Provide you with high-quality conveyor belt products and professional solutions
Purpose
• Heat-resistant conveyor belts are mainly used for conveying high-temperature materials, such as sintered ore, hot coke, cement clinker, and hot castings. According to the main manifestations of heat-resistant belt damage and loss of conveying capacity, and different heat-resistant levels, ternary ethylene propylene or styrene-butadiene rubber is used as the cover rubber; high-strength, high-permeability polyester canvas or cotton canvas is used as the reinforcing layer. Heat-resistant glass cloth can be laid between the cover rubber and the carcass layer to improve the service life of the heat-resistant belt. According to customer requirements, it can be made into a circular belt.
• Heat-resistant and high-temperature conveyor belts are widely used in coal, mining, ports, metallurgy, power, and chemical industries for material conveying.
Features
1. High strength, thin belt body, light weight.
2. Using nylon/EP polyester/NN/EE rubber-coated canvas as the carcass material.
3. The belt body is soft, has good troughing properties, and good elasticity.
4. Excellent high-temperature and heat resistance, can withstand 250°C high temperature for a short time.
5. Suitable for large loads, faster speeds, and medium and long-distance material transportation.
6. Stable operation, no deviation.
