ISO340 Fire-resistance and ISO284 Anti-static Solid Woven Conveyor Belt For Coal Mining
Fire resistant conveyor belts are primarily needed for internal transportation within tunnels and mines .Durability In environments where coal dust, gas, fertilizer or other combustible materials are involved there are chances of fire hazards.
It is essential that the conveyor belts being used cannot create static electricity that can ignite gases and dust in the atmosphere. A very important safety feature of Beltcon Fire resistant conveyor belts is that they are anti-static and conform to numerous safety classifications and international standards also possess self-extinguishing design and prevent fire from spreading over the entire belt .by using FR belt we can reduce the maintenance of conveyors, which are prone to be damaged by flame at the blast furnaces of iron works.
Solid woven PVG solid woven fire-resistance conveyor belt
The belt with multi-plies solid woven structure carcass, after whole plastic fire-resistance plaster dipping, is manufactured though high temperature plastication (named PVC solid woven fire-resistance conveyor belt) or after sticking the cover of the fire-resistance rubber/plastic, vulcanizing by flat bed press (named PVG solid woven fire-resistance conveyor belt).
The Physical properties and safety data of PVC and PVG solid woven fire-resistance conveyor belts all equally are up to MT147-1995 standard.
