Claim Text:
1. An aluminum can cleaning system for separating magnetic materials and other debris from aggregate comprising aluminum cans, said aluminum can cleaning system comprising: a conveyor for conveying an aggregate from a conveyor receiving end and discharging the aggregate at a conveyor discharge end, said conveyor including a magnet configured to cause said conveyor to retain a magnetic portion of the aggregate along a portion of said conveyor to separate the magnetic portion from a non-magnetic portion of the aggregate; an intake chute positioned proximate said conveyor discharge end to receive the non-magnetic portion of the aggregate discharged from said conveyor; an air duct having a first end in fluid communication with a lower end of said intake chute; a blower configured to provide an air flow from said lower end of said intake chute into said air duct, said air flow being of sufficient magnitude to carry the non-magnetic portion of the aggregate along said air duct; a channel in fluid communication with a second end of said air duct, said channel having a screen positioned therein, said screen defining openings sized to allow a debris portion of the non-magnetic portion of the aggregate to pass through said screen and to disallow aluminum cans from passing through said screen, said channel defining an opening proximate said screen to allow aluminum cans to exit said channel; and a bin disposed proximate said opening to receive the aluminum cans exiting said channel.
