Shaker is the use of a reciprocating screw-type vibration transducer excitation arising from the work. Oscillator on a rotary hammer so that the screen surface to produce flat whirling vibration, while the lower rotating weight makes the screen surface to produce cone rotary vibration, the effect of their combined effect makes the screen surface to generate complex spin-type vibration. Vibration locus is a complex space curves. The curve is a circular projection in the horizontal plane, and in the vertical plane of projection is an ellipse. The regulator, under the rotating weight of the exciting force, Tianjin shaker, you can change the amplitude. And adjust the upper and lower hammer spatial phase angle, you can change the shape of the curve trajectory of the screen surface and change the trajectory of the screen surface materials. Action shaker vibration isolation devices are: ① system natural frequency of the spring stiffness and function of the quality of the vibration, shaker works, determine when the screen quality, high shaker, the natural frequency of vibration depends on the stiffness of the spring. Therefore, the elastic spring rate determines the stability of the system working status and screening machines work. ② spring stiffness, pass basic dynamic load also great. Therefore, an appropriate choice of the stiffness of the spring, can be reduced to pass basic dynamic load.
