Abstract: The invention relates to a rotary tablet press and method of operation. The rotary tablet press includes a rotor that is rotatably driven that is coupled to a die plate with holes. Upper and lower punches are assigned to the holes and rotate synchronously with the die plate. A pressing apparatus presses the punches into the holes to press the filling material added to the holes. An ejector apparatus ejects the tablets pressed into the holes. A control apparatus automatically changes the rotary speed of one or more components in response to changes to components of the rotary tablet press and process components upstream or downstream of the rotary tablet press.
