【摘要】 对硅胶颗粒在圆筒型混合器中的混合运动和机理进行了实验研究,分析了填充率、转速等因素对混合过程的影响。研究结果表明:混合过程中颗粒运动的流线不断被拉伸和弯曲,是形成颗粒扩散运动的重要机制;填充率和转速对颗粒的混合运动有明显影响,当填充率不变时,混合效果随混合器转速的提高而提高(接近离心状态之前);当转速不变时,混合效果随填充率增大(不超过70％)而提高。当填充率和转速提高时,颗粒的运动模式由rolling模式向cascading模式发展。更多还原

【Abstract】 The experiment has carried on rotating drum blender to explore the mixing motion characteristics and mixing mechanism, the influence of rotation speed and vessel fill percentage on mixing efficiency are analyzed. The results indicate that the granular mixing motion is impacted by the vessel fill percentage and rotation speed. The mixing efficiency is enhanced as the rotating speed and vessel fill percentage increase.更多还原
