Vibrating Sieve Diagnosis and Noise Control

Analysis of the smartphone video sound-track shot outside the complainant’s house and close to potential noise sources on an industrial site allowed us to pin-down the source of the low frequency tone that had been the cause of long term complaints. Based on the mechanical information provided, we proved that the culprit was not the fan previously diagnosed locally, but a vibratory sieve. We then provided a virtually cost-free modification (mechanical disconnection from the building steelwork) to solve the problem. The whole process cost a few hundred pounds and only took a few days.

We have also generated a comprehensive technical note on all aspects of vibrating feeder, hopper, conveyor and screen noise...
