Abstract：Cyclone separator is one of the commonly used separation equipment in the process of preparing rare earth oxides by atomization roasting.In order to improve the separation efficiency of ultrafine particles in the calcinated products,Fluent numerical simulation and experimental verification were combined to obtain the optimal configuration of the cyclone separator.The particle separation efficiency and fluid pressure drop were evaluated to explore the optimization effect of the expanded structure cyclone.The results show that the separation efficiency of 1,3 and 5 μm particles is increased by 13.25％,42.33％and 44.02％,respectively,and the drag coefficient is reduced when cone height is 370 mm away from cyclone top plate and the Angle of expan-sion improvement is 10°.The cyclone separator of new improved structure can reduce energy consumption and improve the sepa-ration efficiency.
