A numerical study is carried out to investigate the combined influence of material properties and process parameters on coating quality in a high shear mixer (specifically an FT4 Powder Rheometer) to construct a regime map. The Discrete Element Method (DEM) is employed to simulate a range of material properties (size, density, and surface energy) and process parameters (impeller speed and mixing time) via Design of Experiments (DoE). A robust regime map is proposed for prediction of dry coating performance based on dimensionless Stokes deformation number (St
