Agitator mill

摘要

An agitator mill comprises a grinding receptacle and an agitator unit disposed in the latter and having an agitator shaft. The agitator shaft is hollow, this grinding-stock/auxiliary-grinding-body return chamber being connected with the grinding chamber at one end of the agitator shaft. At the other end of the agitator shaft, the return chamber opens into a cage-type section of the agitator shaft, an auxiliary-grinding-body retaining device likewise projecting into this section.
