Applications and Selection Criteria. Milling media and grinding balls are used for milling or grinding processes to crush, grind and mill various materials. There is a variety of milling media materials such as: Steel (chrome steel, and stainless steel, 304SS and 316SS) Ceramics (agate, alumina, yttria stabilized zirconia, zirconium silicate ...
In this video, I start by showing that homemade black powder doesn't burn very well if the ingredients are only ground separately with a coffee grinder. Then...
thanks Randy on March 24, 2013 at 1:34 PM Good article Harry, Now you should investigate the alternative way to make superior Black Powder. Those prilled Potassium Nitrate crystals will dissolve in heated water and so there's no need to premill.

Ball milling Black Powder with ceramic media Hello all mad scientists out there! I would like to know if anyone has any experience with ball milling Black Powder with alumina balls and whether it is hopeless to attempt to, or not? The reason I ask is that I am a bit in doubt whether this particular type of ceramics are sparking or not.
Step 1: Parts and Tools. Below are the parts and tools that I used to make this ball mill. However, keep in mind that these are more guidelines than anything, and I encourage you to experiment with different sizes, parts, and designs. Parts: 1 length of PVC pipe (I used 6" of 2" diameter pipe) 1 PVC flat end cap. 1 PVC male screw adapter.
I've made some pretty good black powder using a coffee grinder and porter porter and pestle, but I was looking into getting a ball was going to get one of the cheap 70 6lb rock tumbler and modify it per skylighter's directions, but I would still need to get media to fill it half full, 200 1/2" balls.
As far as placement of your mill, the ideal distance is probably around 150ft or more away from any buildings of any sort. If you can barricade it that's even better (things like sandbags). Just make sure you don't block off air to the motor. When making black powder there is always a chance for it to go off.
Yttria stabilized Zirconia (YSZ) media for planetary and roller ball mills. YSZ is one of the most universal ceramic milling medias. It is very corrosion resistant, very wear resistant, hard, stable in acid solutions, and because of these properties they are essentially noncontaminating to your sample. Density: g/cm 3.
Removing Mill Dust from Mill Jar and Separating It from the Media Wet Granulating the Black Powder As it is right out of the ball mill, the mill dust will burn very rapidly with a "whoosh" if a small amount of it is lit with a fuse. To test this, lay out a short, 1/4inch wide line of the mill dust on a suitable outdoor surface.
Ball Mills. In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
Pyrotechnics. ball milling black powder. hondo. ActionTekJackson. Simoski. Arthur. ×. I have been ball milling my bp for a year now, and lately my powder is clumping up in the mill, it use to come out nice and fluffy. Whats happening, is the potassium nitrate or sulfur absorbing moisture and causing the clumping problem.
Milling Black Powder posted in Pyrotechnics: Just wanted to get a poll on varying options of most efficient yet safest way to mill black powder without a ball mill. I used to use a coffee grinder however the last time I milled some I resorted to a mortar and pestle instead, which was far too much work.

To grind a single chemical (vs. a mix like black powder) using a ball mill, fill your mill jar half full of hardened lead or brass grinding media, and 25% full of potassium nitrate. Turn the mill on and come back in an hour. Your nitrate should be light and fluffy. If not, continue grinding it 'til it's fine powder with no chunks or grains.
The maximum power draw in ball mill is when ball bed is 3540 % by volume in whole empty mill volume. Considering that ball bed has a porosity of 40 %, the actual ball volume is considered to be ...
Ball Mills Lead Media 6 Lb Rotary Ball Mill Kit 0 Kit Includes 6 Lb capacity DOUBLE Barrel ball mill. Perfect size for milling 2 different comps at once in separate drums. (2 barrels measures " high x " in diameter). Grind most materials into a fine powder in just a few hours.
A ball mill, a type of crusher, is a cylindrical device used to grind chemicals or mix compositions. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium, ideally non sparking milling media like lead balls. An internal cascading effect reduces the material to a fine powder.
Posted October 1, 2017. While BP has been made without a ball mill for years, professionally a wheel mill is used, early history was the use of a manual stamp mill, there is now no justification for failing to buy the basic minimum rock tumbler, which is usually available for below £100. A charge of suitable lead or ceramic media ...

The ideal milling method for optimized black powder milling involves what is called "cascading" action. This is a continuous flow of media file: ... Figure 2 shows the active grinding area for an optimally charged ball mill. As the drum rotates, the media should ideally form a sloping pile that maintains a 45 degree angle so that there is a ...

Ball milling media consists of wet, batch units in which water or other liquids and additives aid the grinding process by reducing friction and providing cooling. Ball grinding media uses an abrasive bonded to a wheel, belt, or disc to remove material and improve surface finish.
milling, sift out the media, put the powder in another container, add about 12. tablespoons of 70% isopropyl alcohol for each 100 grams, and thoroughly stir, then let dry. If you want to press it through a screen, add a little more. alcohol until it become a thick paste (not too runny).

The potassium nitrate is a bit tougher to mill completely in such a small jar. If the media is larger than 3/8", the efficiency drops off. I only mill the nitrate for 2 hours though. So, with 8 hours of total milling time (with no risk of explosion), you can produce 300 grams of excellent black powder better powder than if you milled it all ...
The media media most used in all milling applications are made of zirconia. But if the purpose of ballmilling is to blend materials softer than zirconia, alumina media is recommended to avoid breaking the dispersed powder. Using grinding balls with different diameters, 3 or more, improves the particles dispersion in the ceramic slurries.
I just ordered my first ball mill. It is the Dual Drum Rotary Rock Stone Metal Glass Tumbler Polisher 6 lb Total. The media 100 balls of Lead .50 Cal, 495 diameter Roundball Muzzeloader Speer Shot. I am still setting up my work space, containers, getting ready for my first project, reading my books and formulas, terms and forums.
My very first ball mill such as it was used a few pounds of stainless steel nuts and bolts for the medium charge. Ball bearings are very good for milling. Muzzle loading balls are, also. Fishing weights work (egg weights are about the best). Marbles work. Some people (scaring me as they do it) use glass marbles to mill black powder. LLoyd
These applications encompass powdering food products, grinding glass, creating ceramic glaze, formulating custom varnishes, producing black powder, and pulverizing various chemicals.
Mix for 4 hours in the ballmill with brass media; 2. 75% potassium nitrate. 20% sulfur. Mix for 4 hours in the ballmill with brass media; 3. Mix the two compounds in the ballmill WITHOUT the brass media for an hour. Of course between the first and the second step the barrell and the medias must be carefully cleaned!
