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. At least one separating machine receives the at least one second crushed electrical product from the second crushing machine to separate into three general categories: the metallic portion, the non-metallic portion, and a mixed portion having metallic and non-metallic subportions. The mix…
