Screener troubleshooting: Diagnosing and solving screen ...

and breaks from the wire's vibration-induced up-and-down movement. Another common cause of wire fatigue is abrasion, which occurs particularly when you're screen-ing heavy or abrasive materials such as sand and other minerals. The particles' constant movement across the screen abrades the wire, reducing its diameter and making it weaker.

Structural Vibration as a Noise Source on Vibrating Screens

deflection shape (ODS) analysis was used to examine the screen behavior under actual operating conditions. This information is helpful in determining how to modify the screen body to reduce the noise radiated by the screen below 1 kHz. The analysis showed modal vibration patterns on the sides and feed box were the main contributors to noise.
