Centrifugal ball mill BLOCH; RUDOLF MOSHE

In such a ball-mill centrifugal forces are used, and a substantial improvement in performance of the mill can be achieved. The planetary movement is actuated by means of transmission belts or piston arrangements. A ball-mill of this type has been described by R. Bloch and C. Rosetti in Chemiker Zeitung (1932), page 196.

Centrifugal force Wikipedia

The concept of centrifugal force can be applied in rotating devices, such as centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves, when they are analyzed in a rotating coordinate system.The term has sometimes also been used for the reactive centrifugal force that may be viewed as a reaction to a

centripetal force Throwing a ball in a rotating space

Suppose the ball is shot "upward" (i.e. a force is exerted in the radial direction) from a point on the floor. From the perspective of an external inertial observer, it will indeed travel in a straight line, in the direction of the velocity vector at the time it left the floor, a combination of the tangential velocity from the rotation and the radial velocity from the force that shot it "up".
