Process for crushing IC/CPU's

[ctgresale]

Hey everybody, been doing allot of reading on here for months on different techniques to process IC and CPU while I collected enough stuff to process. Found allot of good info, but think that I may have found something that can save allot of time and I have seen a few other member talk about it but never any results if they tried. It's the Blendtec Blender. I had seen the video's on YouTube and looked like it was just what I needed, but I was going to have to sell some scrap first to justify spending 550.00 on one of them. But last week I found a seller on Ebay that had some refurbished commercial version for 169.00 with free shipping, so I went ahead and ordered one. It came in today and it looks like it is all that we will need to grind up IC's and CPU's. This spins at something like 1500 rpm's and is a IC crushing machine. I put a handful of 32pin eproms in there to test out and within 30 sec there was nothing but a fine dust. Also another good part of this being a commercial version, it has an external hard plastic housing that closes over the blender part and when it is closed it has another part that keeps pressure so the lid does not fly open for any reason. I just went back to Ebay and it looks like the 169.00 black ones are sold out, but he still has some olive ones at 199.00. I'll try to post some pictures tomorrow of stuff that I've run so everyone can see how it really works Also here is the item # that I'm talking about--- Item number: 390356091247

Thanks
Steve

How long will it last?

How long will it last?

With ceramics... no blade will last for too long...

 

[ctgresale]

not sure but will let you know if it turn out not to be long, also NEW replacement 36qt blender jar for 59.00 from mfg, btw there is allot of sparking that goes on durning a crush

btw there is allot of sparking that goes on durning a crush

Ayup!

That's the blades being destroyed. That's to say nothing of the bearing below the blades, which is now loaded with abrasive compounds that will shorten what little lifespan the blender may have enjoyed.

I don't recommend a blender for crushing ceramics for that reason. A ball mill is a much wiser choice.

go to youtube and look for "will it blend?" there is some funny stuff about those blenders.they were made tough but repeated use in that manner cant be good at any rate.

Well I can confirm that it will not last long. After few batches it will start smelling like burning plastic and rubber and you notice output is more and more coarse. Engine noise will change too. That is time to stop what you do as accident is waiting behind corner. I did the same thing but I have used it for grinding black plastic chips from motherboards and cards. It lasted about 5-6 batches.
Ball mill as Harold pointed out is right choice for ceramics. Plastic chips can be processed as I did - pyrolysis/burning in high temperature and then grinding in ball mill or hand held sort of mortar&pestle device.

Your material needs to be processed to the consistancy of baby powder to process it.

 

[ctgresale]

Thanks for the feedback, guess I go easy on it with the ceramic ones and only use it for the plastic ones, or maybe make some other kind of blade for it, something stronger

 

[patnor1011]

Well I destroyed mine on plastic chips to be precise. If you want that blade and engine last longer incinerate/pyrolyse them first, pre-crush them in some (pipe&cap) mortar and (rod) pestle and then try to crush to fine powder in your mixer.

 

[Harold_V]

Please examine your blender to see if the lower bearing (often just an Oilite bushing) is exposed to the contents of the blending cup. Lesser blenders are built that way, and are not intended to be used for such material. Yours may not be built the same way, but I have my doubts.

Unless you can isolate the material in the blender from the lower bearing, the life will be exceedingly short. The powdered material is very abrasive--so it destroys the bearing and shaft. They "self destruct".

I have used it for whole chips. Blades pretty much disappeared. Then I got aluminium one - coffee grinder and I use that on incinerated, crushed plastic chips - it reduce them to baby powder like consistency. I take out most of pins and inside metallic parts prior grinding. Works fine for me.

hey guy's just a quick question has anybody tried the crazy crusher made for rock sampling only it claims to take rock down to sand grain size and i would like to hear from anyone who has used one before i goahead and buy one
thanks guys
ps. its at crazycrusher.com

 

[glondor]

Hey Grim. If this is spam, at least it is usefull spam. That looks like a winner of a tool. Price seems ok as well.

 

[grim]

hi glondor
no its not spam well it wasnt meant to be just i saw a video on youtube and thought this could be just what i need and wanted to know if anyone had used it and what they thought of it as i have aprox 40 kilo's of chips from memory sticks that i have been avoiding doing anything with as breaking them down for leaching looked to be a real pain

 

[rasanders22]

That ore crusher looks promising. In the FAQ it says it has been used for CPU's. $300 dollars isnt a bad price either if you ask me.

Why do people want to pulverize CPUs?

 

[glondor]

Word is there is gold in the ceramic matrix. I cannot verify this. Yet.

Why do people want to pulverize CPUs?

I sure could use some help with this.
I built my own ball mill.A 22 inch beauty.I have only used it about 20 times on ceramic.On some batches that I process,I do quite well,and on others I recovery nothing.Can anyone try to explain what may be going on? I ran a batch 2 weeks ago,using a leach,and got almost a gram of gold from less than 10 lbs of powder.Next day,same process,very different result,almost nothing.Any ideas?

 

[patnor1011]

Any chance that it was actually left over gold from previous procedure? (like dissolving pins)
I understand that you processed already processed cpus. Am I right?
