After some mixed methods in polymer processing are summarized, the new equipment is introduced which is called vane plasticizing extruder with elongational flow field. Then the unit of vane geometry is analyzed, and the analysis method of vane extruder conveying state is put forward by using the lattice Boltzmann method. On this base, physical model and mathematical model are established. Calculation of velocity distribution and quantitative description of the elongational deformation rate shows there has elongational rheological in the vane plasticizing extruder. Periodic extensional flow field has very good mixing effect in polymer processing.
