yes i spelled recommended wrong at the end but i only saw that after i saved the video. i can't be bothered to go change it, too much waiting for loading.
I'm very curious, has anyone tried this?
i would but you need a kilm to melt cans and a place where you can spark up a grinder and a vacume at the same time with out people crying about the noise and lets not forget you contaminate it with the abrasive particals from the disc . i would suggest to get a large coarse metal file double cut over 10 inches and just vacumeou the left overs and spare your lungs
I would if it was a shtf situation but for now i can just buy in bulk and have it shipped to my door.

Heck no. I’d prefer to not breath in aluminum dust.

The aluminum will have a lot of the abrassive wheel in it. But it may not matter for your purposes. Very creative how you collected it.
ashman none ya a very small amount of the abrasive did end up in the powder but it was negligible. I've now moved in to simply ball milling aluminium powder used for paint pigment, it's fine enough to work for thermite but not fine enough for flash powder. Not long after I posted this video I tried to build a much bigger ballmill( a project I abandoned for several difficulties) for which I bought waaaay more steel balls than I needed and so I used some in my small ballmill which up untill recently was out of action due to it losing 3/5 drive belts in less than 2 weeks because of our summer heat. I had an amazing idea to make a mould of a drive belt and then cast it in silicone rubber with reinforcement in it and now the ball mill runs amazingly. Using the steel balls made a massive difference in the grinding time so I could grind much more powder in the same time. I've heard many people say that it could spark but I did a lot of research and found 0 cases where it actually happened. I thought about it and there actually aren't any conditions that would cause it to spark, there is powder between the balls, the velocity of impact is waaaay to low etc.
I have made a ten kg firecracker,thank you
I wonder if a cyclonic separator would be useful here. To prevent splashes being sucked up by the vacuum, you might just put a vee shaped baffle in front of the suction tube. nice video... thanks
If you are not in a hurry and you have enough open space, consider this. After shaking aluminum/water mixture to insure even distribution of aluminum dust, let water evaporate. Works best in low humidity settings.
Oh I don't use this method anymore. Stopped using it shortly after making it. I get aluminium powder as resin pigment which is about 200#. I just ballmill that
Actual grinding at 5:22.
I’d get a narrow and wide step drill bits and slowly drill wholes through it and catch the shavings under it. Use the narrow one first and drill all the way through. Then hit it with the bigger one. Then blender it, then ball mill it. Wear all your PPE.
I'd imagine that that would create shavings that are too big to mill. I tried using small lathe turnings and it just wouldn't grind down. It needs to be a sand like material before it gets milled otherwise it will take weeks. Blending metal shavings seems to only screw up the blender. What I use is 200# aluminium powder used as a paint pigment. Takes 8 days to mill fine
@@HomeGrownPyrotechnics it might be less work and more safe just to buy it. I saw 5 pounds of 2 micron dark Indian aluminum for about $70 shipped. If your interested I’ll go and see if I can find it again in my browser history. I’d be nervous to play with that small of a powder myself.
Yeah unfortunately 'just buying it' doesn't work in my country. Pyro specific chems are pretty much impossible to get here. If I want it I must make it. The only thing I've had to import is parlon
@@HomeGrownPyrotechnics understood. I read that a “seed grinder” also works for the initial pulverizing of stuff. I’ve never looked into though.
I didn’t know milling took that long. Its alot more low profile though than purchasing anyways and you get the fulfillment of doing everything yourself.
Ya I get a lot of pleasure out of making things myself. I even make my own ammonium perchlorate. That was a 4 month project to get right lol, but because I now have all the equipment, I can easily make more.
Get chips from a machine shop. Clean the chips with either soapy water or kerosene. Let them dry. Ball mill to oblivion. Once ground to silvery dust add some stearic acid and charcoal as a phlegmatizer and grinding lubricant.❤
I have a lathe. I've tried milling aluminum turnings. It doesn't work. Would take months to mill down. It has to already be a sort of powder before going in the mill. I use aluminum powder resin pigment, works great. It comes as ~100-200 mesh and can be milled down to airfloat in less than a week depending on how much is in the mill
Rhello: a question, if this formula mix with water to make a solid paste would be correct?
im sorry, ive been trying hard to understand your question but it makes no sense.
#HomeGrownPyrotechnics.
Thank you. Sorry for the afternoon of my reply. I am looking for this formula to harden as a dough and adhere to cardboard as glue. That it is not only dust, but also paste as solid glue. Type sticky putty.
I'm still confused. The video is about making aluminium powder. Not glue
#HomeGrownPyrotechnics.
Hello: Sorry for my way of explaining, I don't speak English 100%. I am looking for this formula to adhere or compact. That your body is not powdered if you do not paste, something more solid. The example I mentioned is the glue that has that consistency. Also like kite pills. The point I want to get is the following: Do you know the red cartridges used in toy guns? When you shoot a thunder sound is heard? I share the link. m.czcams.com/video/i0J-G8tGHPA/video.html I'm also looking for the formula for this pop pop snapper product m.czcams.com/video/LozzeUYFJKI/video.html. Thank you very much for your answers, I appreciate it very much. Sorry for my English 😂😂😂. Regards.
