How does centrifugal force work?
$begingroup$ @Josh: the point I meant to make is that if you draw a force diagram in the rotating reference frame, there is a real centrifugal force that does go on a force diagram.With respect to Lagerbaer's example, in the rotating reference frame, the bucket does fly away along the line connecting you and the center. In intro physics …

ATTRITORS AND BALL MILLS HOW THEY WORK
IV. BALL MILLS Ball mills are one of the more common mills and use a closed cylindrical container that is rotated horizontally on its axis so that the media cascades. A typical ball mill has an L/D ratio of 1.5:1. Ball mills are filled with spheres or other shapes made of steel or ceramics; or with pebbles made of flint (or of an ore being ground).

Centrifugal Casting – EngineeringTechnology
Centrifugal casting is a metal casting process in which molten metal is poured into a rotating mold and solidifies under the influence of centrifugal force. The centrifugal force helps to distribute the molten metal evenly and eliminate any air pockets or voids that might be present, resulting in a uniform and dense casting. There are two main ...
