High-vibration incidents at the Proserpine, Victoria and Plane Creek shredders – actions and response planning* [Full subscriber]

Abstract         During the 2018 crushing season, Victoria Mill’s B side Shredder developed reoccurring high levels of vibration with variability in the phase angle following the processing of low-quality cane. Over a course of weeks, the vibration levels trended upward until reaching unacceptable levels (>10 mm/s).  Vibration analysis trends indicated an out-of-balance phase angle shift.  This followed evidence of a phase-angle shift at the Proserpine Mill when the disc pack was found to be loose.  With 10 weeks until the end of crush, attempts were made to reduce the vibrations at Victoria Mill to acceptable levels and manage the operational capacity…
