Circulra Vibrating Screen Separator For Metal Iron Powder
The rotary vibrating screen is a high-precision fine powder screening machine with low noise and high efficiency. It takes 3-5 minutes to change the screen quickly. The rotary vibrating screen uses a vertical motor as the excitation source. The upper and lower ends of the motor are installed with eccentric weights, which convert the rotary motion of the motor into three-dimensional motion of horizontal, vertical and inclined, and then transmit this motion to the screen surface. . Adjusting the phase angle of the upper and lower ends can change the movement track of the material on the screen surface.
After the rotary vibrating screen is started, its power device is the eccentric blocks of different phases at the upper and lower ends of the vibrating motor. Due to the high-speed placement, a composite inertial force is generated. Under the action of the sieve, it continuously reciprocates, and then drives the screen surface to vibrate periodically, so that the materials on the screen surface move in a directional and active manner with the screen box, during which materials smaller than the screen surface aperture fall to the lower layer through the screen holes , become the under-sieve material, and the material larger than the aperture of the screen surface is discharged from the discharge port after continuous jumping motion, 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 practical application, by adjusting the relative phase of the eccentric blocks at the upper and lower ends of the vibration motor, the movement trajectory of the material on the screen surface can be changed, so as to achieve different screening operations.
