ABSTRACT:
An agitator mill comprises a grinding receptacle and a rotarily drivable agitator arranged therein. A grinding-stock supply mouthes into the grinding chamber; a grinding-stock discharge leads out of the grinding chamber. The grinding chamber is at least partially filled with auxiliary grinding bodies. The grinding-stock discharge is embodied as a device for grinding stock suction and auxiliary-grinding-body separation, comprising a plunge pipe which dips into a bed of grinding stock and auxiliary grinding bodies and from which, above the grinding receptacle, discharges a suction pipe with a grinding-stock suction device.
