Vibrating Screens ZHENYING. Multi frequency screen. Description The multi frequency screen makes the screen machine with two or more than two vibration sources to produce different vibration frequency, so that the screen machine produces different frequency and amplitude, and makes the movement phase angle between the materials changeable in the screening process. Get Price Circle .

By analyzing the rigid-body modes of the vibrating screen, the natural frequencies, mode shapes and other dynamic parameters are obtained. The results show that: the natural frequencies of three-body vibrating screen modes are more concentrated; the damping bearing is the weak link of the vibrating screen.

The natural frequency, as the name implies, is the frequency at which the system resonates. In the example of the mass and beam, the natural frequency is determined by two factors: the amount of mass, and the stiffness of the beam, which acts as a spring. A lower mass and/or a stiffer beam increase the natural frequency; a higher mass and/or a softer beam lower the natural frequency.

Vibration is the key. Which is why it is very important to know the natural frequency of your product. Vibration is bound to happen if there is a vibrating element (such as a motor or actuator). A safe design would then need to have a natural frequency which is way way different from the frequency of the vibrating element.

To allow the smooth and energy efficient functioning of the screen, frequency optimization is inevitable. In this paper, the optimal vibrational parameters were determined partly by using analytical methods. The analytical model deals only with the movement of one spherical grain in a non-inertial reference frame. By using the analytical model, an optimal frequency range for screening was ...
