A numerical model was used to predict and improve the flow characteristics in a hammer mill. For this purpose a CFD (computational fluid dynamics) model was built. SST and LES turbulence models was tested in order to improve the model. For the simulation of the sieve effect a porous domain was used. The pressure, velocity of fluid and also the turbulence areas were analyzed. The physical properties of the milled particles and the grinding process parameters are greatly affected by the fluid flow in the hammer mill and because of this, by understanding how the fluid flow takes place inside it can lead to a improved design.
