In such a ballmill 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 ballmill of this type has been described by R. Bloch and C. Rosetti in Chemiker Zeitung (1932), page 196.

That last equation shows that the vertical component of the force of tension is equal in magnitude, but opposite in direction, to the force of gravity. There isn't a normal force because normal force requires contact with a surface. In that second example, the ball on the string is just moving through the air.
