Digital Twin

This paper presents the application of a digital twin in industrial manufacturing with an impact pin mill and twin screw granulator as exemplar studies. A new particle breakage model subject to impact loading pertaining to the impact pin mill was developed, which enables the contribution of the normal and tangential velocity components to be rationalised. In the twin screw granulation, a coupled model with DEM and PBM is proposed with a new breakage kernel developed for the TSG. The application of digital twin is hoped to facilitate the understanding of particulate process and help transit from digital design to digital operation.
