Abstract

PURPOSE:To separate a brittle degradation layer on the surface of granular matters and to regenerate the used resin by giving force of mechanical deformation including rotation to the granular matters into which a molded product of used synthetic resin is cut. CONSTITUTION:A molded product of used synthetic resin is cut finely into granular matters of 1-10mm., preferably, 3-8mm., these matters are inserted into a separating device 11 and the brittle degradation layer on the surface of the granular matters is separated. The separating device 11 has an opening 28 in the central part. And it has, in multiple stages, fixed disks 27 each of which forms a rough face 29 in one direction at least and rotary disks 30 each of which has a shaft of rotation coaxial to the fixed disk and a rought face 31 facing the rough face 29 of at least one fexed disk 27 at an intended internal. And the shaft of rotation of the rotary disk 30 is provided with dampers 40-44 supported so that it can move vertically.
