High Temperature Flame Resistant Conveyor Belt For Cement Mining Coal Industries

1.  Specialized Materials:

    Carcass (Reinforcement): Typically made from high-tensile strength, heat-stabilized synthetic fabrics like EP (Polyester-Nylon) or, for extreme temperatures, steel cords. These materials are treated to resist thermal degradation.

    Top & Bottom Cover: The most critical component. Made from compounded rubber formulations—often EPDM (Ethylene Propylene Diene Monomer) or SBR (Styrene-Butadiene Rubber) with specific additives. These compounds are designed to resist cracking, hardening, and abrasion caused by heat.

    Insulating Layer: Many belts include a heat-insulating fabric or rubber layer between the carcass and the top cover to shield the tension-bearing carcass from the direct impact of heat.

2.  Temperature Resistance:

Belts are graded for specific temperature ranges. Common classifications include:

        T1 (up to 100°C / 212°F): For moderately hot materials.

        T2 (up to 125°C / 257°F): A common standard for many applications.

        T3 (up to 150°C / 302°F): For high-temperature duties.

It's crucial to distinguish between material temperature and ambient air temperature when selecting a belt.
