosion potential.
- Metallurgy & Grain Processing: Hot and combustible materials in blast furnaces, coal washing plants, and grain silos where dust explosion risks exist.
- Paper & Pulp, Sugar, Recycling: Industries where combustible material dust and processing byproducts create fire-hazard environments requiring certified belt safety.

Standard Features & Strengths
- Superior tensile strength: Nylon and EP carcass construction delivers high tensile ratings with excellent impact and tear resistance — even in underground conditions with high belt tensions.
- Flame retardant finishes: Belts comply with ISO 340 flame test, resistance test, and roller friction test — certified to self-extinguish and prevent fire propagation.
- Anti-static properties: FRU grade belts are electrostatically conductive, safely dissipating static charges to ground — preventing spark ignition in methane-rich and combustible dust atmospheres.
- High temperature and abrasion resistance: Belts withstand continuous material temperatures up to 80°C (FR) and 100°C (FRU) with excellent abrasion resistance for extended service life.
- Proven in critical environments: Leader in manufacture and export of fire resistant belts — trusted by coal mines, thermal power stations, coal washing plants, and combustible material handling operations worldwide.
