Spring Failure Analysis of Mining Vibrating Screens:
Spring failure is one of the critical causes of the structural damage and low screening efficiency of mining vibrating screens. Therefore, spring failure diagnosis is necessary to prompt maintenance for the safety and reliability of mining vibrating screens. In this paper, a spring failure diagnosis approach is developed. A finite element model of mining vibrating The structure of a real vibrating screen is particularly complicated and mainly comprises a screen box, screen mesh, and vibration exciters.
