Agitator ball mill having wear prevention

An agitator mill having a vertically arranged container in which there is arranged an agitator which is rotatable about a vertical axis, and at least one wear prevention element which can be mounted to the container inside wall by means of a fixing system, wherein the fixing system comprises a fixing pin and a fixing opening which are arranged on the container inside wall and/or the rear side of the wear prevention element in such a way that the wear prevention element can be fixed to the container wall by a movement of the wear prevention element in a direction which includes an angle α>0° with the vertical axis of the rotatable agitator, by the fixing pin being guided into the fixing opening, the agitator ball mill characterised in that there is provided an elastic element which is arranged at the fixing opening and at least partially closes same so that the fixing pin can be removed from the fixing opening only by the application of a release force greater than the return force of the elastic element.
