Combusition-resistant steel cord converyor belt for coat mining
1. Configuration
The combustion-resistant steel cord conveyor belt for coal mining is using the higher strength, less elongation galvanized steel cord, which top and bottom burface are covered with combustion-resistant & anti-static rubber. The configuration is molded in invariable tensile. It can convey materials in conbustion-resistant and anti-s tatic environment after being vulacnized.
2. Application
The belt has excellent performance such as fire-resistance anti-static performance, high strength, longevity, less slongation, good flexibility. It is suitable for conveying materials at the occasion of long distance, high span, large load, and high strength in fire-resistance antistatic environments.
3. Specification
Intensity: 630m/mm~4000n/mm
Width: 800mm~2000mm
4. Safety Character
4.1 Drum friction test
During drum friction test, any part of test samplr shall or show any sign of flame or glow. The surface temperature of drum shall be less than 325º C.
4.2 Combustion best with ethanol blowrorch
Average burming time with/without flame for six test samples with full covering shall be not more than 3s after ethanol burmer moving away. Each individual sample's burning time with/without flame shall be not more than 10s in the same condition Average burning time with/without flamr for six test sampkes with full covering shall be not more than 5s after ethanol burner moning away. Eavh indicidual sample's buring time with/without flame shall be not more than 15s in the same condition.
4.3 Laneway Propane buring test.
Length that is completely undanmaged by flame shallby fllame shall be more than 250mm.
