Abstract: Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper wire bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper. A secondary copper recovery conveyor having a field of nails or spikes may be added subsequent to the last primary conveyor for enhanced yield of copper wire.

Abstract: Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. Shredded matter, or ASR, is sent through a series of sorters before reaching a system that separates out copper bits.

Abstract: Systems and methods for separating heavier from lighter materials in mixed auto shredder residue (ASR) from end-of-life vehicles. Vehicles are shredded and the resulting mixed ASR is fed into a system that efficiently segregates heavier (typically metal) from lighter (typically plastic) pieces. The system has an inlet feed chute angled downward to a lower end over a separator tank filled with water. One or more nozzles configured to introduce water at a velocity into the separator tank create a flow of water across the tank to push smaller and lighter particles over an exit weir. Heavier particles sink toward a heavy matter removal conveyor having a lower end positioned within the separator tank so that the heavier particles are transported upward out of the separator tank. The heavy matter removal conveyor may be one or more Archimedes screws, a flat, ribbed or cleated conveyor, or a drag chain.

Abstract: Systems and methods for separating materials and recovery of valuable materials such as from end-of-life vehicles and appliances are disclosed. Vehicles are shredded and resulting pieces are dropped into a fluidic separator that separates the shredded vehicle scrap into heavier pieces and lighter pieces. The fluidic separator separates the bulk of the more valuable metals of the non-metals. The fluidic separator, which may be used for separating many kinds of mixtures of pieces of varying specific gravity, comprises a fluid-filled container in which the pieces and the fluid are stirred so that pieces of specific gravity greater than that of the fluid tend to sink and pieces of specific gravity less than that of the fluid tend to float.
