For instance, if your jar had in inside diameter of 90 mm and your milling media was mm diameter lead balls, the optimum rotation would be 98 RPM. Optimum RPM= .65 x Critical speed (cascading action of the media stops) Critical speed = /sqrt (Jar Media ) with dimensions in inches.
Making molds for the milling media.
