With one of most advanced design of vibration exciter in the world,using synchronius vibrating way forced by tri-shaft vibrating screen will be easily changed among circular vibration and direct vibration and elliptical vibration.It is suitable for screening materials in large quantity,with several advantages like high screening efficiency,no easy blocking,low installation position and stable movement which is suitable for dry and wet screening.

One more advantage for this machine is that this machine can change tossing materials from the length of large diameter and angle for ellipse,which will meet the demand of this machine.

Amplitude can be changed by changing the quantity of counterweight pins on the counterweight wheel.

Speed can be change in a range by adjusting motor pulley.
