Fatigue failure of deck support beams on a vibrating screen

The design of screens therefore calls for special attention to fatigue detail. An apparently insignificant change in design detail can have a profound effect on the fatigue life of a screen. The catastrophic failure of two deck support beams on a vibrating screen is evidence of …

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.
