The Sustainable Development Goals were adopted by the United Nations in 2015. Technologies that realize an economically low-carbon society are attracting attention of the international community. Regarding powder processing technology and device development, we will introduce examples of technological development that contribute to the achievement of the SDGs (Sustainable Development Goals).

It is important to consider the equipment wear in bead mills to maintain quality and control operational costs. In the conventional wear simulation, mesh deformation is applied using wear laws. There is a problem that the mesh is broken when large mesh deformations occur. We propose the wear simulation model which represents shape deformation by the interface capturing method in this study. The proposed model is robust because the model deforms equipment shape without requiring mesh deformation. Moreover, proposed model reduces computational costs by coupling with IB-DEM (Impulse-Based Discrete Element Method) which allows for a larger time step size than conventional DEM. We demonstrate the wear results when significant shape deformations occur due to collision with beads. We verify the proposed model by comparing the numerical results with actual worn parts by applying to the dry bead mill.
