1. Specifications: 
Circular vibrating screen: 
1>up/middle vibrator type 
2>95% screening ratio 
3>cement, charcoal, road stone materials 

2. Application of vibrating screen 
Circular Vibrating Screen earns this name by reason of its approximately circular movement. It is of multilayer and high efficiency. The eccentric shaft vibration exciter and partial block help to adjust amplitude. This kind of screen is of long streamline, many specifications and clear screening for different specifications. 

3. Working Principle of vibrating screen 
It uses eccentric block to produce strong exciting force. Crossbeam and the main body of the screen are connected with high strength screw bolts. So they have the features of simple structure and easy maintenance. It adopts tire clutch with capability of flexible connection and stable operation. It adopts the structure of small amplitude, high frequency, large obliquity to make the screen hold the capability of high efficiency, large handling capacity, long life span, low consumption, little noise. 

4. Structure of circular vibrating screen 
It is composed by sieving box, mesh, vibration exciter and damper spring etc. The vibrating screen adopts the vibration exciter with barrel type of eccentric shaft and block to adjust the swing. The vibration exciter is installed on the lateral plate of the sieving box. The motor makes the exciter swing round speedily through tire coupling. The continuous forced circular motions of sieve box were achieved through the powerful centrifugal force. The lateral plate made by the high quality steel plate without any welding point. The lateral plate, beam and the vibration exciter connected by the high strength bolts and ring-grooved lock bolts.
