During the operation of the planetary ball mill, it generates an extremely high level of impact energy between the grinding balls and the grinding jars, allowing it to complete the sample grinding in a very short duration. The fundamental principle of the planetary ball mill hinges on the relative rotation of the sun wheel and the grinding jar.
