Universal Joints Help Reduce Mill Vibration

They recommended that all the gear spindles be converted to universal joints, which would reduce surface damaging vibration almost completely, while allowing the mill to run at faster speeds. After testing competitive models, the mill selected Americardan Model U3440 universal joints. The mill was then able to run at record-setting production levels with reduced vibration and minimal related

Cement Industry Raw Mill Vibration Monitoring AMP

Component deterioration can include roll and table surfaces, roll and table bearings, roll load springs, and gearbox bearings and gears. Overall vibration levels can indicate a change in mill condition, and vibration analysis can identify deteriorating components. In summary, low vibration levels and machine reliability can be maintained by:
