Abstract
A device (1) for comminuting or grinding including a container (2) for receiving the material to be ground and a tool (5) which rotates in the container (2) during processing, and a drive for said tool (5). The container (2) having the tool (5) can be detachably coupled to the drive, which is to say that the container (2) having the tool (5) does not have to be cleaned after a grinding operation but can be replaced by a new such container (2). For this purpose, the tool (5) located in the container (2) can be rotated loosely when in the position of being detached or uncoupled from the drive or before a corresponding coupling operation and, when in the working position, is rotationally fixedly connected to the drive and centered by the coupling.
