    Abstract: A magnetic can separator which is specifically constructed for assuring the separation of all-aluminum cans from steel and steel-aluminum cans. The separator includes a magnetic drum onto which cans to be classified are directed and there is a deflector plate spaced from the path of the drum a distance such that a can must be disposed parallel to the axis of the drum before it can pass the deflector plate, thereby assuring that any steel component of a can will be attracted to the drum and will be delivered to a receiving area in exclusion of a receiving area for all-aluminum cans.
