The vibrating screen works by using the reciprocating rotary vibration generated by the excitation of the oscillator. The upper rotating hammer of the oscillator causes the screen surface to produce plane gyration vibration, while the lower rotating heavy hammer produces cone rotation vibration on the screen surface, and the combined effect makes the screen surface produce complex rotation vibration. Its vibration trajectory is a complex spatial curve. The curve is projected as a circle in the horizontal plane and an ellipse in the vertical plane. Adjust the excitation force of the upper and lower rotating hammer to change the amplitude. By adjusting the spatial phase angle of the upper and lower hammers, the curved shape of the trajectory of the sieve surface can be changed and the trajectory of the material on the sieve surface can be changed.
