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 suppo-t beams on a vibrating screen is evidence of the above statement and the subject of this paper.
