Ball-Tube mill motor vibration AMP Maintenance

Rusty, some of these mills have become huge and the use of hydrostatic and hydrodynamic bearings is not that uncommon. We made some gearsets at my long ago employer that had girth gears of diameters pushing 30 feet. It would be good to confirm their existence however. Dan, I would suspect the readings to be all casing based on the units utilized (mm/sec).
