planetary ball mill. Planetary mills with a single grinding station require a counterweight for balancing purposes. In the Ball Mill PM 100 this counterweight can be adjusted on an inclined guide rail. In this way the different heights of the centers of gravity of differentlysized grinding jars can be compensated in order to avoid disturbing
