Mill finish aluminum refers to the original, unpolished state of the metal that has not been treated or finished in any way. This form of the metal is largely untouched, with the surface often appearing somewhat dull. Mill finish aluminum has not undergone any further processing after being produced from raw aluminum through an extrusion process.

Posted June 20, 2017. 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. I know ball milling is the most common for large quantities.

Mills are available with a wide-range of screen and impeller tooling, helping to achieve the various required final particle sizes and throughputs. Conical mills are typically suitable for size reduction down to approximately 150 microns (80 mesh) and generate minimal heat. They are suitable for both dry and wet milling applications.
