Description
Heat Resistant Conveyor Belts Features:
Suitable for conveying hot material like powder or clump materials at high temperature.
Ideal for conveying sintered ores, cokes, soda ash, chemical fertilizer, 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.
Heat resistant conveyor belt can be divided into three types according to working temperature range: HRT-1 =100℃, HRT-2=125℃, HRT-3=150℃
High Temperature Resistant Conveyor Belts Features:
The belt carcass of this product is EP fabric of high modulus, low shrink, and high breaking tensile strength.
Cover rubber of this product uses EPDM rubber or chlorobutadiene rubber that has very good high temperature resistance.
The belt is made with extra care after mixing rubber with high temperature resistant materials, assembling and vulcanizing.
The belt can bear 250℃ even 500℃ high temperature for a short time.
It is suitable for use in cement, metallurgical and steel industry.
