Vibrating screen design theory

These linear models assume that angular motion of vibrating screen deck is low and and are useful for determining motion under nominal operating conditions because angular displacement is not significant but are not able to predict deck motion during the startup, during shutdown, or under offdesign operating conditions such as the loss of stiffness in supporting positions In practice, there is significant angular
