Product Description
Fire Resistant conveyor belt, also called flame-resistant conveyor belts, manufactured is using Nylon carcass/EP carcass material, suitable for conveying materials that require a flame resistant and static conductive belts in power, chemical, light, metallurgical and grain processing industries, under the condition of flammable or explosive environment above coal mines.
Belt Fire Resistant Capability Test
Features
- Self-extinguishing design and prevent fire from spreading over the entire belt educe maintenance requirements of conveyors that are prone to damages by flame at blast furnaces.
- Belts meeting various testing standards according to ISO like flame test, electrical resistance test, drum friction test.
- Flame-resistant properties.
- Superior tensile strength.
- Resistant to high heat & wear.
- Capability to deliver superior performance under extreme temperatures.
- Good abrasion resistant and anti-static features.
How to Order
When selecting flame-retardant conveyor belts, understanding the customer's usage environment is crucial. Conveyor belts are used in a variety of settings, from dust-laden factory workshops to explosive environments like mines, as well as in complex outdoor and underground operations. Different scenarios impose different requirements on the flame-retardant properties of conveyor belts. Therefore, scientifically analyzing these environmental conditions, combined with the anti-static and flame-retardant properties of the conveyor belt, ensures safety and efficiency.
Currently, there are three main types of fire-resistant conveyor belts: fabric-layered fire-resistant conveyor belts, steel cord conveyor belts, and solid woven conveyor belts. Among the three types of fire-resistant conveyor belts used in coal mines, the fabric-layered conveyor belt is the most widely used, accounting for over 80% of the market share. It offers stronger flame retardancy while being lighter and more cost-effective.
