Non-Chemical Grinding IC's, the Rednecks way LOL

[Anonymous]

I tried this old meat grinder for breaking up IC Chips. For the plastic ones, it works great. Also for the ceramic processors and chips, it is a bit harder, but still works great. For the demo pics, I ground full chips at once, but did find it easier to break the chips with a hammer before grinding. I got the old grinder at a garage sale for 50 cents.

Great idea, I would think that incinerating your feedstock would greatly improve the the finished product.

You may encounter some zinc scrapings from the galvanized coating from the grinder being introduced into the equation.

Ok, ya got me for a new-be. Incenerate before or after the grinding? Also would that be before any acid usage? Jack

I was introduced to using one of those old grinders by a man named Wally Koz. He showed me about grinding my blacksands concentrates to liberate more fine and extra fine gold. It works well for prospecting and should work well for your application.

Oh, have you ever thought about building a jig so you can use a powerdrill to turn it rather than turning the grinder by hand?

That's great. I bet your hand would be tired after grinding up a few pounds. :shock:

I'm still perfecting CPUs in AP. I had a few test batches that went poorly. The best results were with larger ceramic pieces. (Gold caps, small shards and dust withheld from the reaction bucket). Hit the pins and cores, save the stripped ceramic. All that dust and detritus seems to
cob-up the process.

I'm new here so I don't have any proven methods yet, but I think a hydraulic press might do a better job.
You could make a steel containment pan for the press plate to fit into so flying chip bits would not be lost.
The press plate and the pan plate would need to have irregular or grooved surfaces to aid in concentrating
pressure points for efficient use of crushing force. Preferably plates would be inverse patterns of each other.
I can't give a good reason, but I would probably process chip pins and lid plates first then crush packages.

Check out http://www.harborfreight.com and word search for 'ton press'.
You can get up to a 20 ton model for less than $200. Much less if you only plan to crush plastic chips.

Hmmmm, $200.00 vs 50 cents? LOL

 

[Scott2357]

Well, I guess it is a little pricey compared to a 50 cent meat grinder but I was thinking long term here. Besides, it has a lot more uses than cracking chips.

To name a few..

Prospectors could use it to crush gold/platinum ore.

If you're into catalytic converters and hate cutting them open (as I do), you could partially crush the bodies :twisted: so the fractured honeycomb pieces would just pour out the end.

... and no blistered hands!

Long hours, blistered hands and sore backs.

Mother Nature does not give up her treasures easily, the ore must be ground to the consistency of flour.

Your hydraulic press will at most crush the ore.

Just kidding about the $$. Bu tyou can also grind meat with this thing, I guess you could make hamburger pattys with the press. Just kidding, the press is a good idea. Gustavous, does that mean I should run the grind through again for a smaller result (Newbee question again)?

Fashion yourself a box out of metal. Fill it with goodies to crush. Turn on 2-3 angle grinders and throw them in. Cover and wait. Good times...

It's a bit of troble sifting the road bed, though.

 

[overneo]

Crushing CPU's, okay. But what to do next with the powder : directly chemical process (HCL + H2O2) or something between?

Hi Jack and nice to see you here.First I know that redneck comment is directed towards me (lol) and second you need to shave.Hope your doing well and cant wait to see pics from those pins.

What about using a ball mill tumbler to tumble everything down to dust?

On the side, would roasting the dust be necessary then? One could tumble anything, ore, sand, IC's/CPU and honeycomb matrix from a cat converter.

I find frequent references to roasting such materials, what does this step do?

Thanks

Hi all,
Thought i would put in my 2 cents. I found an International Harvester
shredder at the dump..I put an electric motor on it. The 4hp engine was
junk. It won't do much more than leaves twigs but it works great for small stones/ore and ic's and plastic connectors. Have to change the output screen for the size particals wanted. You don't want copper wire int though
unless you like a birdsnest of it!!!.. It has flails that rotate. The boss lady
would have a fit if i used the $6,000.00 MaCissick chipper/shredder we have!!......Good luck....Bernie

I found an interesting gadget...

http://cgi.ebay.com/11-Inch-IMPACT-...oryZ3360QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

It says it crushes CPUs to 400 mesh!

Why in the world would you want to spend $700+ dollars for that gizmo?
I bought a small ball mill for under $100.00 works just fine.. I bought more gold with the balance of my savings. Just a thought...

Figure out what you need to make your own. Ball mills are a simple item,
all that is needed is a motor a tub some shot and rollers. I have seen several nice units on this forum with all the info needed to build one.
Sorry another thought...
