How does "the shredder" work?

Obviously, everybody here is familiar with "shredder material" or something similar, as a class of ferrous scrap. And we all know that it's kind of a catch all class, for everything that we don't ourselves break down any further, if at all. My question is, how does a shredder work, and how does it separate the higher value, non-ferrous metals from the ferrous, and the garbage, like the plastic and rubber, and wood, and glass components? Or does it?

Anybody know? :confused:

There are several on Youtube. It first runs through and gets separated with large magnets - some while going through large "knives" on rollers. The magnets "pickup" the ferrous stuff while letting the nonferrous material fall into a separate bin. From there, it depends on the system they have. The more basic ones are simply crushers, like they put cars in and compact.

They had a show on tv a few months ago about e waste recyclers. They had a machine that sorted all the wire they tossed in there. Toss in a handful of insulated wire and the insulation went out on dispenser and the copper went out 2 others. Somehow, it sorted solder and clean wire down separate dispensers. I want one. I would be playing with that all the time.
