machine for Aluminium powder

[buonapptito]

ho visto il tuo filmato e ho trovato interessante la macchina che hai costruito.... ti volevo porgere una domanda la parte cilindrica usata come mola di che materiale e fatta???? ma sopratutto e ruvida e se si di che grana???? spero mi risponderai!!!!!!!! grazie mille Max

[minninulsi]

doesn't it react with the water as soon as the oxide layer is removed?

[Super73VW]

Three BATF agents didn't like this video.

[AZKOJYUN]

would a metal file be better or worse?

[AKAtheA]

so.... what's the final cost of the powder?

[biggunn770]

doesn't it put the media in to the aluminium? If so, wouldn't it be bad to use as a flash base or r-candy base making friction when mixing the part A and B chems

[UTubeisSHIT523441]

good setup and video

[UTubeisSHIT523441]

damn, I have just thought about the same setup..(with water I mean)..

[MrDpsc]

can you send some to me? :D

[NilsJ75]

thx for the good instructions

[came750]

Hey! I wondered a bit about how fast the engine hovers. and what pulleys you use? I have a pretty similar engine that you use.

[Digadogup]

is it cheeper to do it this way?

[nJkiLlz101]

what kind of sandpaper do u use and how do u hold it on there because i uses normal sandpaper on mine and it came rite offf help me plzz

[ahmedalwitry]

cool

[ElliottEnterprizes]

im having a problen with mine, when ever i turn it on it goes grand for a few seconds then the paper rips or the sand surface of the paper comes off leaving the paper behind. i think it has something to do with the fact that im using water what type of sand paper do you use?

[TakaiMaboroshi]

could the aluminium get burned?

[randyclar747]

make me one of these machines, and I will buy it. I can see myself trying it, and water leaking all over the place, through the axle. Or: driving all over the place trying to find a motor like I have been.

[randyclar747]

Does the water in the pan react with the metal you are trying to grind? Esp, Aluminum. I think it does, correct me if I am wrong.

[darkfang77]

@randyclar747 Unlikely, if it did, then the probable compounds you would get would be AlOH, but you tend to get that with group 1/2 metals so no it wouldn't react.

Of course, I might be wrong myself.

[randyclar747]

I really like this, but don't know where to start.

[randyclar747]

I really would like to learn more about your machine. I live in farm country, so I do not know how readily available the supplies are. You have a unique method zijo3, after much thought, I think you really got it going on. Teach me.

[randyclar747]

Whats the difference between this and ball milling the aluminum, any real difference.? Plus I imagine you get hellifying dust in the air, inspite of the water in your pan. I did watch visit the gamekeeper sight by the way.

[zijo3]

@randyclar747  there is no dust in the air. I don't know about ballmiling aluminium.

[darkfang77]

@randyclar747 With ball milling you tend to get more flake shaped particles, with abrasive means, you can get granular types more.

[randyclar747]

@darkfang77 How do you make a machine like this, without getting dust in the air? I am certain crude versions of this machine would do exactly that, dust the air. Aluminum poisoning causes dementia, and slows down mental capacitity; my health I cannot risk.

[darkfang77]

@randyclar747

Well if the grinder was actually under the water, then the aluminium wouldn't go into the air?

Use dust masks?

Have well ventilation?

Making the machine won't be cheap anyway, if you're after small amounts - buy it.

[randyclar747]

@darkfang77 Yeah I am tired of paying 22 dollars a pound for pyro aluminum. There has got to be a less expensive way to get this stuff, when market price for aluminum itself is.30 a pound. Where do you buy this machine? Where do I look online? Google metal grinding machine?

[darkfang77]

You're being overcharged for the stuff.

You don't need the pyro type unless you're making fireworks ,etc.

You can get the instructions online as I've seen them before.

If you can't make the machine, then here are some places.

Metal Foundries (ask for Al powder)

Paint Stores (VERY Hard to get)

Theres also a website called "united nuclear" Google it.

Al powder is also used for resin making and boat building I think so check out any stores related to resin making,etc.

If all fails, try eBay.

[randyclar747]

@darkfang77 Thanks for all your support. I'd rather make this machine or ball mill aluminum foil cut into shreds. I think either would work. Leave the ball mill running for weeks, with heavy steel shot in it, its got to be ground to dust. If you can offer any advice on how to make this machine, I know I can grab any scrap al, and pulverize it for a tenth of what I am paying for pyro aluminum. Yes, I make some fireworks, and al is always a main ingredient.

[darkfang77]

Have you heard of a rock tumbler? Many people use it to make ball milled Al.

I've heard that the rock tumbling technique is great for making german/indian dark type al powders. So perhaps that might suit you?

