Abstract In this study, we investigated the relationship between slurry and spray-dried granule properties. Various slurries were prepared using different sizes of Mn-Zn ferrite particles and evaluated using flow curve and adsorbed dispersant amount measurements and sedimentation tests. Spray-dried granules were evaluated using morphology observations, density and strength measurements, and compression tests. The results demonstrated that a slurry with a relatively high particle dispersion could produce a solid granule with a relatively low density during spray-drying. The results further suggested that the change in a slurry's particle dispersion and flocculation state during drying strongly influenced the granule morphology.
