The enlargement of structure of vibrating screen will lead to the increase of vibration mass and exciting force. Dynamic load on the vibrating screen is also increased which will lead to a greater deformation, tear of the side plate, fracture of the crossbeam, and thus affects the service life of the vibrating screen seriously [1-3] .

Taking into account that vibrating screens usually work at high frequencies, a stress-based approach was used to predict the life of the springs. Goodman theory for mean stress correction was used together with the von Mises equivalent stress. Finally, the highest cycle number in the S-N curve defined infinite life (10 9 cycles). 4 RESULTS

What are vibrating screens and which are its main applications for use. Also called simply screens, a vibrating screen is formed by a vibrant chassis that supports in its interior one or several surfaces or elements of screening. The screens serve to classify the different particles by size, starting from a bulk product in a continuous process.

Operational Theory. The Prater Vibratory Screener utilizes a vibrating deck that is attached to one or more screening elements. Each of the screens is used to segregate and capture a specific size fraction of the aggregate particle mixture. Screening efficiency is much greater when a vibratory enhancement is added to the sizing process.
