The circular vibrating screen is mainly composed of screen box, vibration exciter, suspension or support device and motor. Once operated, the motor drives the main shaft of the exciter to rotate through the V-belt, and the screen box vibrates due to the centrifugal inertia force of the unbalanced weight on the exciter. It can obtain different amplitudes by changing the eccentric axis of the exciter. Various products are sieved out through multiple layers of screens, and then discharged from the discharge outlet.