Personally, I'd love to get my hands on some Al powder, but most of the time its either too expensive or too time consuming (to make my own) so I wish you good luck in making your Aluminium powder! And enjoy using the stuff as well!

[randyclar747]

@darkfang77 Asbestos fibers get into air easily, down to particles to small to see when getting rid of it, in a controlled environment, even after wetting down the air. Particles manage to get in the air, no matter how much water you use, but it really helps cut down on amount. I have licenses in lead and asbestos removal. Similar to this in the creation of dust.

[starshock01]

@randyclar747 it looks like it makes finer particles faster then ball milling, and the water causes the dust to sink and prevents it from exploding, essentially with ball milling water would be placed in the mill for the same reason

[mormanman13]

@randyclar747 ball milling alluminum does not work. the media doesn't have the hardness or abrasiveness needed to turn it to powder. you can mill mgal but only b/c it is bittle. Al is strechy and soft. Make sense?

[bas12345654321]

@randyclar747 This method is a fast way to "sandpaper" the aluminuim to dust.

The water makes the aluminium not "fly away".

Ballmilling is only to make the powder smaller, ore when you ballmill aluminiumfoil you get the same result.

[tallthor]

where can i get an aluminum tube like the one you have? From Lowes or something like that? Or can i use an aluminum bat or something more accessible?

[TheBombBros]

its a type writer wheel with sandpaper wrapped around it. it sais so on the site in the info.

[soverato3]

were you use it fore ???

(fireworks)????

[acerkiwi]

THERMITE

[100000000years]

thermobaric weapons

[hpibigfan]

when i first saw this i knew exactly how it worked

[goukbearpig]

imagine when the cops walk in im sure they wont think its a meth lab

[TheBombBros]

you can filter the powder through a paper coffee filter. it works extremely well. i copied your idea and made my own machine. i will soon post a video on it.

[ladedk]

@TheBombBros

Anyone ever tried "airfloating" it with an aquarium pump or something similar? or is this not necessary at all?

[TheBombBros]

it might not be neccessary. becuase it is already somewhere between 400 and 700 mesh. (at least with my machine) not sure bout the one on this video. but the Al is so fine it wouldnt make a large difference

[TheBombBros]

nice.

[fafafabianfafafa]

doesn't the aluminum powder get rusty ????

[jsmithmilitary]

no its aluminum not iron

[useopenstupid]

pmsl ;)

[MacsCanfly]

id die for that

[FeuerUndZeug]

fine powder, fine machine. Only some sulfur is missing ;-)

[mzaul]

I like the sound of it (especially at 0.47), reminds me of an old marine dieselengine=)

[luthmhor]

So ive got the machine mostly finished. Everything except the component that holds the metal as it grinds etc.

When i held the metal by hand for testing, i found that the powder clumps together. Is it because the particles are too big, and are forming clumps? Have you had any experience with this zijo3?

[zijo3]

no?.  maybe you have to coarse sandpaper, it's faster but particles are too big.

[rafarauen12]

This is a relly nice work man !

I will try to do the same, because paying 17 bucks a pound is way too much when you use it alot!

[berger1980]

$17 a pound? Are you in the states? I normally pay $4-9 a pound for Eckart...

[warinmymind]

You guys know you can just go buy an etch-a-sketch and bust it open for aluminum powder right?

[luthmhor]

Thats about as inefficient as you can get.

Using etch a sketches to get aluminum powder, is like using ipod screens to make all the windows in your house. It would take forever and tons of money to get enough.

[twitch738]

hey did you put that comment on another vid lol

[puppystomper324]

not really

[BenBC2008]

Are you sure?

[itsumonihon]

totally retarded, i hope to god that most youth of the future are not as dumb as you are.

[puppystomper324]

REALY??????????

[luthmhor]

Hey people, im going to try making something similar, ill post all the details for you, exactly what i used, the costs etc. Make it easier for everyone else.

[theitalian556]

Good Idea!

[luthmhor]

So I have pretty much all the materials i need now. I just have to start building the housing and putting everything together.

Im using a rolling pin i bought, with a 3/8" shaft, and 3/8" bearings. Connected to a 1750rpm 1/4hp motor, with a 2.25" pulley on the motors axle, connected to a 7.75" pulley on the rolling pins axle, to give me exactly 500rpm on the rolling pin (as suggested on that website).

[randyclar747]

@luthmhor How do you get a motor for this? Picture yourself living in the middle of noowhere, like me, and then tell me how. I live in midwest.

[luthmhor]

@randyclar747 check a hardware store for like a grinder (sharpens tools and stuff), thats what i had originally, but the RPM was probably too high for me to use it (to reduce the RPM to where i needed it i would've had to use a really big pulley, which isnt practical). I got lucky and my grandpa gave me the motor i currently use as well as all the pulleys, So try a hardware store. Some appliances have electric motors, check the newspaper or kijiji etc. You could buy one online but its more money

[luthmhor]

How did you secure the sandpaper to the roller?

