Abstract:

This article summarized the similarity amplification criteria proposed for screw extruders both domestically and internationally in recent years, and the commonly used amplification coefficients and applicable ranges were compared and analyzed. Meanwhile, the practical applications of similarity amplification theory in optimizing the structural parameters and processed conditions of screw extruders were introduced. Finally, the further exploration and optimization of similarity amplification theory for screw extruders were pointed out. This paper provided an effective theoretical support for the sustainable development of screw extruder industry.

Key words: similarity amplification theory, screw extruder, dimensionless group, scale?up, application
