Heat Resistant Conveyor Belt

Product Features:

  • Suitable for conveying hot material like powder or clump materials at high temperature.
  • Ideal for conveying sintered ores, cokes, soda ash, chemical fertilizer, hot limestone, cement clinker, slag, and foundry.
  • It can resist high temperature.
  • The rubber compound used in the cover have been designed to avoid premature aging due to contact with any source of heat.

Choosing a suitable heat resistant belt:

  • Type of carried material
  • Shape of carried material
  • Lump size of carried material
  • Temperature of carried material
  • Surface temperature of the belts
  • Belt speed, etc.
