Introduction: 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. Characteristics and advantages: 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, and little noise. Working principle: Motor makes vibration generator eccentric block high speed rotate by triangular belt, eccentric block generates large centrifugal force when revolving, circular motion is made by revolving straining box, the material on the oblique screen surface dose constantly throwing motion under the impulse given by straining box, the standard size of material goes through the screen while material shaking on the surface of the screen, then the whole process is completed.
