A device is provided which determines the end of the processsing time for hardening masses, in particular dental molding masses. The device comprises a display unit and a sensor unit which record the change in at least one of the rheological properties of the mass. A method that can be used with such a device is described.

Device for determining the end of the processing time for hardening masses

The invention relates to a dynamic mixer, comprising a housing () and an inner body () which can be rotated about a common axis in relation to each other and which form a mixing chamber (); a back shut-off element () which delimits the mixing chamber () and which has inlet openings () for guiding in the components to be mixed, a front outlet () for delivering the mixture and a drive element () which is located on the rotatable part of the mixer. The inner body () is connected to the shut-off element () and forms the stator of the mixer, while the housing () is provided with the drive () and forms the rotor of the mixer.
