The experiment equipments used to test the separation performance of hydrocyclone are briefly introduced. The CFD model and disperse phase model are also proposed to simulate the fluid field of hydrocyclone. The relationships between separation efficiency and flow rate, the flow rate and pressure drop, the particle diameter and grade efficiency are given. The pressure distribution along the z-direction is also presented. The results are compared fairy well with the experimental data.
