The evaluation of the powder properties of the granule feed material for ferrite material production is very important. The fundamental properties of a powder are the packing characteristics and the flowability of the particle bed. In this study, we investigated the influence of the granule size distributions on the void fraction and the angle of repose of the granule particle bed. We found that the size distributions, which had the minimum values of the void fraction and the angle of repose. The compression test of the ferrite granule particle bed was conducted by using a pellet test machine with the peculiar plunger and vessel. Our results confirmed the correlations between the powder properties and its compression characteristics in the granule particle bed.
