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 screens is established.

2019-6-28 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.

Screening is an important part of processing and is used to separate material according to its size. Material is typically fed to a single-, double- or triple-deck screen to make the required sizes. Screens can be considered the cashbox of the operation, because while crushers make the gradation, screens make the specification. Material must go through or over a specified size to end up in the ...
