Will it blend?

On steroids...

I have seen these kind of things on the "How Things are Made" program.  They dismantle these thing in the shredders, and the conveyor then transports the "mulch" to a processing station where they can separate the steel/iron with magnets.  Following that the process gets really high tech - the mulch travels on a very fast conveyor and is "X-Rayed" to determine what is metal and what is not - then as the mulch comes off the end of the conveyor and begins a free fall - little blasts of air are used to deflect the individual particles into different chutes or bins.  The aluminum/copper/brass are saved - the "fluff" is sent to a landfill or some other process.
