Abstract:
A rotary tablet forming press, comprising:a base frame;a rotor with a drive;a pressure roller unit with punch elements engaging with said rotor and having a punch engagement frequency based on a speed of rotation of said rotor;elastic mounts on said base frame; anda base plate mounted on said elastic mounts, and on a side of said elastic mounts opposite said base frame, said base plate mounting said rotor with said drive and said pressure roller unit, said elastic mounts having a rigidity, said rigidity and a mass consisting of said base plate with said rotor and said drive and said pressure roller unit are coordinated with one another such that a natural frequency of a resulting vibration system is lower in all six possible degrees of freedom than a lowest punch engagement frequency occurring at a lowest speed of rotation, which is an excitation frequency.
