Vibrating Screen

Vibrating screen is mainly composed of screen box, vibration exciter, suspension (or support) device and electric motor. The motor drives the main shaft of the vibration exciter to rotate through the triangular belt. Due to the centrifugal inertia force of unbalanced weight on the vibration exciter, the screen box is vibrated. Different amplitudes can be obtained by changing the eccentric weight of the exciter.
