Fabric Conveyor Belt, Heat Resistant Conveyor Belt，High Temperature Conveyor Belt Supplier
1. Applications
Heat resistant conveyor belt is suitable for transporting high temperature materials, such as sintering ore, hot coke, cement clinker, hot casting, etc. According to heat resistant grade of different working conditions, we use EPDM or SBR as cover rubber and use high-strength EP or cotton canvas as tension element.
2. Heat resistant grade
Four grades divided according to different testing temperatures:
Grade |
Testing temperature(≤) |
T1 |
100℃ |
T2 |
125℃ |
T3 |
150℃ |
T4 |
175℃ |
