The aluminum is separated from the other materials using an eddy current. An eddy current actually repels the non-ferrous (non-magnetic) metals and throws them from the rest of the metals from which it is being separated. Aluminum cans and non-recyclable trash on a conveyor is run over an eddy current rotor. The spinning of the eddy current rotor creates a field of energy around non-ferrous items and these items are repelled from the rest of the material. So the aluminum cans are "thrown" or "pushed" off the sort line into a container while the non-recyclable trash falls into a trash container below. >> Next >>
