    For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, ,

    To load the mill jar optimally, fill it half full of a dense media such as 1/2inch lead balls. 50caliber muzzle loading bullets will work, but they are soft and will both wear down over time and leave lead dust in whatever it is you are milling. It's better to antimonyhardened 1/2inch diameter lead balls, made specifically for pyrotechnic ...

    If you’re making a custom fixture, a 1/8" flat end mill is your best friend. For 3D shapes, a 1/8" or 1/16" ball endmill produces the smoothest contours. For best results, keep a set of end mills specifically for HDPE and other plastics, and never use them to cut metal or PCBs. This will allow for increased milling speeds and a better finish.
