An aluminum can cleaning system for separating magnetic materials and other debris from aggregate comprising aluminum cans comprises a conveyor having a magnet to cause the conveyor to retain a magnetic portion of the aggregate along a portion of the conveyor to separate the magnetic portion from a non-magnetic portion of the aggregate. The conveyor discharges the non-magnetic portion into an intake chute. An air duct has a first end in fluid communication with a lower end of the intake chute. A blower is configured to provide air flow from the intake chute into the air duct to carry the non-magnetic portion along the air duct. A channel is in fluid communication with a second end of the air duct. A screen is positioned along the channel to separate debris from aluminum cans and to direct the aluminum cans into a bin disposed proximate an opening in the channel.
