Abstract:
1. A rotary press with a housing and a rotor with dies and upper and lower press punches, guide cams for the press punches, pressure rollers, and a filling device in the housing, and a feed for powdered press material to the filling device, characterized in that to the feed ( 24 ) or the filling device ( 22 ) is assigned a microwave resonator for measuring the density and/or the size of the granulate of the powder including an analysis unit ( 46 ) receiving the measured values from the microwave resonator, and in that a control device changes the rotation speed of the rotor and/or the rotational speed of the filling device and/or the adjustment for a dosing curve and/or adjustment for the pressure rollers if an actual value representing a measured value of the microwave resonator differs from a predetermined desired value.
