分割粒径 meaning in English

cut diameter

Abstract : in order to improve the performance of a vortex classifier , a certain type of narrow plates are fitted in the passages between the blades in the rotor cage . this measure results in reduction in the cut size and increase in classifying precision . more significant effect is observed in the case of the rotor cage with fewer blades originally fitted . it is pointed out that the reason is due to the decrease in inertia counter vorticity
文摘:在涡流分级机转笼通道中心加装窄叶片使产品分割粒径减小，分级精度提高.转笼径向叶数较少时加装效果明显，径向叶片数多时效果不明显.分析指出，这是减小了转笼径向叶片间惯性反旋涡强度的缘故
