Identification of damage development in the core of steel cord belts with the diagnostic system

Abstract Belt conveyors are used for transporting bulk materials over distances. The core of the belt, by transferring longitudinal stresses and ensuring proper frictional coupling enables belt movement transportation on its surface. As cover edges used, becomes abraded, is subject to fatigue. result development cracks in rubber covers across which leads damage not only along cables (the natural direction water migration corrosion) but also transverse axis. Conducting a series scans St-type operating one underground copper ore mines Poland allowed identifying number failures as well their size changes time. These data were turn determine measures defining condition such density defects per 1 m belt), area belt) change average single defect By determining regression these time rate both directions (along axis it was possible forecast future states evaluate costs different replacement strategies economic rationalization decision replace them. This research has become owing DiagBelt system two-dimensional imaging steel-cord belts with resolution sufficiently high allow tracking defects.
