ball milling bp ingredients separately how long?
WEBAug 25, 2013 · Never ever ball mill potassium perchlorate and aluminum together in a ball mill. There are only a few mixes of components that can be mill together. Always use saftey first when using a ball mill. Black Powder can only be milled if using nonsparking grinding media. Be safe.....Pat. Edited August 26, 2013 by patsroom
