Agitator mill comprising basket comprising slits

An agitator mill comprising a grinding chamber including grinding bodies and an agitator shaft, which revolves therein about a horizontal agitator shaft axis, which supports several grinding members, which are connected to it in a rotationally fixed manner and which are spaced apart from one another in the direction of the horizontal axis, preferably in the shape of grinding disks, which move the grinding bodies, whereby, on the outlet side, the agitator shaft has a basket, which is preferably studded with grinding members on its outer circumference and which overlaps the split tube-supporting outlet, whereby a separation chamber is formed between the inner surface of the basket and the split tube-supporting outlet, wherein the basket has slits for returning grinding bodies from the separation chamber into the grinding chamber, which slits lead into the free front surface of the basket, which faces away from the grinding chamber, whereby the slits change their expansion and/or shape at least regionally.
