Description
Purpose
Heat-resistant conveyor belts are mainly used for conveying high-temperature materials, such as sintered hot coke, cement clinker, and hot castings. EPDM or SBR is used as the cover rubber depending on the main properties, damage conditions, loss of conveying capacity, and different heat resistance grades of the heat-resistant belt. 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 to improve the service life of the heat-resistant belt. It can be made into a circular belt according to customer requirements.
Heat-resistant and high-temperature conveyor belts are widely used in material conveying in coal, mining, port, metallurgy, power, and chemical industries.
Features
1. High strength, thin and lightweight.
2. Uses EP rubber-coated canvas as the carcass material.
3. The belt is soft, has a good trough shape, and good elasticity.
4. Impact resistant, wear-resistant, and corrosion-resistant.
5. Suitable for high-load, high-speed, and medium-to-long distance material conveying.
6. Stable operation, no deviation.
