ABSTRACT:
A planetary ball mill in which a plurality of mill pots revolve by receiving a rotational force from a main shaft, while rotating on their own axes. A feed is continuously supplied to the mill pots so that ground particles are discharged out of the mill pots utilizing air flow. A partition for dividing a grinding chamber from a discharge pipe is disposed on the discharge side of the chamber of each mill pot so as to permit only the feed already ground to pass through. The feed having passed through the partition is collected by way of a discharge chute not rotating but surrounding a discharge pipe which rotates relative to the discharge chute to generate a negative pressure which assists the discharge of ground feed from each mill pot.
