This series of vibrating screen is also referred to as circular vibrating screen because its movement is approximate to be a circular motion, and it is an efficient new vibrating screen with several layers. The machine uses an eccentric vibration exciter and tire couplings to improve the service life of equipment; the equipped spring damping device can effectively reduce the impact on the foundation and lower the vibration noise.

Working Principle of small circular vibrating screen:
When  circular vibrating screen on operation , first the materials will feed on  circular vibrating screen mesh , and the materials will separated uniformly on screen mesh plates . The rolling bearing of  circular vibrating screen will stressed by highly mostly shock-type loads . And more , the  circular vibrating screen bearing ,while rotating about their own axis ,going a way of circular ,elliptical or linear vibrating motion . This results in high radial accelerations which additionally stress the bearings , and especially the cages considerably. The operating speeds are usually in a very high condition . As a result, the bearing temperatures are up to 20 to 30 degrees Kelvin higher than in normal applications. In addition, considerable misalignments between the bearing locations and considerable shaft deflections have to be accommodated.

Features of small circular vibrating screen:

1 Used the eccentric block as excitation force ,strong excitation .
2 High strength bolt connection between sieve beam and screen box ,no welding .
3 Simple structure ,easy maintenance .
4 Use tyre couplings ,flexible connection ,stable operation .
5 High screening efficiency ,large handling capacity ,long life span
