Description
Vibrating screen is to utilize the reciprocating rotary vibration produced by the vibrator excitation and work. The upper rotating weight of the vibrator makes the screen surface produce plane rotary vibration, while the lower rotating weight makes the screen surface produce cone rotary vibration, and the effect of its joint action makes the screen surface produce compound rotary vibration. The vibration trajectory is a complex space curve. The curve is projected as a circle in the horizontal plane, and the projection in the vertical plane is an ellipse. Adjusting the excitation force of the upper and lower rotating hammers can change the amplitude. Adjusting the spatial phase angle of the upper and lower hammers can change the shape of the curve of the screen surface trajectory and change the trajectory of the material on the screen surface.