[zijo3]

it's glued on.

[luthmhor]

Thanks for the reply. What do you do when the sandpaper wears out though? The axle for the roller their looks pretty thick, what is that 1/2"? 1/4"?

[zijo3]

try to remove old sandpaper and glue new one. because of the water it's not that hard.

But , it would be best to make it , so you can remove roller, or have easy access to the roller to change the sandpaper . I think the axle is 10 mm.

[luthmhor]

I see. Thanks.

Ive got most of the supplies i need. Tommorrow im getting the bearings and the belt, that should be all thats left that i need. I bought a grinder to take the motor from it, but the rpm turned out to be too high for much use (3600rpm) (reducing the rpm to around 500 would be next to impossible, without a HUGE pulley). But i was at my grandparents over the weekend and my grandpa gave me a 1/4hp 1725 rpm motor, so ill use that (he also gave me a whole bunch of different pulleys)

[randyclar747]

@zijo3 What grade sandpaper are you using to get 600 mesh powder? 600 grit?

[Moviemillionare]

a blender works better

[luthmhor]

How can it do better then what this guys machine did...no flakes. just pure powder.

[manstarson]

no its not a tube its a sandstone

[manstarson]

it will oxide in the water

[rcfreak2493]

nice dude thats impressive

[theitalian556]

hmmmm intersting how long does it take to make fine al powder? say 1000 mesh

[luthmhor]

Thats insanely fine isnt it?

[theitalian556]

ya it is my guess 600-1000 mesh, but who knows lol! I have made al powder that fine by ball milling it! which also produces al flakes which is great for flash!

[luthmhor]

Did you make the mill yourself by chance?

[theitalian556]

No, Im sorry I didnt! I bought a 6lb dual drum rock tumbler off ebay! It works great for making aluminum powder and other things!!!

[agent00redneck]

Instead of making your own comment, try to help answer someone Else's questions and make us all a bit smarter. We all want to make this machine and none of us know how, so make a comment that counts.

[RicardoGarciaPino]

is it using a tube with sandpaper or is it using two alluminium tubes against each other??

[agent00redneck]

Two aluminum pipes.

[d3eadinside]

i think its a tube of sand paper,they r hard to find haha

[d3eadinside]

wow this is a good idea lol

[uchiacon]

No wonder the authour hasn't replyed to you guys, you're a bunch of uneducated idiots.

[iknowad]

Actually this machine isn't that expensive. It just has a lot of parts. The only real expensive thing is the motor. This machine makes higher quality alluminum powder than a coffee grinder plus it makes it creates powder faster.

[menu12345]

dude i think it would be cheaper to just buy aluminum powder

[2ndMOoch]

aluminium poweder is hard to find

[menu12345]

Ebay, Skylighter, Paintshops, everywhere else online and u are here saying its hard to find

[randyclar747]

@2ndMOoch This is such a great idea this dude has. Since he can take any piece of aluminum and grind it. Aluminum is .40 a pound for scrap, and his end product sells for 20 dollars a pound. The creator of this video can become a millionaire easy marketing aluminum powder online to legitimate buyers.

[megafeltch]

dude, aluminium powder reacts with water producing hydrogen

[ther0flcopter]

lol.... no it doesnt aluminium reacts with naHO (sodium hydroxide) which is the acid in drain cleaner.

[megafeltch]

i know it reacts with sodium hydroxide but i was pretty sure it also reacts with water but more slowly.

i read that there is pyrophoric al

[d3eadinside]

wow lol

[therealmag]

Wouldn't it increase your productivity if you laid the bar down the grinding wheel instead of across it?

[agent00redneck]

You, my friend, are correct. But you would have to check the machine and rotate the pipe getting grinded more. This does not require any attention.

[erfergo]

Dude u can get a coffe grinder for like 30$....

[ampeyro]

i supose that the liquid is oil, 'm i true?

[RamiAtrash]

what is that rotating stuff?

[draconite420]

the belts?

[RamiAtrash]

no =) that cylinder thing that grind sheet of AL

[coffeebuzzz]

Mate, that looks pretty fucken dangerous.

[draconite420]

lol what? a pet toy poodle looks more dangerous than this machine.

Nice machine BTW, is that from a grinder?

[ToobeYoo]

Lol not bad... not bad at all.

[RicardoGarciaPino]

good video - im building one here in colombia, because aluminium powder is very expensive around here... but its very fun stuff...

[agent00redneck]

Can you make a video of it when you make it?

[nirvanafan833]

nice machine but wouldn't the aluminium react with the water to form aluminium hydroxide? probably why it looks dark...maybe you should use mineral oil or something that isn't volatile or flammable and doesn't react with aluminium.

