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.
Working Principle
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
convert the rotary motion of the motor into horizontal, vertical, and inclined three-
dimensional motion, and then transmit this motion to the The screen surface makes
the material expand involute movement on the screen surface, so this series of
vibrating screens are called rotary vibrating screens. Rotary vibrating screen has the
advantages of long trajectory of material running and high utilization rate of screen
surface. Adjusting the phase angle of the upper and lower ends of the weights can
change the movement trajectory of the material on the screen surface. It can perform
fine screening and probability screening of materials. grade.
After the rotary vibrating screen is started, its power device is the eccentric blocks at
the upper and lower ends of the vibrating motor with different phases. 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 material under
the sieve, and the material larger than the aperture of the sieve surface is discharged
from the discharge port after continuous jumping motion to complete the screening
work. 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.
