摘要
基于 40· 5 3型双进双出磨煤机实际工况条件 ,对双进双出磨煤机内流场进行了数值模拟。通过分析磨煤机入口风速和磨煤机填充率对内部流场的影响规律 ,获得了一些有利于磨煤机的研磨、干燥、气力选粉和输粉过程的相关条件。图 5表 2参
A serie of cold model tests had been carried out on double charge discharge coal ball mill. Operating characteristic of the gas solid two phase flow in cylinder coal ball mill had been obtained. It was further cleared that different flow fields influence drying coal, grinding coal and conveying pulverized coal in the ball mill. The results of cold model test are useful for design and control of double charge discharge coal ball mill. Figs 5, tebles 2 and refs 7.
