PROBLEM TO BE SOLVED: To provide a machine for separation/recovery of gypsum and laminated paper in a gypsum plaster board waste material, which is capable of efficiently separating the gypsum and laminated paper in the gypsum plaster board waste material from each other with high accuracy. SOLUTION: This separation/recovery machine is provided within its machine body frame 1 with a conveying device 2 for conveying a gypsum plaster board waste material X in a platelike form as it is, a laminated paper stripping device 3 for stripping laminated paper Z being in both the surface and rear of the gypsum plaster board waste material by scraping away the laminated paper Z from the waste material, a paper piece discharge device 4 for discharging each of stripped paper pieces Za to the outside of the machine body frame 1, and a gypsum core crusher 5 for crushing a platelike gypsum core Y of the gypsum plaster board waste material X, remaining after the stripping of the laminated paper Z, into small pieces. Thus, by only supplying the gypsum plaster board waste material X in the platelike form as it is, from a waste material supply port 11, the gypsum plaster board waste material X can automatically be separated into a laminated paper fraction and a gypsum component fraction with good separation efficiency and good separation accuracy, and accordingly, the laminated paper Z and the gypsum component can separately be recovered. |
