Abstract

The invention relates to an agitator mill which, on the outlet side of the grinding space, has both a static separating arrangement and a dynamic separating arrangement. These two separating arrangements complement one another ideally as, in the start-up phase, in particular the dynamic separating arrangement ensures a fault-free start while, in running operation, the static separating arrangement enlarges the overall effective passage opening in a desirable manner and thus leads to low pressure in the mill. The agitator mill according to the invention is thus characterised by high operational safety, low maintenance expenditure, low wear and universal applicability. <IMAGE>
