Circle vibrating screen do circular movement, is a new type of multilayer number and efficient screen. It is mainly composed of vibrating system of eccentric-block type, meshes, frame body, springs and etc. The eccentric shaft blocks at very high speed and produce vibration by the motor driven through tire couplings. Then the sieve body regularly does repeating and cycle vibration. The materials obtain power and do slung-up movement on inclined sieve mesh. The different size of materials can easily go through the different size meshes, so as to achieve screening purpose.
