Heat resistant conveyor belt

Products Specification:

Product characteristics:

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 Chloro-butyl 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 carcass of this product has very high adhesion after the special treatment of coating and shaping. Under normal working temperature of below 180℃, the belt is low in elongation, excellent in anti-abrasion, and can bear 250℃ high temperature for a short time. The belt is suitable for use in cement, metallurgical and steel industry.

The heat resistant conveyor belt include four types.
Type I: it is able to resist the test temperature of no more than 100 oC,
             the max. short-time operating temperature is 150 oC, the symbol is T1.
Type II: it is able to resist the test temperature of no more than 125 oC,
              the max. short-time operating temperature is 170 oC, the symbol is T2.
Type III: it is able to resist the test temperature of no more than 150 oC, 
               the max. short-time operating temperature is 200 oC, the symbol is T3.
Type IV: it is able to resist the test temperature of no more than 175 oC,
               the max. short-time operating temperature is 230 oC, the symbol is T4.

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.