@@QKLIENTE the cap gun mixture is an explosive mixture called Armstrong mix, made with 50/50 potassium chlorate and red phosphorus, both can be gotten from Mach boxes. The pop pop things are small rocks coated in silver fulmanate I believe. I hope that answers your questions
He just showed you how to make a Huka bong.
A belt sander works better with less labor. The particles are low velocity and easy to catch.
Whatever works
Have you tried a ball mill with actual rock like say granite that act's much more like sand paper than actual steel balls also have you tried a bench grinder with an stone wheel in a large plastic tub with a lid ? And some sort of vacuum like you already have in the video but with a bench grinder and holding the melted metal with steel pliers to the grinder ?
Rock will chip and fracture off and contaminate the aluminium. Where would you get granite balls anyway. Also I don't think you understand how ballmilling works. The balls are crushing the material as the balls tumble. Also I now use aluminium powder used for resin pigment. It already comes 200 mesh so I ballmill that.
Screen out the sand aluminium being lighter would seperate deferently to the heavy sand just need a two screens and a trap for your heavier sand wouldn't it do the same for steel balls so you don't have a early thermite reaction with the aluminium powder if it was to get hot enough and you had the right amount of rust to fine aluminium ratio in your Ball mill just thinking outside of the Box dosent have to be the same way everyone else makes it the granite would be easy to obtain simply from a creek bed or beach already on a round shape just need to find it
Lining the inside with rubber matting helps a lot too won't wear out your drum so fast
The steel isn't flaking off during grinding so isn't mixing.thermite also takes very high temperatures to ignite. Rocks are also a bad idea because it can generate sparks on impact. Steel takes much more force to do the same. Just drop the rock idea, its a bad idea in many ways.
@@thehardrockminer8778 the drum is MADE of rubber my guy. A very stiff rubber. Anyway the only thing that there is any concern for being worn out is the drive belt which can be replaced
simple solution. very good
Really cool, are you south african?
I am yes, you as well?
Find a friend with a Lath the Chips and Shavings are fine and will break down very fast in a ball mill
Fred Nordhorn I actually have a lathe now, I got it mid november. I'm also building myself a rather large ball mill with the intent of grinding the aluminium turnings but I'm struggling to find some parts I need to Finnish it.
Lath are inch and a half by quarter inch wood strips!
Milling chips are good too.
One needs to go-to Germany and bring back a large amount of dark German pyro! Regulations are being further inforced these days!
Just make it yourself? It's not hard whatsoever
@@jacobkudrowich Canada i'm guessing?
i dont understand why you would make it so complicated?
I made due with what I had available to me. I wanted to make this as an alternate method than the usual coffee grinder destroying method of grinding aluminium foil.
He's probably making thermite...or should be, since they aren't allowed any way to defend themselves.
That sounds a damaged drive shaft it’s the sound of the motor slipping inside the shaft because you out too much load on it it sheared the drive shaft just so you know if you take it apart you will see the motor spins fine sounds fine when not connected to drive but has chewed the drive this is in my experience because what you have ground is stronger than the material the shafts made from
Also be careful of sparks which will blow up your powder it’s why you should use a sparkles motor on a lead loaded ball mill but ultimately I’m here looking aren’t I
if i remember correctly from the years ago i made this video, i took the motor apart and the thing that held the drive shaft at the back of the motor was warn a little bit and had some play which is what caused the rattling, nothing could be done, the motor was buggered, had to get a new one. also, you definitely don't want lead, aluminium is harder and you will just end up with lead powder in your mix. i use steel balls now. say they spark and ill fight you. I also use aluminium powder now that got from a moulding supplies shop, buy it as a pigment
bro
What is the exact amount of powder of this aluminum? Is 25 microns less or less?
I don't know. It's just termed airfloat or dark aluminium
@@HomeGrownPyrotechnics after need the have ball mill?
@rawandgaming7113 ballmill is required yes
@@HomeGrownPyrotechnics very good
thanks bro
Why not just use a hand sander....?
im pretty sure that that would take much longer. besides, i dont use this method any more, im currently ball milling some course aluminium powder i bought as an epoxy pigment and it works much better and faster seeing as the particle size of it is already smaller. i also am using steel balls which greatly speeds up the process
Those are some great points and I agree with most of them but i was just reccomend ing an easier way to get aluminum powder because most people don't have ball mills and grinders and stuff
the problem with that is it is a shit ton of work for very little result. also without a ball mill, you can't get the super fine powder that you need for pyrotechnics, and i mean SUPER fine, way more than any high grit sandpaper can give you
That is true I guess ball mill is the best route
Have you thought of putting some sort of reducing agent in the water, so that the Al gets coated with it, preventing oxidation of the surface? I believe charcoal is used during the ball milling of some products. The water provides one with the opportunity to disperse a reducing agent more evenly, which might result in a nice even coat. Just wondering.
the thing is that the aluminium has to be oxidised during the whole process because as it gets finer, it gets more combustible and if you mill it for like a week without letting air in, its said that it will oxidise so fast that it will catch fire. the oxidation of the metal surface is instantaneous and forms a very thin oxide layer which then prevents further oxidation so i think that it wouldn't be needed to is some sort of reducing agent. i anyway have a lathe now and can use the turnings and im in the process of building a muuuch bigger ball mill for making aluminium powder but there are some parts that i need that i cant find.
