Dynamox’s sensors identified a defect in the bearing of a vibrating screen. On July 26, 2023, an A2 alert was issued on Dynamox’s Web Platform for an asset belonging to one of the world’s largest mining companies in Australia. Due to the location of the asset, it was difficult to get to it and install the sensors.
After the alert was issued, the Waveform Envelope and Spectral Envelope of the asset were analyzed, where it is possible to identify the defect in the bearing related to looseness due to inadequate interference between the bearing and housing and/or shaft.
Using the autocorrelation tool, 2 predominant points of looseness were visualized in the circular form with an offset of 180º.
After analyzing all the data provided by Dynamox’s solution, asset maintenance was carried out. The envelope waterfall shows that the graphs have returned to normal.
