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.
