Aluminum powder is readily available on the internet, and you can buy it from a source like eBay for as little as $8.00 a pound. If you are a bit enterprising you can even make your aluminum powder which will turn out cheaper in the long run, but you will have to enhance your setup a bit – a blender and a ball mill being the main additions.

Building a Ball Mill for Grinding Chemicals. Aug 11,, Learn how to build a ball mill for grinding solids into fine powders, used in chemistry and in industry to grind hard solids to a very fine powder, If you are grinding metals like magnesium, aluminum, etc, or other material.
A grinding circuit simulation combined with ball weal law was used to determine the optimum composition of the make-up ball sizes in tumbling ball mills. It was found that the optimum composition depends on various factors, including the feed size, the product size, the mill diameter and the breakage parameters.
Wiki says "A ball mill is a type of grinder used to grind materials into extremely fine powder for use in paints, pyrotechnics, and ceramics." Many instructables refer to United Nuclear Ball Mills. Their small ball mill cost between $70 and $80 dollars. For no more than $30 and in 5 minute you can build a ball mill of appreciable performance.
Production of aluminum powder Aluminum powder was originally produced by using a stamp mill to create flakes In the 1920s E J Hall pioneered the process of spraying molten aluminum to make powder droplets Get Price Ball mill Wikipedia The ball mill is a key piece of equipment for grinding crushed materials and it is widely used inAluminium ...
By vigorously shaking or high-speed rotation, a high mechanical energy is applied on the powders because of collision with heavy balls [10]. A type of ball mill is shown in Figure 1 [12]. Mechanical ball milling has been used to blend aluminum with magnesium and carbon in order to alter its chemical properties and combustion behavior [14, 15, 16].
for the aluminum powder if you just going to make a batch to play with than the best way to go is just buy it, you can get it on ebay for about $12 per pound, the finer the better. if you are going to be makenig large amounts quite frequently the best way to go is to buy a ball mill to produce a fine powder, (rock tumblers are the same thing ...
Make the jump to see the mill in action and get the grand tour. If you need more tumbling power, use a dryer motor ! Posted in Tool Hacks Tagged ball mill, balls to the wall, glass, grinder ...
Figure 17.6 Methods of mechanical comminution to obtain fine particles: (a) roll crushing, (b) ball mill, and (c) hammer milling. F. Mechanical alloying. 9 Powders of two or more metals are mixed in a ball mill (see fig. 17.7). 9 Under the impact of hard balls, the powders fracture and bond together by diffusion, forming alloy powders.
The ball mill is the best way to grind and you can also grind all the ingredients for black powder together. A ball mill is really a rock tumbler. The rock tumbler is usually made of hard rubber at least on the inside. Mine has an aluminum plate inside the rubber lid to help give it rigidity but when it is closed up, there is no exposed metal.
Ball mill your aluminum for 11-14 days for excellent results, ultra fine aluminum powder and overall a bigger BANG with your flash powder. Step 3. Mixing the ingredients. A good step for beginners would be to make a 10-gram mixture of the flash powder. NOTE: Never make more than 30 grams of flash powder unless your are a professional and/or ...

8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter (Figure 8.11 ). The feed can be dry, with less than 3% moisture to minimize ball …
about 25 vol% of powder is added along with about 1 wt% of a lubricant such as stearic or oleic acid. For wet milling, 30-40 vol% of powder with 1 wt% of dispersing agent such as water, alcohol or hexane is employed. • Optimum diameter of the …
Place the small pieces as much as you can into the grinder, tight the lid, and grind the aluminum turning. Clean the aluminum. If using aluminum cans, use the sandpaper to remove the paint, and...
Homemade Double-Barrel Ball Mill Ball milling replaces potentially unsafe hand grinding of chemicals and compositions. The crushing of the material is accomplished by the repeated falling of heavy balls onto it, over and over, inside the mill jar. So, it …

This is the DIY ball mill I built for free for making aluminum powder in bulk for various thermite reactions, as well as flash powder (hopefully) in the futu...
As far as dark aluminum goes, I have read that adding 5% fine charcoal will make suitable powder. "Take a third part of a grain of fulminating silver, and puy it into the wick of a candle, which is to be burned by the peron you wih to surpise. Similar tricks may be played by placing the silver in a pair of snuffers, boot, shoes, walking-stick, &c."

3. Aluminum oxidizes on contact with oxygen and blending it uncovers new surfaces. When you open the lid, oxygen pours in, and if the powder oxidizes fast enough, then it will get hot enough to ignite. To avoid this, open the lid at least every ten to fifteen minutes. Make sure you mill your aluminum in a well-ventilates area and let the powder ...
The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum 'chunk size', product size as P80 and maximum and finally the …

So I found a scrap piece of aluminum and mounted it the end the drum walked toward to act as a stop. The drum riding against the smooth aluminum surface doesn't seem to produce much friction. The ball mill is powered by a fairly robust 12V DC motor salvaged from a junked printer. It had a pulley for a fine-toothed belt on it.
