Abstract: 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.

Abstract: 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.

Abstract: 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.
