Numerical Simulation on Effect of Pusher Frequency on Separation Efficiency of Two-Stage Pusher Centrifuge

Abstract With advantages such as large capacity of production，low power consumption，big solid content and so on，pusher centrifuges are widely used in chemical industry，food industry，defense industry and others.And the two stage centrifuge is the most broadly used model.The pusher frequency is a very important parameter for the twostage pusher centrifuge and it plays a decisive role in the centrifuge production capacity and the separation efficiency.In order to study the effect of pusher frequency on separation efficiency，the FLUENT software is used to create threedimensional model and to simulate it，which took a P-100type twostage pusher centrifuge for example.The results show that the higher the pusher frequency is，the greater the production capacity will be.In the meanwhile，the filter cake solid content would be reduced.Therefore，various factors should be considered to determine the pusher frequency of the centrifuge in the actual production.The results also provide a series of references to optimizing the design of the centrifuge structure.
