Abstract

A closed agitator mill for grinding and mixing solids in liquids has a grinding space partially filled with auxiliary grinding elements, in which an agitator mechanism that can be driven at high speed is located; the agitator mechanism comprises an agitator shaft and agitator tools attached to it and generates a flow of grinding stock and auxiliary grinding bodies. At least one tubular screen cartridge, which is interchangeable from outside, is disposed before a ground stock outlet from the grinding space. The screen cartridge protrudes into the space between the agitator shaft and the wall of the grinding space and serves to separate the auxiliary grinding elements from the grinding stock. In order to attain satisfactory, substantially wear-free separation of the grinding stock and the auxiliary grinding elements even when the material to be ground is highly viscous and/or with high throughput, the screen cartridge has a cross section the extension of which is longer, in the flow direction of the flow of grinding stock and auxiliary grinding elements in the grinding space, than at right angles to the flow direction.
