Continuously Monitoring a Critical Centrifuge Bearing with Ultrasound and Vibration at Greenfield Ethanol

Hannah Grundie2026-07-07T18:08:17+00:00 A centrifuge uses centrifugal forces, generated at high RPMs to separate solids and liquids. At Greenfield Ethanol, they use centrifuges in their manufacturing processes. They are critical to their operations.  This centrifuge in question rotates at 5250RPM, and it has a suspected bad bearing. The following...
