The three-shaft vibrator is the heart of the vibrating equipment. The three sets of eccentric blocks it carries, according to the designed phase angle, through a synchronizer transmission mechanism, make the resultant exciting force of the three sets of eccentric blocks form an elliptical motion trajectory, which is accurate and reliable, enabling full screening of materials.