Altho this is an old video, grinding aluminum powder with water is not a good idea. Aluminum powder create a exothermic reaction with water and produces hydrogen and heat. Can spontaneous ignite. Use some sort of thing oil instead
you would have to wash the oil out then. i observed no such reaction even when looking for it. i no longer use this method and now simply ballmill aluminium powder used as metal pigment in resin.
Try a fine rasp in a recip saw, much cleaner process and end product.
And gives a very unrewarding yield. Tones of work for very little product. It's much easier to ballmill with steel balls using aluminium 200# powder used as resin pigment.
@@HomeGrownPyrotechnics steel? Man that is literally playing with fire. You should use glass or ceramic.
Sigh. I tested it thoroughly. Steel balls in a ballmill don't even come close to reaching the velocities required to sparks to form inside a ballmill and the powder being milled absorbs the energy to grind down fine. That's the point.
I used long exposure photography at max iso to record if any sparks formed when struck with another steel ball free falling from 1 m in the air. A ballmill cannot achieve such velocities and absolutely no sparks were seen zoomed in
@@HomeGrownPyrotechnics static electricity with steel is the concern, or at least that's what I was taught.
I would think that grinding would cause so much heat that you would excessively oxidize the aluminium
Nope. Heat only comes if you grind it too long without letting air in then expose it to air. The oxidisation can be exothermic. I've experienced it igniting just sitting on my table because I wasn't giving it enough oxygen in the final stages.
i just realised you were talking about the grinding from the angle grinder and not the ballmilling. the surface area of the particles when angle grinding is insignificant at that size for oxidation to be an issue. one thing to keep in mind is that aluminium oxidises instantly in contact with air and forms an oxide layer, that's part of the appeal of aluminium as that oxide layer prevents further oxidisation, ie, it never rusts unless in some very harsh conditions. that instant oxidation can also be a problem tho as i mentioned with it catching fire after ballmilling. oxidation is exothermic so if its happening fast enough, it can start a fire
I have done most everything else. Beautiful. I have all parts you need. Thanks.
Hydrogen gas?????????????? BS
the aluminium doesn't react with the water, the particle size is too big
Scared to use it i have an 20 year old Industarial grinder that a few years ago started to sound like a cow on steroids it has many things loose inside that rattle ale the time and smells like an electric fire after a few seconds of operating it and i still use it all the time different standards bro
If you're confident to use that thing you are truly bad ass.
Be careful! the aluminium reactd with water and generates Hydrogen, you should change water to oil or something
That would only be of concern if it was a micro sized particle already. Aluminum instantaneously forms an oxide layer on its surface that prevents any further reactions in its environment. This concern mostly applies more to magnesium which WILL react with water as a powder. Besides, I stopped using this method shortly after making that video several years ago. I got hold of aluminium powder used as paint pigment which is about 200#. I just mill that
Ok thanks for letting me know :)
Way too complicated. Use a ball mill with ceramic balls or glass marbles.
What's best ratio aluminum and charcoal for dark use?
Not sure, but I think when I made 40g of Al powder I used a gram or two
One problem with this idea, how does one make 400 mesh flakes? Spherical shape gives off sparks..no bangs! Using aluminum foil doesn't work... tried ideas from CZcams and a book bought from a pyro supply.. none of these work! I read info on the internet that German dark pyro mesh flakes are are made from aluminum on paper ..kinda like on Wrigley's chewing gum paper ..now where did I read that?!?? Burnt or sprayed in a very finely divided cloud which is very DANGEROUS and bad for the eyes and lungs !!! The methods I see on CZcams don't work too well for firecrackers! ! I gave up ....
The dark aluminium i make works very well for making flash for firecrackers. If you want 400 mesh you will need a 400 mesh screen and need to ball mill the powder then sift it. Ball milling generates flake aluminium because the grinding media is constantly flattening and grinding the particles.

Why not just put foil in the ball mill??
I'm pretty sure that all it would do is just scrunch the foil into balls and it won't grind it
@@HomeGrownPyrotechnics are you certain or are you pretty sure?
@@Preppapigslays umm does it matter? i know what happens inside a ball mill and that's what i foresee happening

I tried buying it?:) it not that expensive.
Aluminum is very cheap!
What if you can't find it hmm? Then you have to make it. Not everyone has access to the same materials as everyone else
I'm no pyrotech. But like reading on the hobbie. There is a cheaper way ask a machine shop if there doing aluminium work filling from lathe are milling can have lots problebly be free .
I found an easier way of making dark aluminum powder since this video. I got aluminum powder used as pigment for resin and I ball mill that.
