Abstract: The invention relates to an agitator mill which has both a static separating arrangement and a dynamic separating arrangement on the outlet side of the grinding chamber. These two separating arrangements complement one another in an ideal manner, since in the starting phase in particular the dynamic separating arrangement ensures a trouble-free start, whilst during operation the static separating arrangement enlarges the total effective opening in a desired manner and thus leads to a low pressure in the mill. Thus the agitator mill according to the invention is distinguished by a high level of reliability, low maintenance costs, low wear and universal applicability.
