Fire-resistant, flame-retardant, and scorch-resistant conveyor belt

Fire-resistant, flame-retardant conveyor belts are suitable for conveying materials in high-temperature environments in the metallurgical, cement, and chemical industries. They are mainly used to convey high-temperature solid materials such as sintered ore, coke, and cement clinker. In coal mines, using fire-resistant (also known as flame-retardant) conveyor belts helps reduce the incidence of above-ground and underground fires. Coal mine operating environments are relatively complex, with many hazardous factors such as coal dust and gas, and the coal being transported is itself a flammable substance. If electrical sparks are generated during transportation, it is easy to cause a fire. Using fire-resistant conveyor belts for coal mines can reduce the possibility of static sparks during coal transportation, and even if static sparks are generated, fire-resistant conveyor belts for coal mines have high flame retardancy and can maximize the flame spread time.

Experimental testing of fire-resistant, flame-retardant, and scorch-resistant conveyor belts

We test fire-resistant, flame-retardant, and scorch-resistant conveyor belts to determine if they can be safely used in these potentially hazardous environments.

Our fire-resistant, flame-retardant, and scorch-resistant belt testing facilities include:

• Drum friction testing machine
• Resistance and laboratory flame equipment
• Tensile testing machine.

Self-extinguishing conveyor belt test	Drum friction test	Surface resistance test	High-energy propane combustion test

The test requires exposing six independent belt samples to an open flame to cause them to burn. The flame source is then removed, and the burning time (flame duration) of the specimen is recorded. After removing the flame, airflow is directed at the specimen for a specified time, and the flame should not reignite. The time it takes for the belt sample to self-extinguish after removing the ignition source (flame) is then measured. The duration of continuous burning (visible flame) for each sample should be less than 15 seconds, and the maximum cumulative duration should not exceed 45 seconds.	The drum friction test simulates a belt slipping on a jammed pulley or a pulley rotating under a stationary conveyor belt. This test measures whether the surface temperature remains below a specified maximum temperature under a specific time and tension. Typically, the pulley surface temperature of rubber conveyor belts can reach up to 500°C (930°F). No flames or glowing visual appearance is allowed.	Static charges may accumulate on the surface of the conveyor belt and ignite a mixture of combustible gases and air. Therefore, the surface resistance of the conveyor belt cover must be below 300 megohms.	The conveyor belt must not conduct fire. To determine if the conveyor belt meets this requirement, a propane burner is used to ignite the conveyor belt. After removing the ignition source, the flame must extinguish itself within a certain time or distance. The typical sample full-width length for this test is 2 meters.

FAQ

Characteristics of Polyester Conveyor Belt

High modulus, low elongation, good heat stability, impact resistance and other characteristics, suitable for medium and long distance, high-speed, high-speed conditions of conveying materials.

Body material for heat-resistant conveyor belts

The subject material of the heat-resistant conveyor belt includes a skeleton material, a covering layer and a base material.

Selection of the diameter of the conveying roller

The selection of roller diameter should consider the following factors: the average specific pressure between the conveyor belt and the roller surface, the amount of deformation of the bag and the bag, the utilization rate of the allowable strength of the conveyor belt, the frequency of bending of the conveyor belt, the installation location of the conveyor and the conditions of use.

Main material of nylon conveyor belt

The main material of the nylon conveyor belt is nylon, but it does not have enough tension, so it is necessary to add a layer of industrial polyester cloth between nylon and nylon to increase the tension when making the finished product.

The advantages of the pattern conveyor belt

The pattern conveyor belt can ensure the smooth transportation of materials, with anti-skid, impact resistance, and high temperature resistance.
