The conveyor belts are applied for transportation of a wide spectrum of materials with var-
ious technical parameters. An influence of these parameters determines durability as well
as damage level of the conveyor belt. The temperature of transported material is one of the
relevant criteria with a significant impact on the damaging process of the conveyor belt. An
increased degradation of the conveyor belt construction can be caused due to a heat influ-
ence. In this article there are analysed several selected samples of the conveyor belt, which
was used for transport of a roasted ore with the temperature 120
°
C. The small failures
occurred initially during a current operation of this conveyor belt and these failures led
consequently to the development of severe cracks after a longer operational time.
Application of a non-destructive diagnostic method enables to consider a next operation
possibility of the belt as well as to obtain more detailed information about this type of
damaging process
