摘　　要：节能降耗是选粉机改造中的重要技术指标之一。通过构建立磨选粉机的流场模型,采用Fluent软件模拟得出立磨选粉机转笼电动机的做功功率,对导流圈和分级环间距的节能效果进行计算机数值模拟分析。结果表明,当导流圈α角为60°,分级环间距为110mm时,可以有效降低立磨选粉机的单位能耗。Energy saving was an important index in the technical transformation of vertical mill separator.Based on the stablishment of low field model of vertical mill separator,the work power of the motor in vertical mill separator was obtained by Fluent software.The energy saving effect of diversion circle and grading ring spacing were analyzed by numerical simulation.The results showed that the unit energy consumption of vertical mill separator could reduce effectively when the diversion circle angle was 60° and the grading ring pacing size was 110mm.
