Abstract: Superfine comminuting mill with turbulence is a new model of processing equipment. In order to improve the processing results of superfine comminuting mill with turbulence, it necessary to cognize the flow field frame and flow state in the concave. In the present paper, a simulation model based on the experiment equipment with the software Pro/Engineer is devised. With the help of advanced CFD technology, based on the turbulence model and the SIMPLEC method, the sin gle-phase 3-d turbulent flow is simulated in the FLUENT software. Through giving the cloud-picture of velocity, total pressure near blades and path line of concave, property of flow field frame is showed directly. It is useful for cognize the flow field frame.
