Abstract

本文针对四个不同容积（1.884升至30.144升）的旋转滚筒中的二元颗粒径向偏析现象进行研究，重点关注了相同弗劳德数下不同尺寸滚筒中颗粒偏析的相似性，以及不同弗劳德数下的差异。研究结果表明：在恒定弗劳德数条件下，随着滚筒尺寸的增大，偏析性能逐渐恶化，但颗粒流型和最终偏析状态相似。此外，随着滚筒的放大，颗粒平均速度逐渐提高，滚筒功率消耗也随之增加。提出了放大比与弗劳德数的相关函数，可用于偏析速率的预测。在不同弗劳德数条件下，同一滚筒的偏析速率随着弗劳德数的增大而增大，通过提高滚筒转速可以有效抑制偏析。此外，研究还发现，无论弗劳德数为多大，尺寸较大的滚筒在不同转速下的偏析速率都具有很好的一致性。
