What measures are taken against the vibrating screen to avoid resonance?
The curve is projected on the horizontal surface into a circle, and the projection on the vertical surface is an ellipse. Adjusting the exciting force of the upper and lower rotating weights can change the amplitude. While adjusting the spatial phase angle of the upper and lower heavy weights, the curve shape of the screen surface movement track can be changed, and the movement track of the material on the screen surface can be changed.
The upper rotating heavy hammer of the vibrator causes the screen surface to produce a plane whirling vibration, while the lower rotating heavy hammer causes the screen surface to have a conical rotary vibration, and the combined action of the rotating heavy hammer causes the screen surface to generate a complex rotary vibration. The vibration trajectory is a complex space curve.
The vibrating screen is operated by the reciprocating rotary vibration generated by the vibrator excitation.
