The Continuous Formation of Small Binary Composite Granules by a Single Rotating Conical Vessel with Grinding Media

Abstract

In order to form small spherical composite granules continuously by a simultaneous operation of granulation, grinding and separation using a single rotating conical vessel with a grinding media, experiments were carried out with CaCO₃ and SiC powder as binary solid materials, and with water as binder.
It was confirmed that the size of the composite granules decreased with increase in the feed ratio of binder to powder, and the size of SiC agglomerates contained in a composite granule depended on the volume fraction of the SiC component in the granule.
