Abstract: A method for evaluating a wear condition of a component of a rotary press includes providing the rotary press which includes the component. Values of at least one of: (i) ejection forces acting on the ejector cam during operation of the rotary press; and (ii) vibration frequencies occurring during operation of the rotary press are measured. The wear condition of the component of the rotary press is evaluated based on the measured value.

Abstract: A method of manufacturing a rotary press that assesses a wear state of pressing punches includes structuring the rotor to comprise an upper punch guide for upper pressing punches, a lower punch guide for lower pressing punches, and a die plate defining a plurality of cavities. A filling apparatus is structured to deliver a powder material into the plurality of cavities. A pressure apparatus includes an upper pressure roller that interacts with the upper press punches and a lower pressure roller that interacts with the lower pressing punches. At least one pressing force sensor is structured to measure pressing force progressions during the pressing of the powder material. An evaluation apparatus is structured to perform a state analysis of the measured pressing force progressions and individually assesses the wear state of at least one of the upper pressing punches and the lower pressing punches based on the state analysis.
