<p>PURPOSE:To separately recover a foaming gas and a heat insulator resin after separating a foamed heat insulator in high efficiency and, at the same time, without a change in quality and to obtain equipment for the purpose. CONSTITUTION:The subject equipment is equipped with a separating part where foamed insulators are separated by a crusher 3 made up with a high speed rotator 5 having plural protrusions 4 from complex materials containing foamed insulators, a selecting part where heat insulators are selected by a wind power selector having an angle of inclination 67 which is larger than the coefficient of friction of a wall between the base board 11 of a wind tunnel and the plastics, etc., and is capable of sliding on an inclined plane against an upward wind in the wind tunnel and a bursting part where isolated bubbles in the selected foamed insulator are burst by an outward force and the separated foaming gas is cooled to a liquid.</p> |
