If one mills a white powder like potassium nitrate with lead media, the powder will come out of the mill gray. That means there is some lead in the chemical, which will be in the smoke that results from it being burned. That presents a danger of lead poisoning if one breathes a lot of that smoke.

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints. Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls,flint pebbles ...

Ball mill the potassium nitrate, charcoal and sulfur for at least two hours. Screen the aluminium into the meal using the screen method until the mixture is homogeneous. The meal may be used as is, but it is preferable to moisten with a 25% solution of alcohol, knead and force through a 20 mesh screen to granulate it.

Ball mill. 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.

The ball mill machine was then operated at a speed of 300 rpm for 12 h and the rotation direction altered every 3 h. The resultant ball-milled biochars were labeled with BM, namely, BMHC450, BMHC600, BMBG450, and BMBG600. The N-doped biochar was prepared by ball milling 1.8 g biochar samples with 18 mL ammonium hydroxide (29%).

A ball mill or mortar and pestle is good, but the job can be done much faster using a coffee grinder (the finer the powder is, the faster it will burn). Grinding an oxidizer (Potassium Nitrate) together with fuel (Charcoal) with metal blades is a bad idea as it may combust. If you grind chemicals in coffee grinder be sure to have one for fuels ...

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.

Put the potassium nitrate in your ball mill, and mill it for 3 hours. You should have a very fine white/greyish powder. 4. Now mix the charcoal/sulfur mix with the potassium nitrate. Don't bother to mix it very thoroughly, since that will happen in the mill soon enough. To this mixture, add 6% of water.

My modified ball mill using brass balls - posted in Pyrotechnics: Hello forum. Sometimes ago I ordered this ballmill from Pyrocreations: It has an internal barrell diameter of 103mm and a capacity of 0.8l. The working voltage is 120V, but since I live in Italy, I was forced to buy a transformer 120 -> 220V The first issue of this very cheap ballmill was the rotation: only …

To ball mill or not to ball mill..... - posted in Pyrotechnics: That is my question....I have been gathering different star formulas to try this spring. I noticed that some include basic instruction, but most do not. I know that if the formula includes dextrin or similar (and it does not have Mg) then I can wet with water and alcohol and start rolling.

mill is rotated at high speed for up to 48 hours or longer. The result is a very finely powdered charcoal/sulfur mixture. (Note: for reasons which should be very obvious, the Potassium Nitrate is not mixed in with the fuel during the milling stage, unless you want to be picking bits of your ball mill out of the walls of your factory.)

Potassium nitrate is a white powder or long needle-like crystals manufactured by Haifa with the chemical name KNO3. This is very high quality at 99.4-99.7% purity and works perfectly for all applications. This item is granulated and has the consistency of table salt. The most famous use of potassium nitrate is probably as the oxidizer in black ...

A laboratory planetary ball mill (Pulverisette-7, Fritsch, Germany) equipped with two zirconia grinding pots (inner volume of each pot: 45 mL) was used. After that 1.5 g smithsonite sample, Pb chloride or Pb nitrate, and 10 mL deionized water were added to each pot with seven zirconia balls (diameter of each ball: 15 mm), the mill was set to ...

Milling the charcoal with the ball mill will get those particles very small. We could stop there and mill the potassium nitrate in with the charcoal (this is the common way most rocket enthusiasts make black powder now). Potassium nitrate dissolves in water though, which gives us another option.

The procedure was duplicated for each ceramic phase in order to perform two different milling conditions. The mixtures were separately processed in a horizontal rotary ball mill (Simoloyer CM01; Zoz , Germany) in air, using Fe 500 grade steel balls (diameter of 4.7 mm) with a ball-to-powder ratio (BPR) of 100: 6.

As the ball mill rotates, the lead balls will crush the chemicals together, forcing some of the potassium nitrate into the pores of the charcoal and sulfur. At the same time, the entire mass will be reduced to a super fine powder. The longer the ball mill runs, the stronger the black powder will be.
