  • Patent number: 12759252
    Abstract: A method for test pressing pellets in a rotary press, wherein the method includes the following steps: a punch pair of an upper and lower pressing punch assigned to a receptacle of the die plate is brought into a dosing position in which the upper pressing punch is moved upward out of the receptacle and the lower pressing punch is located partially in the receptacle, such that the lower pressing punch presets a maximum filling height of material to be compressed in the receptacle, material to be compressed is filled into the receptacles, the pressing units of the pressing apparatus are moved toward one another such that an expected web height of a pellet to be manufactured in the test pressing is reached before the punch pair exceeds the place of the smallest distance between the pressing units during a rotation of the rotor, the rotor is put into rotary motion such that the punch pair for compressing into a pellet the material filled into the receptacle comes into contact with the pressing units, wherein the

  • Publication number: 20250121575
    Abstract: A method for test pressing pellets in a rotary press includes depositing material to be pressed into one of the plurality of receptacles of a die plate. The upper and a lower press punch are moved such that the upper press punch is positioned in an impact area of an upper test pressing tool of a test pressing apparatus of the rotary press. The lower press punch is positioned in an impact area of a lower test pressing tool of the test pressing apparatus. The upper and the lower test pressing tools are advanced towards each other via a test pressing drive of the test pressing apparatus so that the upper press punch and the lower press punch are driven towards each other in the one of the plurality of receptacles by the upper and lower test pressing tools to press the material in the receptacle into a test pellet.
