Product Information
Heat resistant (high temperature resistant)conveyor belt is a specialized protective conveyor belt for transporting high-temperature materials such as metallurgy and building materials. It is formed through a special vulcanization process and can withstand high-temperature material baking and heat radiation for a long time. It is the core accessory for material transportation in high-temperature conditions.
Performance characteristics:
1. High strength and low shrinkage polyester canvas, cotton canvas, polyester cotton canvas, etc. are used as the skeleton layer.
2. The upper and lower surfaces are covered with a certain thickness of high-temperature or heat-resistant rubber.
Suitable for the transportation of sintered ore, coke, cement clinker particles, powders, blocks and other materials in industries such as metallurgy and building materials
