ABSTRACT:
In an agitating mill for producing the objective fine powder, the agitating medium having an average particle diameter of no more than 0.6 mm is charged in an annular gap between the external side wall of the agitator and the internal side wall of the milling vessel. Thereby the agitator can be rotated at a peripheral speed of no less than 30 m/s, and it results in a high grinding rate and reduced amount of impurity which means worn-out grinding media included in the objective fine powder.
