  • Patent number: 8708551
    Abstract: A continuous granulator comprises a longitudinal granulation chamber having a first end with an inlet for powder material and a binder feed port and a second end with an outlet for granulated product. The granulation chamber comprises at least two parallel rotary shafts provided with granulating elements and forming an angle of from 0 to 70 degrees with the vertical. Each granulating element on a shaft comprises at least one lobe having limited extent in the circumferential direction of the shaft and interleaving with a lobe of a granulating element on another shaft. A plurality of such separate granulating elements are distributed from the inlet to the outlet, and successive granulating elements on a shaft are mutually angled.

  • Patent number: 8277707
    Abstract: A rotary tablet press comprises a housing and a rotary die table having dies arranged circumferentially. Each die is associated with a punch having an end receivable in the die and being arranged for compression of a powder or granular material in the die by reciprocation of the punch by rotation of the die table. The rotary tablet press comprises a feeding device and a tablet discharge device. Each die opening and its corresponding punch end are enclosed in a compression chamber comprising a dust extraction nozzle. The compression chamber communicates with the surroundings of the tablet press through a non-return valve arranged to prevent outflow from the compression chamber to the surroundings of the tablet press.
