The working principle:
use upright motor as the source of vibration,equippedeccentricity hammeronthebothsidesofthetopandthebottom,changecircumrotatetolevel,uprightandslopemovement, then pass these three movement to the surface of the griddle.Adjust the phasic angleonthebothsides of the top and bottom to change the movement orbits of the surface griddle.
This circular vibrating screen from ?400mm��?2500mm can be designed and moves in a circular motion. They can be installed four layers of sifters at most. Their electromotor can vibrate steadily and produce great vibration strength. The flexible net frames are easy to stretch completely and replace in a very short time so that their efficiency is raised greatly. A multi-layer and high efficiency vibrating screen.

its advantages include as follow :
(1)a stable structure, high efficiency,
(2)low noise pollution,
(3) handy maintenance
(4)safe operation. Commonly ground can be used
(5) Easily to replace the net, simple operation and convenience washing.just need 10 minutes.
(6) The highest layers of the griddle are about 4 layers. But 3 lagers are suggested.
