Product features:
1. Suitable for conveying hot material like powder or clumpmaterials at high temperature.
2. Ideal for conveying sintered ores, cokes, soda ash, chemicalfertilizer, slag and fundry.
3.It can resist high temperature.
4.The rubber compound used in the cover has been designed toavoide premature aging due to contact with any source of heat.
5. Heat Resistant conveyor belt can be divided into three typesaccording to working temperature range: HRT-1 ≤100°C, HRT-2≤125°C,HRT-3≤150°C.
Models:
Heat resistant conveyor belts fall into threemodels
Mode1: able to with stand the test temperature of less than 100°C,code S1
Mode2: able to with stand the test temperature of less than 125°C,code S2
Mode3: able to with stand the test temperature of less than 150°C,code S3
Mode4: able to with stand the test temperature of less than 175°C,code S4
