Working principle of circular vibrating screen
The inertial vibrating screen with circular track is called circular vibrating screen for short. This kind of inertia vibrating screen is also called single shaft vibrating screen. Its supporting methods include suspension support and pedestal support. The screen surface is fixed on the screen box. The screen box is suspended or supported by spring. The bearing of the main shaft is installed on the screen box. The main shaft rotates at high speed driven by the pulley. The disc with eccentric weight is installed on the main shaft, and it rotates with the main shaft to produce centrifugal inertia force, which makes the screen box that can vibrate freely produce the vibration of approximate circular track. The distance between the eccentric weight and the bearing center line is the excitation eccentricity.
Main advantages of circular vibrating screen
1. Due to the strong vibration of the screen box, the phenomenon that the materials block the screen holes is reduced, so that the screen has a higher screening efficiency and productivity.
2. The structure is simple and the screen surface is convenient to be removed and replaced.
3. Less electric energy is consumed for screening each ton of materials.
Circular vibrating screen structure: mainly composed of screen box, vibration exciter, suspension (or support) device and motor, etc. The motor drives the main shaft of the exciter to rotate through the V-belt, and the screen box vibrates due to the centrifugal inertia force of the unbalanced weight on the exciter. Different amplitudes can be obtained by changing the eccentric weight of the exciter.
