Numerical simulation of particle mixing and granulation

In this work, the granulation process is simulated using the DEM software of Rocky®. The simulation process is divided into three stages: mixing of dry materials (0–30 s), granulation with water addition (30–60 s), and sieving (60–150 s). In the simulation, the rotating drum has a diameter of half the size of the laboratory equipment.
