Crusher

The shaft of the crusher was systematically changed after operating 500 hours without knowing if the component needed to be changed. This short preventive maintenance interval is due to the fact that the machine crushes a very abrasive material.Thanks to vibration, acoustic emission and temperature data, the wear models of the shaft were created and the Remaining Useful Life (RUL) of the shaft was calculated in order to optimize preventive replacement time which is most of the time greater than 500 hours (715 Hours on average →+43 % of production time).
