Improvement of Mixing Mechanism for Twin-shaft Mixer

According to the structural characteristics of the twin-shaft mixer,this paper analyzed the defect of mixing inefficient zone existing in the mixing mechanism.An improvement measure of double-row blades was put forward.Based on the prototype,test research was conducted.The results indicate that the new mixing mechanism can improve mixing performance of the inefficient zone.The achievement can also be applied to other types of forced mixer with cylindrical mixing trough.
