Abstract

This paper describes an experimental study on self-excited vibration of a vibrating screen. In the vibrating screen excited by an unbalanced rotor, self-excited vibration occurs depending on operating condition. According to experimental results, the frequency of the self-excited vibration is almost the same as natural frequency of the vibrating screen. We investigate the motions of granular material and the effects of acceleration of vibration on outflow of granular material from the vibrating screen. Consequently, it clarified that downward force by mass of the granular material becomes large when a vibrating screen goes down and downward force by mass of them becomes small when the vibrating screen goes up.
