Planetary ball mills often show shorter reaction times compared to mixer mills. This might be caused by the more frequent creation of new surface by the sheering motion as compared to the direct impact which rather compresses the powder present on the active surface. 23 It might also be the case that the higher energy input in planetary ball ...

This full hydrodynamic fluid film allows these bearings to support extremely heavy loads and operate at high rotational speeds. Surface speeds of 175 to 250 meters/second (30,000 to 50,000 feet/minute) are common. Temperatures are often limited by the lubricant used, as the lead and tin babbitt is capable of temperatures reaching 150°C (300°F).
