Title:
EXTRUDER SCREW STRUCTURE WITH INDEPENDENTLY STAGED TEMPERATURE CONTROLLING DUAL MIXING ZONES
Document Type and Number:
WIPO Patent Application WO/2010/133084
Kind Code:
A1
Abstract:
An extruder screw structure with independently staged temperature controlling dual mixing zones, includes the first screw group and the second screw group which are respectively located in the first mixing chamber (23a) enclosed by the first inner chamber shell (22a) and the second mixing chamber (23b) enclosed by the second inner chamber shell (22b). Each screw group includes a main screw and an auxiliary screw engaged with each other. The end of said first main screw (41a) unengaged with the first auxiliary screw (42a) is engaged with the end of said second main screw (41b) unengaged with the second auxiliary screw (42b), and the engaged section is located in an end mixing chamber (23'). Said extruder screw structure can mix material independently in each mixing zone, and finally mix the material from the two mixing zones, therefore can carry out better mixing for various materials which need heating at high temperature or low temperature.
