Heat Resistant Conveyor Belts
Application:
In General, it is economical to adopt a heat-resistant belt in case the temperature of the materials being transported exceeds 60oC (140oF) Conveyor belting may be damaged by heat, developing cracks or abrasion through stiffening or softening of the cover rubber and separation between plies or between rubber and ply.
Charateristics :
•Excellent heat resistant and abrasion resistant cover rubber compound.
•Recommended to protect conveyor belt from surface cracking and hardening by heat.
•Specially heat-treated and dipped fabric to minimize carcass shrinkage by heat ageing.

Selecting the right heat-resistant belt:
•The surface temperature depends on the material being carried. With large lumps (e.g. sintered ores, coke) which allow air to circulate, the belt surface should be cooler than the lumps.
•In the case of powdery or similar materials, such as cements, carbon black, etc., there is almost no temperature difference between material and belt surface.So when selecting a belt, it’s necessary to know temperature of the material carrying, surface temperature the can bear. More information pls find the following table.
