Abstract： To verify the feasibility of using discrete element analysis software EDEM in tile powder pressing, the process of tile powder pressing was simulated by the discrete element software EDEM. The dynamic simulation of multiple sets of tile powder pressing was conducted by the method of control variables. The relationship between pressing speed and pressing force was obtained through analysis of experimental data. The results show that both pressing force and density of the compacted body increase with the increase of pressing speed with other conditions being the same. The simulation results using EDEM software are consistent with actual working status of presses.