[zijo3]

i don't think that aluminium is that reactive, i use solution of boric acid.

Yes, for magnesium is a good idea to use oil or something other than water.

[TruBluPyro]

wow, that looks like a really fine powder, it nealy looks a bit dark, ;) 5*

[powertotheslaves1]

genius

[moosey333]

the water is so you dont get all that tiny al dust in your lungs right?

[zijo3]

Yes. The finer particles float around in the air. And as a coolant, the metal and the roller get extrememly hot

[deweypotts]

What was the motor from?

[zijo3]

it's from a cheap grinding machine, i just installed two computer fan's. So it can work longer

[boney43]

Very informative vid. Thanks for posting. I live in the states and will probably make one like yours. People ask why when you can just buy it. When you make it at home you don't have to worry about some company ratting you out to the government to cover their own ass.

[pyrocrazzy]

whats the quality of alluminum, it looks a little dark to me???

[crazyboy0602]

What a waste this uses so much power for so little aluminum why don't you buy it?

[zijo3]

Why,do you know of any sellers in my country? :) I can make al, mg, zn, al+%mg powder almost with a push of the button, I'm not dependent on some seller, who can screw me.

It's a hobby, we make our own things

[crazyboy0602]

Keten might ship to you. Pretty green flames from APC is from Slovenia and he doesn't do this.

[corndog815]

how fine is this al?

[alucard1892]

how do you get the powder out

[Dupske]

heat the water up, and when all the water is disapiered you got the aluminium

[Davidnetanya]

is that aluminium powder can be used for thermite ?

[Xteam500]

yea

[Davidnetanya]

Thanks a lot, that's a really great machine

[displayfireworks1]

It doesn't get any better than that. Great job.

[700racer22]

where do u get that nice aluminum rods ive been trying to find aluminum for awile now...

[zijo3]

I don't know where to get them, i made them , melt scrap aluminium end pour in the Al tubes.

[montey1017]

@700racer22 It may not be immediate, but most small engine blocks are aluminum. salvage yards heve piles of these things they would love to get rid of. take out the innards, clean it off, and thats a solid lump of aluminum.

[sadbill2]

how do you get the aluminum out of the water

[zijo3]

let the alu powder settle, drain off the water, and then spread the powder on newspaper to dry.

[tTatmosT]

great machine n if it grings magnesium to even better... ur machine rocks!

[TNITRATO]

Thank you zijo3.

I have a great interest in build one of these nice machines for producing my own metal powders.. This is the only way I can think for powdering at home some metals like zinc and magnesium.. Fine Al poder can be obtained by puting several cut Al foils in blender and then ball milling the resulting product. Magnalium powder is by far the easiest to powder, since is very very brittle, and not very much difficult to make.. But powdering Zn and Mg is another history!

[TNITRATO]

How much fine is it?

Anyway great video. Thank you to share with us.

[zijo3]

I don't know the size, i don't have mesh screens, but is ok for stars,

Thanks for the nice comment.

[TNITRATO]

Have you used your machine for powdering Mg or Zn?

Also, about the sand paper: how fast you need to replace it (by wear)?

Thanks!

[zijo3]

Yes i used it for powdering Mg , and it grinds faster then aluminium, but the oxidation is a problem and i don't like to use dichromate.

I tried Titanium, end it just destroys the sand paper. Problem is choosing the right type of sandpaper (not just different grits and material but from different company's) , some stop grinding in an hour, this one i change around 30 hours.

[PhantomMaster101]

If they are made why not a large diameter ratstail file? There are useually metal supply companies that deal with these kinds of metals in larger metro areas.

[tittytwister5251]

man water and electrics do not mix!! nice either way tho

[REDP0TAT0]

oh and whats ur mesh?

[REDP0TAT0]

how much RPM? where u got ur motor from? how much weight on the aluminium?

ty RED POTATO

[zijo3]

I don't remember how much RPM. The motor is from cheep grinding machine, and i installed to fans to cool the motor. Tray this site ---

[rashean123]

do you have any problems with sand getting in the powder?

[zijo3]

"sand" is getting in the Al powder, but i don't think it's a problem, I use this aluminium for all my stars

[moreno666dead]

Do you use water or something else?

[zijo3]

I use water and a little of boric acid to prevent oxidation.

[Nighthawkinlight]

Great design, I'm surprised that the sandpaper will hold up underwater

[zijo3]

Thanks, yes it holds with the right glue, the only problem is choosing the right type of sandpaper, some stop grinding in an hour, this one i change after 30 hours.

[Nighthawkinlight]

Very nice. What is your grinding cylinder from?

[zijo3]

it's aluminium tube from a printer, and i filled it with cement, sandpaper is glued on
