Answer (1 of 2): You can't make black powder without grinding and milling - if you just mix the dry ingredients, all you get is a disappointingly slow fizzle. Commercial powder makers use edge mills that generally run 12 hours or more on each batch, but that's out of the question for a home maker...
If you haven't gotten one yet, then get a ball mill or make one. Look up ball mills, or rock tumblers, on the web - get a cheap one from Harborfreight.com - don't buy one on eBay or from other dealers until you do a price compare - there is a small ball mill from China that sells from $19 (Harbor Freight on sale) to about $80 at other sites ...

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, and stainless steel balls.

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 coating, or slurry containing 20–40% water by weight.
1- Physical cleaning: in this route, cleaning is achieved by mechanical effect obtained by milling a hard material that abrades the undesired materials. 2- Chemical route: in this route the balls ...
In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al .[ 19, 20 ] found a scale-up factor for the Isamill of exactly 1, while Gao et al .[ 8 ] imply that the scale-up factor for SMDs is 1.25.
The ball-mill-based mechanochemical activation of metallic copper powder facilitates solvent-free alkyne-azide click reactions (CuAAC). All parameters that affect reaction rate (i.e., milling time, revolutions/min, size and milling ball number) have been optimized. This new, efficient, facile and eco-friendly procedure has been tested on a number of different substrates and in all cases ...
Cleaning and Storing of Ball Mill Charge after the Bond Work Index Procedure is done: Add about 500 g of silica sand into the mill containing the ball charge. Seal the mill. Rotate for 20 revolutions to clean. Empty the mill charge and sand into the ball try once grinding is complete. Clean out the mill using a brush. Put the lid on the mill.
A ball nose end mill, also known as a spherical end mill or ball end mill, has a semisphere at the tool end. Ball nose end mills are used on workpieces with complex surfaces. Choosing flat end mill vs. a ball end mill will determine the characteristics of the tooling marks (or lack thereof) on your model.

Ball Nose End Mills. Ball nose mills have a radius at the bottom which makes for a nicer surface finish in your workpiece, meaning less work for you as the piece won't need to be finished any further. They are used for contour milling, shallow slotting, pocketing and contouring applications.
A mill is designed to work well within its elastic deformation stress range while the work-piece is in its plastic deformation stress range. The yield stress of C12 bronze is 18,000 psi. The area undergoing deformation is most of the contact area between the rollers and the sheet multiplied by the width of the sheet.
Ratio of work indices. If the rod mill (and crushing work index, to a lesser extent) are higher than the ball mill work index, then the circuit will probably require pebble crushing to operate efficiently. Desired transfer sizes. The transfer sizes displayed by the software are an instruction, and not a prediction.
The ball mill work index laboratory test is conducted by grinding an ore sample prepared to passing 3.36 mm (6 mesh) to product size in the range of 45-150 µm (325-100 mesh), thus determining the ball mill work index (Wi B or BWi). The work index calculations across a narrow size range are conducted using the appropriate laboratory work ...

Autogenous Mills operate, mechanically, similar to the ball mill. They differ in the media they use to break or grind the ore. Autogenous Mills use large particles of ore instead of steel or other balls for grinding media. Autogenous mills use large pieces of ore as grinding media. The grinding is facilitated in autogenous mills by attrition ...
