Fatigue failure analysis of vibrating screen spring by

Vibrating screens are often used in the mining industry to separate mineral particles by size. In many designs, spring arrays are used to provide the system with the necessary stiffness for screens to vibrate in a controlled manner. Naturally, these springs are subjected to varying loading cycles, which can cause their premature fatigue failure.

Springs of vibrating screens are prone to fatigue induced failure because they operate in a heavy duty environment, with abrasive dust and under heavy cyclic loads. If a spring breaks, the stiffness at supporting positions changes, and therefore the amplitude of motion and the static and dynamic angular inclination of deck motion also change.

Vibratory Screens | McLanahan

Vibratory Screens can be subdivided into Inclined and Horizontal style screens. Today's screens come in widths from 4'12' wide and from 8'32' long. Screens are normally sized so that the length is 2.5 times the width. The width of a screen will determine the maximum carrying capacity of the screen deck, while the length of the screen will determine the overall efficiency of the deck.
