The vibration locus is a complex space curve. The curve is projected as a circle in the horizontal plane and as an ellipse in the vertical plane. The amplitude can be changed by adjusting the exciting force of the upper and lower rotary weights. And the curve shape of the motion trail of the screen surface can be changed and the motion trail of the materials on the screen surface can be changed by adjusting the space phase angle of the upper and lower heavy hammers. When the vibrating screen is used for screening raw materials which are easy to agglomerate and have large viscosity, meshes are extremely easy to block, and in order to prevent the meshes of the screen from being blocked, the smaller screening machine only needs to be provided with an ultrasonic generator to meet the cleaning requirement of the screen.
