Analysis of the Melt Conveying Zone in Counter-rotating Twin Screw Extruder

There is three-dimensional flowfield  of the melt conveying zone in an intermeshing counter-rotating twin screw extruder. Nowadays, the research about twin screw extrusive process main focus on the step of fuse-element output. This is because the output characteristics of materiel in this section  clearly affect the performance characteristics of twin screw extruder and the solution of molten ingot flow process can take research achievements of hydrodynamics as reference. Rotational direction of screw must maintain a certain relationship with the rotational direction of thread in order to make sure that the materials can transfor from the charging hole to the head of extruder.
