Patent number: 10981179Abstract: An accumulation device that is operable in a feeding arrangement of a granulator, for accumulating flat material to be granulated, includes a first guiding device and a second guiding device. The accumulation device further includes a rotational shaft arranged to connect the accumulation device to the feeding arrangement. The first and the second guiding device are fixedly arranged in relation to each other so that when the accumulation device is rotated around its rotational shaft, the first guiding device as well as the second guiding device is rotated around the rotational shaft. A feeding arrangement and a granulator including such an accumulator device are also provided.Type: GrantFiled: April 2, 2019Date of Patent: April 20, 2021Assignee: Rapid Granulator ABInventors: Kurt Sjöberg, Magnus Blom, Ernad Jugo

Publication number: 20210086191Abstract: Disclosed is an accumulation device (150) operable in a feeding arrangement (110) of a granulator, for accumulating substantially flat material to be granulated. The accumulation device (150) comprises a first guiding device (152) and a second guiding device (154). The accumulation device (150) further comprises a rotational shaft (156) arranged to connect the accumulation device (150) to the feeding arrangement (110). The first and the second guiding device (152, 154) are fixedly arranged in relation to each other so that when the accumulation device (150) is rotated around its rotational shaft, the first guiding device (152) as well as the second guiding device (154) is rotated around the rotational shaft (156). Disclosed are further a feeding arrangement (110) and a granulator comprising such an accumulator device (150).Type: ApplicationFiled: April 2, 2019Publication date: March 25, 2021Applicant: Rapid Granulator ABInventors: Kurt SJÖBERG, Magnus BLOM, Ernad JUGO

Patent number: 8464973Abstract: A granulator mill has a mill housing with a fixed section and an openable hatch, which is pivotally connected to the fixed section by the intermediary of a first pivot with a vertical pivot axis. The openable hatch has a first part and a second part, which are pivotally connected to one another by the intermediary of a second pivot with a vertical pivot axis.Type: GrantFiled: June 30, 2009Date of Patent: June 18, 2013Assignee: Rapid Granulator ABInventors: Henrik Karlsson, Kurt Sjöberg, Ulf Henning

Patent number: 8353471Abstract: A method of producing a foundation bed (1) for a granulator mill includes the steps that the foundation bed is cast from a plastic- or concrete based casting material in a mold (13) manufactured from thin sheet metal, the mold being given surfaces (16) for cooperation with a granulator mill housing (2) with high precision. In order to avoid after-treatment of the surfaces (16) of the mold intended for cooperation with the granulator mill housing, these surfaces are clamped during the casting process against a common, configurationally stable clamping member.Type: GrantFiled: December 26, 2008Date of Patent: January 15, 2013Assignee: Rapid Granulator ABInventors: Henrik Karlsson, Kurt Sjöberg, Ulf Henning, Björn Pettersson

Publication number: 20110089279Abstract: A granulator mill housing for a granulator mill has a rotor, provided with knives, journalled therein, and seats against which fixed knives may be fixedly clamped by means of screws and guide bars. At a lower seat, there is a stand on which a guide bar is placeable in a preparatory position. The side of the guide bar, intended for cooperation with the knife is turned upwards. Pivoting of the guide bar and the knife will move the knife into abutment with the seat. On mounting of a knife against a seat in a granulator mill housing, the knife and a guide bar are screwed in position against the seat. First the guide bar is placed on a stand, whereafter the knife is placed on the guide bar, and the guide bar and the knife are pivoted together to a mounting position with the knife in abutment against the seat where screws are mounted.Type: ApplicationFiled: June 30, 2009Publication date: April 21, 2011Applicant: RAPID GRANULATOR ABInventors: Henrik Karlsson, Kurt Sjöberg, Ulf Henning
