To carry out the shape separation of irregular-shaped fine particles, a rotating vibrating conical disk separator was developed, and its separation characteristics were investigated by using fine particle mixtures differing in shape and size under various operating conditions. It was confirmed that relatively good performance was obtained for particles about 30 to 50μm in diameter under the optimal conditions. The conical disk adopted in this paper was effective for the shape separation of fine particles because the disk was able to diminish the adhesion of particles to the disk, and to promote the rolling motion of useful spherical particles in the radial direction of the disk.
