Heat-resistant conveyor belt is also one of the commonly used conveyor belt types. The heat-resistant conveyor belt is mainly used in metallurgy, construction and other industries to transport high-temperature materials such as sinter, coke and cement clinker. The temperature of the material does not exceed 800 °C, and the surface temperature is not Use at temperatures above 220 °C.
How to identify the quality of heat-resistant conveyor belt, ZT BELTING to tell you a few suggestions.
Choosing the right tape depends not only on the thermal strain but also on the chemical mechanical stress;
The life of the heat-resistant conveyor belt is greatly affected by the surface temperature of the tape, and it affects the cover rubber and the core delamination. Therefore, when selecting the tape, it is extremely important to consider the surface temperature of the tape, as well as the ambient temperature, when the tape returns. Can it be fully cooled; belt speed and center distance are all worth noting;
The temperature of the material to be conveyed and the surface temperature of the belt vary according to the composition, properties, surface structure and particle size of the material, such as when the temperature of the bulk material is 150 ° C (coke or sintered ore) and the contact area with the belt is small, The surface temperature of the tape can be maintained at 60 to 80 °C. However, when conveying cement powder, the difference between the temperature of the material and the surface temperature of the belt is small;
The thicker cover rubber is an important condition to ensure a long life of the belt. We recommend the thickness of the cover rubber of the fabric core heat-resistant belt: the upper cover is 6-8 mm, and the lower cover is 2-4 mm.
