Thanks for your suggestions!

The shredding action was actually ok. To a blender with a glass bucked will do that job well.

I also asked the guys from the perpetual plastics project and they will offer a shredder in the 400$ range as well in the future.

What I also found out was that if you melt you plastic on a baking sheet you get it thin enough for you kitchen blender to be able to work it. Its hellishly loud and you need a sturdy glassbucket but for the lowcost version it will do.

Morbid tip:  If you're looking for an industrial grinder, call around to your local crematory (pet or human) and see if they have an old one to sell.  (That's how they make the ashes.)

Do a search for commercial grinders and you will find some very good designs and if you check the equipment auctions every month there are always a few that go pretty cheap and are still quite serviceable albeit not pretty or new.
