Exciter is as source of round vibration screen , generally composed by part vibrator, screen box, vibration isolation devices, gear and other components. Sieve shaker with a rectangular surface mounted on the sieve box. Screen box and the screen surface under the action of the vibrator, vibration round, oval or linear trajectory. Due to the surface so that the shaker screen surface ... round shaker vibration source for exciter, generally by part vibrator, screen box, vibration isolation devices, gear and other components. Sieve shaker with a rectangular surface mounted on the sieve box. Screen box and the screen surface under the action of the vibrator, vibration round, oval or linear trajectory. Since the surface of the material shaker screen surface layer of loose and toss away from the screen surface, so that fine particles can fall through the material layer and is discharged through the sieve, and stuck in the mesh of particle vibration out, in addition to generating sieve outside the sub role, and the forward movement of the material.
Vibrating Screen with a circular trajectory is circular vibrating screen, referred to as circular vibrating screen. This is also called single-axis inertial vibration sieve shaker circular trajectory inertia shaker can be used for various screening operations. Because of the circular vibrating screen surface of the track, so that the material is constantly flipping the screen surface and loose, so round vibrating screen has the following characteristics:
1. Fine grade have the opportunity to move to the lower material layer, and discharged through the sieve;
2. Card of the material in the sieve can jump out and prevent clogged sieve;
3. High screening efficiency; 
4. You can change the screen surface angle, thus changing the velocity of material along the screen surface to improve the handling capacity sieve; 
5. For difficult materials can make the counter-spindle turning, so that the direction of movement in the opposite direction of vibration with the materials, the material along the screen surface movement speed is reduced (in the sieve surface inclination and spindle speed the same situation), to improve screening efficiency.
