ABSTRACT:
An apparatus separates a substantially metallic portion from a substantially non-metallic portion of constituent components of at least one electrical product, comprising a plurality of crushing machines, such as a first crushing machine, a second crushing machine, and a third 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. The third crushing machine crushes the at least one third crushed electrical product to create at least one third crushed electrical product. The third crushing machine has a third screen affixed thereto to regulate a third flow of the at least one third crushed electrical product from the third crushing machine. The at least one separating machine receives the at least one third crushed electrical product from the third crushing machine to separate the metallic portions from the non-metallic portions of the at least one electrical product. A plurality of air separators may be used to remove non-metallic light weight materials from the crushed electronic products to deposit in a collection bin and to return the portions of the light weight material that comprise metallic material to the stream of crushed material. A plurality of conveyors may also be used to transport the at least one first, second, and thrid crushed electrical products to and from the first crushing machine, the second crushing machine, the third crushing machine, and the at least one separating machine.
