翻转卸料双轴桨叶饲料混合机工作性能试验研究

Experimental study on mixing performance of the twin-shaft paddle rotating mixer

摘要: 该文介绍了作者设计并研制的新型翻转式双轴桨叶混合机，阐述了其工作原理。为了提高双轴桨叶混合机的混合性能，采用二次回归正交旋转组合试验，对设计样机进行混合均匀度及机内残留率的试验研究，得出了其工作参数的合理组合：混合时间为180 s，充满系数为0.75，桨叶轴转速为56 r/min；机内残留量极小(约为0.015%)，满足其作为配合饲料生产，尤其是预混合饲料生产的工艺要求，也为进一步改进设计提供了依据。

Abstract: The working principle of the twin-shaft paddle rotating mixer was discussed in this paper. And the "three-factor quadratic regression orthogonal rotary method" was adopted to study mixing performance of the mixer，after the machine had been designed and trial-produced. It was showed that the optimum technological parameters for mixing time, block coefficient and rotary speed of the paddle shaft were 180 s, 0.75 and 56 r/min, respectively. At the same time, the remains in the bin was little (0.015%). The effect could meet premix feed technological demands, and the results provide reference for improving design.
