Flame Resistant Conveyor belts
Flame Resistant Conveyor Belts for underground coal mines.
Flame Resistant rubber belting features: the belt is not removed, the elongation is small, the impact resistance, the tear resistance.
The type can be divided into PVC type (plastic surface), flame retardant belt coal mine special supplier + conveyor belt manufacturer PVG type (rubber face attached to PVC) solid woven flame Resistant belts to implement the mt914-2002 standard.
PVC fire Resistant Conveyor Belts is suitable for drying conditions of the dip Angle of less than 16 degrees.
Fire Resistant Conveyor Belts
It have steel cord conveyor belt and PVC PVG conveyor belt for used in up and down the pit. And Self-extinguishing conveyor belt designs prevent fires from spreading over the entire belt. Fire retardant conveyor belt designs protect the belt from attack by hot materials that could otherwise reduce its service life.
Fire retardant belt features:
High tensile strength: suitable for large span and long distance conveying materials.
Use stretch small: the required drawing is short.
The diameter of the driving roller is small: the salary has a longitudinal arrangement of steel wire rope and fatigue, so it can be equipped with a small diameter roller, which is a compact device.
Rubber and steel wire rope good adhesion:
galvanized steel wire rope surface, at the same time adopt has good adhesion performance of rubber with steel wire rope, and rope together, impact resistance, not easy impellers, long service life.
Steel cord belting tension even: due to the advanced manufacturing process, the wire rope is arranged evenly, the tension is consistent, and the balance is not easy to run.
Good groove performance:
the core has no transverse skeleton, easy to form deep groove shape, multi – loading material, and prevent the scattering.
fire retardant conveyor belt TESTING
We test underground coal mine conveyor belts to determine if they are safe to use in these potentially hazardous environment.
Fire retardant belt accessories such as scrapers, skirting, liners and lagging materials can also be tested for fire-resistant and anti-static properties.
Our facilities for flame Resistant belts testing include:
- a fire gallery
- a drum friction test rig
- electrical resistance and laboratory flame equipment
- tensile machines.
TESTS
We can do the belts according to Self-extinguishing conveyor belt tests:
- AS 1334.1 (conveyor and elevator belting)
- AS 1334.2 (determination of thickness of belting and rubber covers across the width)
- AS 1334.2A (determination of thickness of belting and rubber covers across the width)
- AS 1334.9 (determination of electrical resistance of conveyor belting )
- AS 1334.10 (conveyor and elevator belting)
- AS 1334.11 and AS 1334.12 (conveyor and elevator belting)
- AS 4606-2012 (Grade S fire resistant and antistatic requirements for conveyor belting and conveyor accessories)
- BS 2050
Self-extinguishing conveyor belt TESTS
We carry out type tests for underground coal mining applications to AS 4606, and other tests to parts of AS 1334.
Type tests we carry out include:
- AS 1332 (conveyor belting- textile reinforced)
- AS 1333 (conveyor belting of elastomeric and steel cord construction)
- AS 1334 methods 1 to 12 (conveyor and elevator belting)
- AS 1683.11 (tension testing of vulcanized or thermoplastic rubber)
- BS 2050 (specification for electrical resistance of conducting and antistatic products made from flexible polymeric material)
- Method A4.1 and A4.2
- AS 4606 (Grade S fire resistant and antistatic requirements for conveyor belting and conveyor accessories)
We may also be able to test to other standards or carry out similar tests if required.
DRUM FRICTION TEST
The drum friction test simulates a belt slipping over a jammed pulley, or a pulley rotating under a stationary conveyor belt. This measures whether the surface temperature remains under a required maximum after a specific time and under a specific tension.
Generally a rubber conveyor belt can produce a pulley surface temperature of up to 500°C (930°F). The visual appearance of flame or glow is not permitted.
SURFACE RESISTANCE TEST
An electrostatic charge may build up on the conveyor belt surface and ignite a mixture of flammable gases and air.
Therefore the surface resistance of the conveyor belt covers has to be below 300 MOhms.
HIGH-ENERGY PROPANE BURNING TEST
Conveyor belt must not conduct fire. In order to determine whether a conveyor belt fulfills this requirement, it is ignited by a propane burner. After the ignition source has been removed, the flames must self-extinguish within a certain time frame or within a certain distance. A typical sample for this test is 2 m long at full width.
LABORATORY GALLERY TEST
A small scale version of the Propane Burner Test, first described in DIN 22118.
