Heat Resistant Conveyor Belt
Product features:
A- Suitable for conveying hot material like powder or clump materials at high temperature.
B- Ideal for conveying sintered ores, cokes, soda ash, chemical fertilizer, slag and foundry.
C- It can resist high temperature.
D- The rubber compound used in the cover have been designed to avoid premature aging due to contact with any source of heat.
E- Heat resistant conveyor belt can be divided into three types according to working temperature range: HRT-1 ≤100°C, HRT-2≤125°C, HRT-3≤150°C.
Models:
Heat resistant conveyor belts fall into three models
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
