BOTON PYROGUARD™ SERIES

Heat-Resistant Conveyor Belts

Heat resistance is where BOTON began. When BOTON was founded in 2000, heat-resistant conveyor belts were chosen as one of the company’s defining product directions, helping the young company establish itself in demanding metallurgical applications from its earliest years.
Today, BOTON heat-resistant and high-temperature conveyor belts are engineered for clinker, sinter, slag, hot ash and other thermally demanding bulk materials, with belt construction selected according to material temperature, particle size, contact time, impact conditions and conveyor configuration.

Heat-Resistant Conveyor Belt FAQs

What temperature can a heat-resistant conveyor belt handle?

There is no single temperature limit for all heat-resistant conveyor belts. Material temperature, belt surface temperature and carcass temperature are different parameters, and allowable conditions also depend on the cover compound, carcass structure, particle size, exposure time and conveyor operating conditions. BOTON therefore selects heat-resistant belt systems according to the complete application rather than one temperature figure.

What information is needed to select a heat-resistant conveyor belt?

Key information includes conveyed material, maximum and typical material temperature, particle size, conveyor length, belt speed, loading conditions, impact level, expected stoppages and operating environment. Belt surface and carcass temperature data, if available, can further improve selection accuracy.

Why is loaded stoppage critical in high-temperature conveying?

When a conveyor stops while carrying hot material, heat continues to transfer into the belt while cooling by belt movement is reduced. This can rapidly increase carcass temperature and may cause irreversible damage, particularly in heat-sensitive fabric structures.

How important is the cover compound in a heat-resistant conveyor belt?

The cover compound is a primary thermal protection layer. Its resistance to heat aging, hardening, cracking and abrasion directly affects belt life. Carcass structure and thermal protection layers must then be matched to the temperature profile and operating conditions.

When should an aramid heat-resistant conveyor belt be considered?

Aramid carcasses are suitable for demanding high-temperature applications where high strength, low weight, thermal stability and resistance to heat-related degradation are important. They can be particularly useful for complex conveyor routes and applications involving very hot sinter, slag or similar materials.

When is an IW reinforced belt preferred over a conventional fabric belt?

IW reinforced belts are suited to applications where high temperature is combined with severe impact, cutting or puncture risk. The steel-wire mesh helps resist impact and burn-through while also supporting heat dissipation.
