【摘要】 运用正交试验方法，探求了ＮＨＦ－Ⅱ型分级机的最佳操作参数，并对分级粒径及部分分级效率与影响因素的关系进行了回归分析，该研究对分级机的工业化生产调试，具有一定的指导意义，为离心转子式分级机的设计提供了必要的依据。更多还原

【Abstract】 The optimal operation of NHF-Ⅱ air clsssifier has been discussed by using orthogonal experiment, and the relstion between various fsctors and the cut size as well as the P8rtial classification efficiency have been analysed by means of regressive method. This study can aid production adjustmentand presents the principles of design of the classifier.更多还原
