Working principle of rotary vibrating screen
Rotary vibrating screen is a high-precision fine powder screening machine, which has low noise and high efficiency. It takes 3-5 minutes to change the screen quickly. It has a fully enclosed structure and is suitable for screening and filtering particles, powder, mucus and other materials.
Working principle of rotary vibrating screen:
The three-dimensional rotary vibrating screen uses a vertical motor as the excitation source, and eccentric weights are installed at the upper and lower ends of the motor to transform the rotary motion of the motor into a horizontal, vertical and inclined three-dimensional motion, and then transfer this motion to the screen surface, so that the material can move outward in an expanding involute on the screen surface. Therefore, this series of vibrating screens is called rotary vibrating screens. The rotary vibrating screen has the advantages of long material running track and high screen surface utilization. Adjusting the phase angle of the weights at the upper and lower ends can change the motion track of the material on the screen surface It can carry out fine screening and probability screening of materials.
After the rotary vibrating screen is started, its power device, that is, the eccentric blocks with different phases at the upper and lower ends of the vibrating motor, produces a composite inertia force due to the high-speed placement. The inertia force forces the vibrating body of the screen to make a compound rotation movement, and the screen frame makes a continuous reciprocating motion under the action of the vibration force, which drives the screen surface to vibrate periodically when it enters the ground, so that the material on the screen surface makes a directional and active movement with the screen box, during which, The material smaller than the aperture of the screen surface falls to the lower layer through the screen hole and becomes the material under the screen. The material larger than the aperture of the screen surface is discharged from the discharge port after continuous jumping movement, and finally the screening work is completed. The motion trajectory of the vibrating body of the rotary vibrating screen is a complex three-dimensional curve in space. The projection of this curve on the horizontal plane is a circle, and the projection on the two vertical planes is two identical ellipses. In practice, by adjusting the relative phase of the eccentric blocks at the upper and lower ends of the vibrating motor, the motion trajectory of the material on the screen surface can be changed, so as to achieve different screening purposes.
