Experimental study of the correlation between the conveyor belt structure and the belt puncture resistance

This paper deals with the issue of puncture resistance of rubber-textile conveyor belts. The analysed belts were of identical strengths, but each with a different carcass structure: without an additional anti-puncture layer (breaker layer), with a single anti-puncture layer made of the same material (polyamide), and with an extra anti-puncture layer made of a special material (aramid). In order to achieve a puncture, threshold values of the impact height and the weight of the impacting material were applied. The output of this paper is the determination of a correlation between the conveyor belt structure and the puncture resistance of the belt. The experimental research indicated that the anti-puncture layer (a breaker) is crucial for the elimination of damage to the belt in the form of a puncture.
