This contribution is focused on mixing dynamics and homogenization process of the granular material via Discrete Element Method. The simulation is conducted by using open-source code LIGGGHTS. The mixing process of approximately forty-two thousand monodisperse spherical particles is simulated in a vertical cylindrical mixer with two opposed flat blades. The rake angle of blades is 45°. The mixing process was studied with varying blade rotational speed (from 15 rpm to 540 rpm), coefficient of friction (from 0.05 to 0.9), coefficient of restitution (0.1 to 1.0), Poisson’s ratio (0.1 to 0.45) and particle diameter (2mm, 4 mm). Each of simulated processes was performed for 80 stirrer revolutions.
