It probably sorts by mass as all of the pieces are the same size. Not sure if this is what it's doing, but for example aluminum and copper bits of the same size go down a shoot, the aluminum would not travel as far as the copper after leaving the shoot. Put one bin closer to collect the aluminum, and one farther to collect the copper.
