Abstract
Conveyor belts with woven plastic belts, aimed for general applications, are very economical transporting means for longer distances. During the operation, the conveyor belts are subjected to various mechanical loadings. The consequences of those loadings are increased stretching of the belt and change of its tensile strength, which negatively affect the proper functioning of the transporter. To avoid the irregularities in the conveyor belt's operation, the tensile properties of the two plastic woven belts were tested (maximal force, maximal extension, breaking force and extension at break). In that way the conditions of the two belts were established. Based on performed experiments the belt that is more suitable for application in the transporter was defined.
Highlights
Modern exploitation technology has determined the importance and role of the continuous transport, especially of the conveyor belts, as their main representatives
The best method to determine the state of the belt is to control its stretching and the tensile strength
Two experiments were performed on samples from the two types of woven plastic belts, 22BY and 31BY
Summary
Modern exploitation technology has determined the importance and role of the continuous transport, especially of the conveyor belts, as their main representatives. The belt conveyors can have the load carrying capacity up to 30000 t/h and can be used for transporting the materials along the large length of conveying paths of up to 3-4 km They are of relatively simple design, maintained and highly reliable in operation. The aim was to determine the conditions that caused this type of damages - the height of the material pieces impact and their weight They used the nondestructive method of the computer metro-tomography to study the changes in the construction of the conveyor belt. The best method to determine the state of the belt is to control its stretching (extension) and the tensile strength This would guarantee that the conveyor belt is fully operational to properly execute the task in the manufacturing process. The objective of this paper was to establish the state of the two plastic woven belts of the transporter system from the aspect of the mechanical properties reliability and to determine which one is more suitable for application in the particular conveyor belt transporter
