双转子连续混炼机混合过程物理模型的建立

Modeling of mixing process in two rotor continuous mixer

建立了双转子连续混炼机混合过程的物理模型，分析了影响其混炼段融体输送过程和混合过程的主要因素，并提出：转子混炼段融体输送量与转子螺棱几何形状、物料粘度、混炼段融体压降等有关；转子对物料的混合过程与转子组合（螺棱交汇区长度）、转子螺棱几何形状、转子转速等因素有关。

A model for the conveying of molten material in the mixing section of a rotor of two rotor continuous mixer was proposed.Factors,which had influence over the conveying and mixing of molten material, were discussed.It was pointed out that the conveying of molten material in the mixing section of rotor was related to the appearance of rotor wings,viscosity of molten material and the differential pressure in the mixing section of rotor,and that the mixing of molten material was related to the length of apex region,the appearance of rotor wings and rotor speed.
