Abstract: An agitator mill including a grinding chamber containing grinding bodies and an agitator shaft, which revolves therein around a horizontal axis and which supports several grinding disks, which are connected thereto and which are spaced apart from one another in the direction of the horizontal axis and which move the grinding bodies, wherein grinding disks preferably in each case have slits or apertures, wherein adjacent grinding disks are arranged on the agitator shaft so that the ratio of the grinding chamber length to the radial grinding chamber height is greater than or equal to 2:3, and that the radial distance between the outer jacket surface of the grinding disks and the inner wall of the grinding container limiting the grinding chamber is more than 20% of the radial grinding chamber height.

Abstract: A stirring mill, including a horizontally arranged milling vessel and a stirring shaft which is arranged therein so that it can be rotationally driven are provided. The stirring shaft has a first stirring shaft section adjacent to an inlet for material to be ground, which has a smaller diameter D24, and a second stirring shaft section adjacent to an outlet for material to be ground, which has a larger diameter D25 and in which a separating device is formed. Bypass channels leading into the separating device are formed in the first stirring shaft section.

Abstract: A cleaning device including a housing which can be arranged on a feed line for cleaning fluid is disclosed. The housing includes an exit opening for the cleaning fluid, wherein a nozzle head rotatable about a first rotary axis is arranged in the region of the exit opening. A distributing device rotating about a second rotary axis different from the first rotary axis and having at least one blade element or at least one pendulum element is arranged on the rotatable nozzle head. The invention also describes a product-processing plant with at least one cleaning device for cleaning a product tank.
