Building a crusher for copper yokes?

**ComputerScrapper** · 08-10-2011, 06:41 PM

Ok so there has been a lot of talk around the shop about finding a way to streamline our work on the copper yokes found on the back of CRT tubes. The best idea, so far, is to build some kind of crusher that would smash them and then the copper, plastic and ferrite could be seperated out.

The problem is that I am not very mechanically inclined. My partner is but we have been bouncing ideas back and fourth and we have not really nailed anything down that might work.

Does anyone have any ideas on something that might work for this? :confused:

I figure that the part that does the actual crushing would need to be extremely heavy but the question is what could that be?

Any ideas would be greatly appreciated.

Hey that's not a bad idea at all! I had not even thought of that. Thanks Dew! You the man!

Well if you crush it to much. still a pain to get copper from portions clinging to iron with glue, Naturally a small gentile fire works wonders as all you have is the copper on iron, from there a hack saw cut on one side delivers the copper in one bucket short in other. since the yokes are not #1 any way it works well with not to much smoke . check the local laws that's for TV's
The CRT Yoke put in freezer over night in the morn whack with rubber maillot (the copper stays soft ).

I was thinking modifying a small trash compactor or some kind of hydraulic crusher.

We actually tried a trash compactor that was given to us and we could not get enough crushing power. I am sure that each one is different but we could not get it to work. The hydraulic crusher is an idea. I was looking at one but it was an old modified press. They wanted a bit too much for it.

a modified bearing press should work, just make sure you've got guards setup to protect you from shrapnel

sure but either way you got to hand pick and separate copper from plastic some are very intertwined and some have some metal with it . I think your ideas ok to get at the main yoke but what about all the surrounding copper that will not just pop out.

But here's and idea for under $300 even less if used - get a cement mixer put in some yokes & put in some large iregular shape rocks put mixer on let rocks do the work

are ya'll kidding me ????ok...I'll bite...how 'bout a hydrolic log spltter ??

Dee, see Kris Kringle's post above, I think he beat you to the draw, Texans are known for that kind of stuff,,

**Dumpster-Dee** · 08-10-2011, 10:46 PM

thanks Mechanic688 (lol about gunslingin'). I was so "agog" at the subject that I just overlooked that. I really thought everyone was joking !!!

sledge hammer? lol whenever I went to the dumps as a kid, my favorite thing to smash was tv's lol. The big boom was nice to hear, just hurl a rock at it from a distance lol

I like the cement mixer idea. I bet it would pulverize the ferrite, then pull out your wire.

That would be a poor mans ball mill. And you still have to pick out the ferrite, unless you have a large magnet.

Mineral spirits works wonders on that stuff, and it can be filtered and re-used over and over

How about....An air chisel! VROOOOOOM!

**metal gypsy** · 08-11-2011, 04:30 PM

You need to get one of those "big hammers" from the ring-the-bell game at carnivals.....

**ComputerScrapper** · 08-11-2011, 04:41 PM

Our neighbor let us try his log splitter today and it actually worked out pretty well. We put the yoke between two pieces of heavy steel and then crushed it. Still a little bit of a pain in the neck but much faster than simply tearing them down. Now it is time to find a decently priced splitter that we can permanently modify.

Does an 8 or 12 lb sledge hammer not work the same? I've always just smashed it with the hammer, pretty easy after that.
