Feed-mixing device comprising a container with a side wall having a dispensing opening which can be closed off with a slide, in front of which a removing device is placed which, for example, comprises a roller with teeth. When the roller rotates, the teeth extend inside the side wall. On a first peripheral section of the roller, the teeth are placed in such a manner that they do not extend inside the side wall. Thus, the slide can be positioned in such a manner that it runs in a fluent and continuous manner with respect to the side wall, while the assembly still forms a compact arrangement.
