High Vibration Ball Mill Duel Pinion Drive
A vibration survey was carried on this Ball Mill with a duel pinion drive. The vibration is high in all planes on both sides of the Mill or both pinion drives. The measurements were similar in velocity on the motor , gearbox and both pinion bearings. The recommendations for repairs was close to exactly the same for both drives.
