  • Patent number: 7252250
    Abstract: The invention provides a method and apparatus for recycling toner cartridges. A shredder breaks up the toner cartridges into pieces, thereby releasing any toner from within the otherwise substantially sealed cartridges. The toner pieces along with any free toner powder are then fed through a separation stage including a mechanical separator and a trommel separator. Each separator employs a sifting screen, which allows smaller particles to fall through the screen while holding back the larger pieces. Both separators agitate the pieces to mobilize the smaller particles. A vacuum extraction system is used to withdraw air from around the cartridge pieces and an air ionizer is included for feeding ionized air into the apparatus to reduce any static electronic charge buildup. The toner is then removed from the extracted air by a dust collector.

  • Patent number: 6300402
    Abstract: An apparatus separates a substantially metallic portion from a substantially non-metallic portion or constituent components of at least one electrical product, comprising a plurality of crushing machines, such as a first crushing machine and a second crushing machine and a separating machine. The first crushing machine crushes the at least one electrical product to create at least one crushed electrical product. The first crushing machine has a first screen affixed thereto to regulate a first flow of the at least one first crushed electrical product from the first crushing machine. The second crushing machine crushes the at least one first crushed electrical product to create at least one second crushed electrical product. The second crushing machine has a second screen affixed thereto to regulate a second flow of the at least one second crushed electrical product from the second crushing machine.

  • Patent number: 6216967
    Abstract: A process is disclosed for disaggregating waste materials which contain at least partially reusable elements, mainly metals, plastics and cardboard. The waste materials are stirred in water by mechanical forces, large pieces, in particular plastic pieces, are coarsely crushed and soluble elements, in particular cardboard, are dissolved. The metallic elements are separated from the suspension as heavy materials, the remaining coarse solids, in particular plastics, are mechanically separated from the suspension, and the suspended fine solids are separated from the suspension by dewatering.
