ABSTRACT:
An agitator mill comprises an annular cylindrical exterior grinding chamber which is defined by an inner wall of a grinding receptacle and an outer wall of a rotor; and an interior grinding chamber which is defined by an inner wall of the rotor and an outer casing of an interior stator. The grinding chambers are interconnected by a deflection chamber. A grinding-stock supply area, which is upstream of the exterior grinding chamber, and a separator device, which is disposed approximately on the same side of the grinding receptacle, serving for grinding-stock discharge, are interconnected by auxiliary-grinding-body return conduits. These conduits are arranged in an independent auxiliary-grinding-body return module and are open towards a front of the module.
