Movement Centrifugal Ball Mill

Movement Centrifugal Ball Mill

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.
