Lei Yang, in Nanotechnology-Enhanced Orthopedic Materials, 2015. 2.1.2 High-energy ball milling. High-energy ball milling is a mechanical deformation process that is frequently used for producing nanocrystalline metals or alloys in powder form. This technique belongs to the comminution or attrition approach introduced in Chapter 1.In the high-energy ball milling process, coarse-grained ...

As far as ball mill safety goes, the motor should be completely separated from the milling area, so that no powder can get to the motor. I also barricade my ball mill with a thick inner layer of Styro surrounded by an outer layer of concrete blocks. The least you can do is prepare for a potential accident.

Gunpowder or black powder is of great historical importance in chemistry. Although it can explode, its principal use is as a propellant. Gunpowder was invented by Chinese alchemists in the 9th century. Originally, it was made by mixing elemental sulfur, charcoal, and saltpeter (potassium nitrate).The charcoal traditionally came from the willow tree, but grapevine, hazel, elder, …

Sometime in the 1840's there were various attempts to use a smokeless powder, but they were unstable and dangerous. For a short period of time, there were various types of semi-smokeless and brown powders, neither of which lasted very long. Black powder has been around for hundreds of years.

Use a mortar and pestle to grind each ingredient into a fine powder. Grind each ingredient separately, cleaning the mortar and pestle in between uses. You can use a ball mill to grind the components if you're planning on making a lot of gunpowder. A ball mill is used to both grind and mix powders safely. 2.

Depending on the powder and percentage of case fill, temperature and angle of the cartridge at discharge, a significant reduction in powder weights can create a very dangerous situation. When powder does completely cover the primer, there is a chance for delayed ignition/detonation.

N.V. Kosova, in High-Energy Ball Milling, 2010. 14.2.2 Synthesis of LiNi 1 − X − Y Co X Mn Y O 2. Cathode materials based on solid solutions of LiNi 1 − y Co y O 2 are less expensive than LiCoO 2 and show a larger discharge capacity at 4 V. Their discharge curves have a sloping form.

Hodgdon Hybrid 100V is an example of this type of design. Ball propellants have several advantages over stick propellants. The first is that they flow easily and meter very uniformly through a powder measure. The second is they have higher bulk density than stick types; you can get more charge weight in the case.
