Abstract
SLG continuous powder surface modifying machines have been widely applied in the powder engineering of China presently. Based on the industrial SLG-3/600 type modifying machine, a three-dimensional CFD model is developed to make the numerical simulations of the inner gas-particle flow field, including the gas velocity field, pressure field, particle concentration field and moving trace. The simulation results indicate that the velocity field and pressure field as well as the particle concentration field are distributed non-uniformly in the SLG modifying machine. Besides, a shortcut phenomenon is observed during the moving of the particles. The numerical simulations can not only depict the flow characteristics inside the SLG modifying machine, but also present useful reference to the mechanism study and optimal design to further improve its structure and working parameters in the future.
