In order to produce small composite granules having binary components of CaCO3 and SiC powders, experiments were carried out by the simultaneous operation of granulation, grinding and separation in a single continuous rotating conical vessel with a grinding media. To characterize these composite granules, SiC agglomerates included in a granule were separated by chemical methods, and the size distributions of granules and these SiC agglomerates were measured by an image analyzer through a microscope.
The structure in a composite granule was characterized by comparing the size of a composite granule with that of SiC agglomerates in the granule.
As a result, it was found that composite structures in each granule could be classified broadly into six kinds of structure models, and that the composite structure depended on the size of the granules and the volume fraction of the SiC component in the granule.
