Fatigue failure analysis of vibrating screen spring byAuthor Rosendo Franco, Pedro A. Flores, Angel A. C. Peinado

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. This behavior has been studied by means of finite element analysis and compared with data
