Ball milling questions for rockets - Rocketry - APC Forum

Ball milling questions for rockets - posted in Rocketry: I have several ball mills varying in size. I have come to use the largest which is 3 gallon. I have only enough lead for the 3 gallon which has been exclusively used for milling BP. My question is would it be safe to wash the media to use in a smaller 1 gallon setup to mill sodium or potassium benzoate and then wash again before ball ...
