The large-scale development of the vibrating screen mainly aims to increase the screening area of the vibrating screen, the vibration intensity of a vibration exciter and prolong the service life of a bearing of the vibration exciter. Most of the vibration exciters of the existing circular vibrating screen are of a single-shaft or double-shaft structure, so that the screening area and the vibration weight of the circular vibrating screen are restricted by the service life of a bearing of the vibration exciters, the circular vibrating screen cannot meet the requirement of large-scale circular vibrating screen, vibration parameters cannot be improved, and the increase of processing capacity is influenced. Therefore, it is not an effective method to simply increase the vibration parameters to adapt to the large-scale development of the vibrating screen. The problems of poor integral rigidity of the screen frame, unbalanced stress on each point of the screen frame during vibration, short service life of the screen machine, low reliability and the like caused by large-scale vibrating screen can be fundamentally solved by considering the structure and the whole.
