Grinding Down to the Nanoscale with Planetary Ball Mills
Apr 03, 2013 · Planetary ball mills are the most commonly used ball mills in laboratories for preparing samples ranging from soft to hard to brittle and fibrous materials. The mill derives its name from the unique kinematics wherein the grinding bowls are mounted on a rotating "sun" disk that rotate in the opposite direction around the disk centre.
