- Abstract
Numerical simulation of liquid-solid two-phase flow was used to analyze the flow of the fluid in the classification chamber of ultrafine powder centrifugal classifier. Under the condition of the steady state, in order to study the influence of different blade angles on the classification performance, Eulerian multiphase flow model, RNG k- turbulence model and multiple reference frame (MRF) method were used to analyze the velocity distribution of the fluid in the classification chamber. On this basis, under the condition of the unsteady state, in order to study the influence of different classification wheel rotate speed on the cut size, the discrete phase model (DPM) was used to analyze the rule of particle track in the classification chamber. The results indicate that: when the blade angle is 15~30°, the classification performance is the best; When the blade angle is 30°, the cut size is close to 1 m when the classification wheel speed is 1000rpm; The cut size is close to 0.5 m when the classification wheel speed is 2000rpm; The cut size is smaller than 0.5 m when the classification wheel speed is 3000rpm. The simulation results well agree with the experimental results.
