Page 16 of 17 Ball Milling FAQ posted in Newbie Questions: To answer a few questions: The container is PE plastic. Brass is always polished dry. The bowl is designed to slowly turn over the media. I have a couple of blade grinders and they work well, but still dont produce a fully powdered, talc like product. This vibratory does it completely and rather quickly.

If one is milling only individual chemicals like charcoal or potassium nitrate, then any of these media are safe for crushing it. It is when one gets into milling mixed compositions like black powder that the dangers arise. We simply don't want sparks generated in the mill jar during that process for obvious reasons.

In coating technology, many coating methods have been developed to enhance metal's resistance to corrosion. This study demonstrated the use of a simple, easy, and economical manual thermal flame spray method to create an anticorrosion coating layer composed of ballmilled wood charcoal (a readilyavailable source of carbon) and titanium dioxide (TiO2).

Herein, a series of novel biochar materials (BPBCs) were prepared by combined ball milling and phosphorus (P)loading. The optimized BPBC were fabricated in the basis of Cd and Pb adsorption capacities of the biochar, with pyrolysis at 700 °C, ball milling for 12 h and the addition of 5% red P (BPBC700).

You could use the CIAMethod. That means you mill the charcoal and the sulfur without the KNO 3. Than you dissolve your Nitrate in boiling water, add the milled C and S and precipitate the KNO 3 with ice cold ethanol. This process makes a very fast powder, and you don´ t have to mill any explosive composition, however it is labourintensive.
