“…This software is based on the DEM which is a powerful tool to simulate particulate systems. 4,14,15 DEM software uses Newton's law [16][17][18] to describe the motion of each particle (Eqs. 1 and 2) and the interaction between particles based on the initial particle characteristics…”

“…[1][2][3] Batch mixers DEM has been used to study the particles behavior inside mixers or similar equipments to obtain a better understanding of these systems. [4][5][6] The computational capacity is an important factor to decrease the simulation time, and at the same time is a limiting factor. An option to decrease the simulation time is the use of twodimensional (2-D) simulations.…”

“…An option to decrease the simulation time is the use of twodimensional (2-D) simulations. Xu et al 4 used DEM to simulate a quasi 2-D experimental process demonstrating that density and particle size affect the final uniformity in the system studied and found a relationship between the rotation ratio and the flow regime obtained. Chaudhuri et al 6 used the DEM to study the effect of cohesion in the mixing process by comparison of the simulation results with experimental images of a similar system.…”

Powder mixing is an essential operation in pharmaceutical, food, and petrochemical industries. Pharmaceutical companies have been working in the implementation of continuous processes as an alternative to the batch process using the food and drug administration process analytical technology initiative. The main goal was to understand the mixing phenomena inside the continuous tumble mixer and monitor blend uniformity using discrete element method. Results demonstrated that the main mixing mechanism is convection similar to the common tumbling mixers. This mechanism is driven by the bulk flow of the particles, due to the mixer rotation. The simulations' results, demonstrated that the cohesion reduces the concentration variability due to the higher holdup, particle interactions, and mean residence time. The blend uniformity at the exit of the system was measured and a relationship between relative standard distribution, cohesion, and the collision frequency was found.

“…DEM is a good method to investigate the particle behaviors in the rotating overcoating drum [3]. The rotating drum has been used in many places, and the mixing behavior with internals has been studied in many reports [3][4][5], but the radial mixing was often focused on.…”

“…The rotating drum has been used in many places, and the mixing behavior with internals has been studied in many reports [3][4][5], but the radial mixing was often focused on. Also the mixing time is an important factor in the overcoating process, which has not been paid enough attention in the previous studies.…”
