Heat Resistant and High Temperature Resistant Belt

Heat-Resistant-&-High-Temperature-Resistant-Belt Heat-Resistant and High-Temperature-Resistant-Belt









The carcass is made from high modulus, low shrink Polyester fabric, Cotton fabric, Cotton or Terylene/Cotton fabric. Choosing heat resistant or high temperature resistant rubber material as the cover rubber, the belt is manufactured by forming and vulcanizing.


Suitable for using in the field of metallurgy industry and construction where there is the need to conveyor hot materials such as sinter, coke, cement clinker as well as numerous other industries that need High Temperature Resistant Conveyor Belting.


Heat Resistant

T1: Suitable for using at temperature from 60 to 125 deg C Continuous rated, and temperature of 150 deg C intermittently

T2:  Suitable for using at temperature from 125 to 150 deg C Continuous rated, and temperature of 180 deg C intermittently

High Temperature Resistant

T3: Suitable for using at temperatures up to 180 deg C continuous rated, and temperature of 230 deg C intermittently.

How to Get Proper Belt

Following factors need to be considered to get proper belt
·Materials temperature, shape, adhesive parameter, etc.
·When conveying big size materials such as sinter, coke etc with high temperature around 150 degree C,also with small contact area with the belt, the belt surface temperature will be between 60-80 degree C.
·It will be small difference in temperature between belt surface and material when conveying low adhesion materials such as cement, flour etc.
·Belt surface temperature affects directly belt life time, so that full investigation on belt surface temperature need to be done before choosing the proper grade for the heat and high temperature resistant belt.

Maintenance and Inspection 
·Keep regularly inspecting and consistent measuring to be sure belt surface temperature at reasonable level.
·We strongly recommend that heat resistant belts to be cooled on the return course by water spray or other suitable cooling methods. Always try to evenly distribute materials across the width of the belt so as to reduce the heat concentration in the center of the belt.
·Oil contained in cooling water or in materials will be very harmful to the life of belt, even worse than heat itself, thus the oil must be prevented. The heat materials should be unloaded once belt stops working.
·Hot vulcanization joint is recommended.
