The vibrating screen works by using the reciprocating vibration generated by the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane whirling vibration, while the lower rotating weight causes the screen surface to produce cone-shaped rotary vibration. The combined effect of the vibrator causes the screen surface to produce multi-rotating vibration. Its vibration trajectory is a complicated spatial curve.
The curve is projected as a circle on the horizontal plane, and projected as an ellipse on the vertical plane. The amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. Adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the screen surface movement trajectory and change the movement trajectory of the material on the screen surface.
Vibrating screen is a filterable mechanical separation device used for the solid-phase treatment of mud, consisting of a screen and a vibrator. The thickness of the sieve is expressed by mesh, generally the coarse sieve below 50 mesh, and the fine sieve above 80 mesh. The vibrator is an eccentric wheel that rotates under the drive of a motor to vibrate the screen frame. Due to the vibration of the screen frame, when the mud flows on the screen surface, the coarser solid particles remain on the screen surface and are discharged from one end along the inclined plane. The finer solid particles and the mud liquid flow together through the screen holes to the mud pool. .
