  • The surface temperature of heat resistant conveyor belt varies with the material type, belt speed, loading rate and size depending on circumstance condition.
  • In order to select the proper heat resistant conveyor belt, it is necessary to consider not only the material temperature to be conveyed but also the surface temperature of conveyor belt.
  • Characteristics required for heat resistant conveyor belt are as follows:
    1. Rubber cover and carcass should not deteriorate due to heat.
    2. Rubber cover and carcass should maintain durability, even at high temperatures.
    3. Rubber cover and carcass should maintain good adhesion form on unit even when they are exposed to high temperatures.
