### Vibrating Screen Working Principle

When the smaller rock has to be classified a vibrating screen will be used. The simplest Vibrating Screen Working Principle can be explained using the single deck screen and put it onto an inclined frame. The frame is mounted on springs. The vibration is generated from an unbalanced flywheel.

The reason for this is that the system that is vibrating includes the spring itself. However, the entire spring does not vibrate with the same amplitude as the load and therefore it is reasonable to assume that the effective load is the mass hung from the end of the spring plus some fraction of the mass of the spring. The fraction used was 1/3 since similar …
