摘要： A printed wiring board, on which an electronic parts are mounted and fixed by way soldering, is introduced into a heating furnace for heating at a temperature higher than or equal to a melting temperature of a solder. After sufficiently melting of solder, an impact force and/or a shearing force are applied. By this under a reduced connecting force, the electronic parts are removed from a printed wiring board. On the other hand, since the parts can be easily removed from the printed wiring board. Also, the parts and the printed circuit are separated for collecting useful substance and can improve resistance to enhance recycling efficiency.

摘要： The method of recovering valuables from a printed wiring board on which electronic components are mounted, includes the steps of (a) removing electronic components from a printed wiring board on which the electronic components are mounted, (b) polishing a surface of the printed wiring board from which the electronic components have been removed in the step (a), (c) milling the printed wiring board a surface of which has been polished in the step (b), and (d) separating milled portions of the printed wiring board into portions mainly including copper and portions mainly including resin and filler. The electronic components recovered in accordance with the method includes valuables such as gold having greater grade than natural minerals. The copper recovered in accordance with the method includes no impurities such as solder, and thus can be reclaimed as metal resource having high added value. The residual glass fiber and resin scarcely includes impurities such as solder, and thus can be reused as a filler to be used for building materials and construction materials.

摘要： A hollow rotating drum 1 is provided in an oblique manner and is rotated by two pairs of rollers 3a, 3b. A size classification unit 2 is provided in the vicinity of a center of the rotating drum in a lengthwise direction of the drum, and water is added from a water addition unit 4. An object to be moisturized is supplied from an opening on an upper portion of the rotating drum in a supplying direction 5 of the object. Then, the object is moved spirally within the rotating drum to be moisturized. An object, i.e., a moisture-processed substance having a size equal to or smaller than the predetermined size is classified by the size classification unit to be continuously discharged in a direction 6 of movements of the moisture-processed substance. Also, an object, i.e., residue having a larger size than the predetermined size, is continuously discharged from an opening on an underside of the rotating drum in a direction 7 of movements of the residue.
