Abstract
In order to investigate separation performance of a wet shape separator developed for fine particles, experiments were carried out using binary solid mixtures of about 50-250μm particles with different shapes. As a result, it was found that; (1) the separtion mechanism of separator was based on the difference in static rolling frictional characteristics between spherical and non-spherical particles on a rotating conical disk in liquid, (2) continuous shape separations could be achieved by sweeping particles on the rotating conical disk by liquid jet, (3) separation efficiencies depended on various experimental conditions, such as surface roughness of disk material, particle size, flow rate for sweeping particles, surface inclination angle and rotational speed of conical disk, (4) even mixture of fine 50μm-sized particles could be effectively separated under appropriate operating conditions.
