The motion of a Low-Head Vibrating Screen is considered to be a linear simple oscillation, if the reaction force which is equal to the weight of screen always acts on each fixed end of supporting ropes. But if the centers of gravity of unbalanced weights in vibrator have asymmetric arrangements, it becomes an elliptical orbit.
Taking the effects of supporting springs into consideration, the author developed theoretical equations (eq. 11 & 12) governing this motion analytically. Although the vibration varies with the velocity, it can be assumed as a linear vibration at the suitable velocity, and the orbit indicated by the author's equations is almost coincident with that of. a Low-Head Screen used in general practices.
In designing and manufacturing a Low-Head Screen, it is recommended to use a model machine, by which the vibration test is to be conducted applying the law of similarity the author proposed.
