Usage
Polyester conveyor belts (EP conveyor belts) are widely used in industries such as coal, mining, ports, metallurgy, power generation, and chemical processing for material transportation.
Function
1. High strength, thin strip, lightweight.
2. The skeletal material is canvas coated with EP rubber.
3. This belt is soft, features excellent groove-fitting performance, and has good elasticity.
4. Impact-resistant, wear-resistant, and corrosion-resistant.
5. Suitable for material transportation involving heavier loads, higher speeds, and medium-to-long distances.
6. Runs stably with no deviations.Specifications and Technical Parameters
