Heat Resistance Conveyor Belt

Heat resistance conveyor belt is made of multi-layer rubber cotton canvas (polyester cotton) or polyester canvas covered with high temperature or heat resistant rubber; Vulcanized by high temperature bonding, suitable for conveying hot coke, cement, slag and hot castings below 175℃. Mainly used in metallurgy, construction and other industries, conveying sinter, coke, cement clinker and other high-temperature materials, the material temperature does not exceed 800℃, belt surface temperature does not exceed 220℃ conditions for use.

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;
