Abract:The flow field of de-airing pug spiral reamer was analyzed by the FEM software ANSYS,the press field,velocity field and temperature field of ceramic paste extruding process in the twin-screw extruder were gained .It provides some theory reference for the research of ceramic paste twin-screw extruder, and it provides important guidance for improving extruding efficiency and quality of ceramic paste.

Key words:ceramic paste twin-screw extruder; ceramic; FEM analysis
