Fire resistant rubber conveyor belts are conveyor belts made of multi-layer polyester-cotton cloth or polyester canvas covered with heat-resistant glue and bonded together by high temperature vulcanization. They are suitable for conveying hot coke, cement, slag and hot castings below 175℃. The covering rubber of fire resistant rubber conveyor belts will produce a microporous carbonized layer when encountering high temperature, which is fireproof and resistant to combustion, which can prevent further heat transfer to the belt body and reduce the internal strength of the belt. The carbonized layer will produce irregular small cracks during the operation of the belt body, which is used to cool the belt body. The unique formula design of fire resistant rubber conveyor belts solves the key problems of high saturation, poor adhesion, and low adhesion between layers of ethylene-propylene rubber. It has the characteristics of light belt body, long life, and good heat resistance.

Application of fire resistant rubber conveyor belts in the industrial field：

1. Cement industry: The cement industry is the largest application market for fire resistant rubber conveyor belts. Fire resistant rubber conveyor belts can be used in the export of clinker coolers, because the temperature of the clinker just coming out of the rotary kiln is particularly high, sometimes it can even reach more than 1000℃. After the cooling machine, the temperature is still between 80 degrees Celsius and 200 degrees Celsius, so the conveyor belts used in the cement industry need to withstand the high temperature of the clinker, and the heat resistance of the heat resistant conveyor belt perfectly meets this requirement.

2. Iron and steel metallurgical industry: heat resistant conveyor belt is usually used in the transportation process of sintering machines, ring chillers, rotary kilns and other equipment, often conveying sintered ore, pellet ore, coke, blast furnace slag, steel slag and other high-temperature materials. The wear-resistant characteristics of the heat resistant conveyor belt can meet the needs of the steel and metallurgical industry.

3. Chemical industry: heat resistant conveyor belt can transport dried chemical raw materials, fertilizers, soda ash, sulfur and calcined products in the chemical industry. In the chemical industry, it is sometimes necessary to transport some corrosive chemicals, which need to be transported with corrosion-resistant characteristics.

The heat resistant conveyor belt produced by Liaoning Hengyi Rubber Machine Belt Manufacturing Co., Ltd. adopts special manufacturing processes and materials, which have good oxidation resistance. Even in a long-term high temperature environment, the strength will not be reduced or deteriorated due to oxidation, the size can be maintained stable, and the normal use will not be affected by deformation or shrinkage. The heat resistant conveyor belt we produce can work normally in corrosive media such as acids and alkalis, has strong corrosion resistance, and can withstand direct contact combustion of metals, minerals, or other high-temperature materials.

Liaoning Hengyi Rubber Machine Belt Manufacturing Co., Ltd. passed the IS09000 standard certification, IS09001 quality management system certification, IS014001 environmental management system and OHSAS18001 occupational safety and health management system standard certification in 2021, and obtained the AAA credit enterprise certification. The company has complete testing methods and excellent domestic testing equipment to ensure that every product produced meets industry standards. If you are interested in our heat resistant conveyor belt, please feel free to contact us, we look forward to talking to you!
