Summary of Project

Since they can be operated continuously, belt conveyors are commonly used in mining industry and play an important role in main bulk material haulage systems. Conveyor belt constitutes the most expensive and the most damage-prone part of a belt conveyor, since it has direct contact with mined material. The belt is subjected to a continuous process of wear and tear, but the rate of the process is not constant. As the belt’s operating time increases, the density of core defects increases in a non-linear manner. Predicting the level of the belt’s ultimate limit wear, performing current repairs and disassembling the belt for regeneration at a proper moment are all key issues from the perspective of maximizing belt lie on the conveyor downtime… First research into magnetic inspection of conveyor belt core was performed by Harrison in the 1970s. The method consists in recording the changes of magnetic field in magnetized steel cords of the belt core. The changes of magnetic field are generated by damaged (broken, corroded) or missing cords and by splices of belt sections. Although other research into the application of magnetic method to the diagnostics of conveyor belt core focused on the development of own systems, little attention was paid to the rate of belt wear and ultimate limit belt wear was not identified. Recent studies have confirmed the possibility of detecting even the smallest damage of steel cords in conveyor belt. Currently used postprocessing methods also allow to denoise low amplitude signals. By that means it is possible to recover information about the least damage when the information is in the signal at the noise level. The project centres on creating a novel and inexpensive method for real time conveyor belt steel cord and splice condition monitoring.
