Before carbonization, the material was dried in an oven at 40 °C for 12 h. The material was then ground in a planetary ball mill (type: Retsch PM100) with four 40 mm diameter balls at 250 rpm for 2 h, with counter-rotation occurring after 1 h to reduce the size of the large particles, to a powder consistency.

For each aluminum nitride powder, the average grain size was 0.6 microns and the specific surface area was 3.4 m 2 /g. To the aluminum nitride (AlN) powder, 0.7 percent by weight of yttrium oxide was added, an acrylic binder and organic solvent were added, and mixing was performed with a ball mill for 24 hours to form slurries.
When the advantages of both CIA and ball milling are combined to manufacture black powder, the performance of the end product can reach or surpass commercial. While the CIA method - if properly executed - ensures a superior integration of potassium nitrate, the ball mill method is employed to intimately mix charcoal and sulphur.
A ball mill, which is a type of crusher, is a cylindrical device used to grind chemicals into a very fine powder to increase the surface area of pyrotechnic compositions and make the reactons take place faster. Black powder and other flammable materials require non-sparking lead antimony, brass, or bronze grinding media.
Used my homemade black powder in my TC black diamond express today with some boolits sent to me by someone on the site. The powder performed really well with both 450gr .505 and .245gr power belts. The recoil was a little lighter than commercial powder but it had a nice crack to it. Much less smoke than other powers that I have used with still a very …
Page 1 of 4 - Charcoal and black powder - posted in Newbie Questions: I need to know, just to make sure, does black powder need somekind of special charcoal, or can i just light up some wood matches and use that charcoal. Second question is, that can i use brayer, not ball mill to mix up black powder? Thanks!
Step 1: Ball mill each of the ingredients separately. Step 2: Mix in the proper ratio of sulfur and charcoal. Step 3: Add isopropyl alcohol to charcoal/sulfur and mix thoroughly. Step 4: Measure 1/4 cup (40 ml) of water for every 1/2 cup (100 grams) of Saltpeter aka potassium nitrate in an old pan. Add your potassium nitrate. Bring to a boil.

A continuous process of manufacturing black powder and black powder substitute using a twin screw extruder is disclosed. Guar gum mixed with the composition at a concentration in the range from 0.05% to 0.5%, by weight, dramatically reduced the friction in the dies and permitted extrusion of the powder at much lower water levels.

For powders, which can be defined as small-sized granular materials subject to cohesion and suspension in a gas, the definition of the angle of repose is frequently linked with the Hausner ratio or the tapped-to-bulk density ratio [], and the powders will flow at angles greater than the angle of repose [].The angle of repose can also indicate the cohesiveness of the …

Making black powder is more complex than simply mixing the three ingredients together. This is in fact called green powder or polverone which burns slowly and inefficiently leaving lots of un-burnt solids behind. Proper black powder is mixed thoroughly to a fine powder using a ball mill or with other non-sparking grinding media.

Grinding Theory: There are a lot of misconceptions about what goes on in a ball mill.
Have not made black powder since I was, oh, 12. I have a Harbor Freight tumbler with its two rubber chambers suitable for milling BP. (I don't use the small rubber chambers for brass cleaning as I built a larger chamber from 4" PVC that holds more and is easier to seal and open.) Some say "ball mill the BP ingredients using lead balls."
