It isnot only demand higher productivity . better screening efficiency or effectiveness dehydration . low power consumption .but also with simple structure . easy to manufacture . installation and maintenance convenient mechanical properties. As roller sieve . sieve cylinder of the poor .by the use of restrictions have been gradually effect of good . simple structure and easy maintenance replaced by the shaker. In this paper . systematically expounded the two-synchronous motor shaker since the application status and trends on the design of highly efficient dual-synchronous motor shaker since the necessity of the dual-motor while simultaneously shaker since the principle of the analysis . calculate the shaker The parameters . parameters of kinematics . design and calculation of the axis of the exciter . the parameters and polarization block structure . damping device . the screen box design and coupling the selection.
