Technical Questions
What is the difference between T1, T2, T3 and T4 heat resistant belts?
T1 handles up to 100C continuous (125C peak), T2 up to 125C (150C peak), T3 up to 150C (180C peak) and T4 up to 200C (400C peak). Selection depends on material temperature, lump size and conveyor length, because a short conveyor gives less cooling time.
Can a heat resistant belt be spliced on site?
Yes. Hot vulcanization with matching high-temperature tie gum is recommended. Cold bonding cements are restricted in high-temperature zones because the bond degrades faster than the cover.
How long does a heat resistant conveyor belt last in cement service?
Typically 12 to 24 months on clinker lines. Cover compound, cooling zone length and idler spacing are the main life factors. Reducing idler spacing by 10 to 15 percent in hot zones extends carcass life.
What is the minimum pulley diameter for a heat resistant belt?
Minimum drum diameter follows ISO 3684 and the carcass rating. As a rule, at least 125 times the total EP fabric thickness. Undersized pulleys cause ply separation under thermal load.

Heat Resistant Conveyor Belt Temperature Grades (T1-T4)
| Grade | Continuous Temp | Peak Temp | Cover Compound | Typical Application |
|---|---|---|---|---|
| T1 | Up to 100C | 125C | SBR / NR | Aggregate, grain, fertilizer |
| T2 | Up to 125C | 150C | Heat-resistant SBR | Cement clinker, foundry sand |
| T3 | Up to 150C | 180C | EPDM | Cement clinker, chemical ash |
