Abstract

PROBLEM TO BE SOLVED: To simultaneously perform separation treatment by difference in specific gravity and by screening by providing a vessel which houses plastic balls having specific gravity between that of materials of low specific gravity and those of high specific gravity in objects to be separated in layers and whose bottom part is formed into meshes and vibrating the vessel by a vibrator. SOLUTION: When separating waste calcium silicate heat insulators, crushed materials are fed to the shallow layers side of plastic ball layers and a vessel 1 is vibrated in the longitudinal direction. Then by difference in specific gravity between the plastic balls having a density between those of materials of low specific gravity and of high specific gravity in objects to be separated and the objects to be separated, calcium silicate lumpy materials to be reused remain on plastic ball layers. On the other hand, metal pieces or stones, wire scrap, chips of wood and the like sink in the ball layers and reach bottom meshes 2 and are separated. At the same time, calcium silicate pieces and granular materials pass through spaces between the balls 3 and sink and further are screened by the meshes 2 and recovered under the vessel 1.
