Online condition monitoring on rotary calciner
This materials processing plant replaced its previous vibration monitoring system on the low-speed calciner drum with the online system Intellinova Compact after a test installation involving SPM HD measurements had proven successful.
During the test run in the fall of 2013, the system immediately and very clearly indicated an outer race-bearing defect in one of the support wheel bearings. Approximately three months later, the bearing was replaced, and the outer race damage confirmed. Based on these test measuring results, a permanent Intellinova online system was installed in the first half of 2014.In 2017, new test measurements were conducted using the DuoTech accelerometer, which enables combining the SPM HD and HD ENV condition monitoring technologies in a single transducer. In conjunction with these tests, the plant maintenance team decided to also try the HD ENV vibration enveloping technology. Further bearing damages detected during this second round of tests confirmed the capability of the HD condition monitoring technologies and DuoTech accelerometers to detect early-stage bearing damages on this low-RPM application, and to track the damage development process over time.
