Electrostatic stalk-sorting shaker is the one of key equipment of CTC red tea production. For confirming the stress distribution of shaker and ensuring the strength of the shaker body

the finite element model for strength calculating of the shaker body is built. The natural frequencies and the model shapes of the shaker are calculated. Analysis results indicate that the natural frequency of overall shaker is higher and far away from normal working frequency

that the rigidity of shaker is good.
