| Abstract: | A blast numerical simulation within an enclosed model has been carried out based on the Computational Fluid Dynamics （CFD） method. The basic particles motion rules of the air and steel grit under the blasting condition are revealed and the initial velocity, gravi- ty and vacuum pressure＇s influence on the recycling efficiency are studied. According to the particle traces and the influencing factors, the model optimization has been done in order to promote the efficiency of recycling. |
