Uses

The heat-resistant conveyor belt is mainly used for conveying high-temperature materials, such as sinter hot coke, cement clinker, hot castings, etc. According to the main performance of heat-resistant belt damage and loss of conveying capacity and different heat-resistant levels, EPDM or SBR are used as covering rubber respectively. High-strength and high-permeability polyester canvas or cotton canvas is used as strong layer. Heat-resistant glass cloth can be laid between the covering glue and the skeleton to improve the service life of the heat-resistant belt. According to customer requirements, can be made into a ring belt.

Heat resistant and high temperature resistant conveyor belt is widely used in coal, mining, port, metallurgy, electric power, chemical industry and other fields to transport materials.

Features

1. High strength, thin belt and light weight.
2. Use EP dipped canvas as skeleton material.
3. The belt body is soft, the groove is better, and the elasticity is better.
4. Impact resistance, wear resistance, corrosion resistance.
5. Adapt to large load, fast speed and medium and long distance material transportation.
6. Smooth operation, no deviation.
