| Abstract: |
| The four edged asynchronous shear rotor of electromagnetic dynamic mixer was designed，and the three-dimensional mathematical model of the rotor under the condition of electromagnetic vibration was established.The flow field of the rotor was dynamically simulated and analyzed by using professional fluid software Polyflow，including pressure field，velocity field，shear rate distribution，viscosity distribution，mixing index distribution and concentration field.The results showed that，under the condition of electromagnetic vibration，the time of maximum pressure，maximum velocity，maximum shear rate and maximum mass concentration in the rotor flow field was shortened，the viscosity at the convex edge of the rotor was very small，the viscosity at the smooth part of the rotor was large，and the mixing index was small，so that the rubber could be mixed quickly，the mixing efficiency was improved，and the mixing energy consumption was reduced. |
