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

[Harold_V]

Yes, Ray, they are simple, but they are also critical of a few factors.

The principle involved in a ball mill is that the charge of balls, which must be heavy enough to destroy the feed, is taken to the apex of the curvature of the cylinder, then dropped. It's the dropping balls that do the work, therefore two factors are important. One is that the diameter of the cylinder must be great enough to allow the balls to accelerate, and the balls must be large enough to impact the feed with enough energy to break it. Otherwise the balls don't hammer, but simply rub the material intended to be crushed.

Assuming those two criteria are not met, there's as much wear on the charge and mill as there is on the objects intended to be crushed, making what has the potential to be a fast operation one that is painfully slow.

Harold is absolutely right! Again!
The amount of the balls(or media) is another factor. size and weight also
are important. As Harold said if done right it can be a relativlely fast operation. Or it will wear the media as much as the work!!
Speed adjustment can get the media to fall properly if size and weight are close and the same product is always run!!...
The machine you were looking at is one type of a hammermill like the IHC
Machine i have..That type usually is run wet. I would like to build a small
sample hammermill. I don't always have a lot of material to run but want to sample different semiconductors..NEVER pay $700.00 for a simple machine like that.It is way overpriced!.A hammermill shredder is very fast and the IHC will take a 2"diameter piece of granite and make dust out of it in about 2 seconds!! Send me a pm and i'll see what i can do.The IHC will chew up plastic connectors fairly fast also!
Good luck and email is [email protected] Bernie

I said it was interesting, not practical.

 

[Bernie Foley]

Scott2357,
Please accept my appology for offering too much knowledge on the subject of the hammermills.After 30yrs of repairing and fixing like equipment i just don't even like talking about them so much for my two cents...I was an maintenance engineer for 40yrs..I'm also a retired jeweler and tool and die manufacturing engineer....Now lets talk about something more pleasent!........mrfixit39...How about gold refining!

 

[Anonymous]

Hmmmm, as Harold said "balls don't hammer, but simply rub the material...." Sorry, better get my mind back on the gold...ROFL

 

[Scott2357]

Bernie,

No need to apologize. Information is what we're all here for, the more the better. That gizmo seemed way overpriced to me too but very interesting since I had not seen one before.

Firewalker,
Have you thought about motorizing that meat grinder? saw off the clunky handle, adapt a pully to it, maybe even a hopper and a chute? possibly a patent? (lol!) It is definitely a better mouse trap!

 

[LeftyTheBandit]

I bet you could use a garbage disposal unit from an old kitchen sink.

I think they are mini hammer-mills.

 

[Harold_V]

I'd be inclined to agree with you, although the expected lifespan would be short. They aren't intended to grind abrasive materials, so they'd degrade rapidly. Those I've seen have hammers that pivot on large rivets. Wouldn't take too long to wear them to the point of failure. Such a unit would, however, be far better suited to crushing than a blender.

firewalker! Wait a second...that last chip in your pics looks like a rare one that I've seen before! You would have to check the numbers, but it seems identical to one that has sold for $1,200 working! I hope you haven't ground it up....

Check this site. http://www.cpu-world.com/CPUs/68000/

All of those on that site are rare and very much sought after by collectors. It is not a completed list by no means, so even if the munbers are different but they are styled the same, you can probably sell them for much more than the gold content!

 

[Anonymous]

Ooops, guess what? Thanks for the info. I should have more l;ike that somewhere....JAck

 

[LeftyTheBandit]

Rednecks dont sell cpu's! We grind em up reeeal good! :wink:

Check out page 21 of the catalog from Action Mining in Sandy Or.

Check out the back cover (of the Action Mining Catalog) and you can see the ore pulverizer is a grain, corn, cereal mill. They also state that it is not for production use and they sell replacement plates and replacement auger so they obviously wear out.

I'm not trying to discourage anyone from trying it but expect it to wear out. I almost bought one once but they talked me out of it. I still might get one someday but would try to find it locally to avoid the shipping cost or at least check the price.

If anyone has one and tried it, how does it work on ore or chips? I saw a video years ago from action mining and they turned the handle back and forth and not just one direction. I expect the rocks were jamming up. It was obviously not for pounds at a time but looked quicker than a mortar and pestle.

imsg171s-35 made by Minmus A

looks like the 8086 by motorolia, all prices said call, checked out several places this early pm. The largest lot from the manufactuors was like 15. They all said call for price, whereas the insg171s-35 goes for $200 this looks like it will go for way more.
would take a pic but havent figured out my new digital camera yet.

 

[hoardpm]

WOW!!!! Never thought of that. When my grandparents sold there house they had an auction. I bought 4 of these for some reason . Now I retire them from there curant roll as gigantic paper weights.

The best piece of equipment I've ever used for crushing ceramic ICs was a sort of slow motorized rolling mill. We bought it for a song at some used equipment place in L.A. It was said to have been used for manufacturing paint. It consisted mainly of two adjustable steel rolls, about 6" dia. and maybe 12" long, set side-by-side at the top. The parts were dropped down between the rolls. A removable hopper, which was handy for certain items, came with it. I think it even worked well for plastic parts. The entire unit wasn't very large - much smaller than you'd expect.

Just going through some old messages and realized that this post started out using a Meat Grinder and what I seen was a grain mill. I have an old meat grinder somewhere and will have to dig it up and give this a shot. I don't expect it would crush chips to a fine powder but should break them up. Worth a shot,

 

[DNIndustry]

I picked up an electric ice crusher from the 70's for 2 bucks. Ill have to give it a shot.

Shames less plug, It took me 10 months to hit 100 posts.

What about the "Will It Blend" blender? :lol:

That seems to chop up everything...
