A feeding device for feeding left-over material (2) to be disintegrated, comprising a rotating feeding roll (9) and a catcher (12) arranged substantially in parallel with the feeding roll (9). The catcher (12) is yielding and non-locking in order to stay in contact with the feeding roll (9) and to prevent the return of disintegrated material past the feeding roll (9). The catcher (12) is divided into sections (12a, 12b, 12c) being individually yielding and non-locking. In a particular embodiment, the spring features are adjustable.

A granulator mill housing for a granulator mill has a rotor (4), provided with knives, journalled therein, and seats (8) against which fixed knives (7) may be fixedly clamped by means of screws (18) and guide bars (9). At a lower seat, there is a stand (10) on which a guide bar (9) is placeable in a preparatory position. The side (13) of the guide bar, intended for cooperation with the knife (7) is turned upwards. Pivoting of the guide bar and the knife will move the knife into abutment with the seat (8). On mounting of a knife (7) against a seat (8) in a granulator mill housing, the knife and a guide bar (9) are screwed in position against the seat (8). First the guide bar (9) is placed on a stand (10), 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 (8) where screws (19) are mounted.

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).

A granulator mill has a mill housing (1,2,3) which has an openable part (2) and a fixed part (1), and an infeed hopper (4). In the fixed part (1), there is a rotor with a number of blades (13) which co-operate with fixed blades (14) in the mill housing. In the openable part (2), there is a discharge section (16) which is discrete from the interior of the mill housing by means of a grid ( 15) which surrounds approximately 160° of the rotor and extends in beneath it. The fixed part (1) and the openable part (2) are connected to one another by the intermediary of a pivot device with a vertical pivot axis (9). The end of the openable part (2) facing away from the pivot axis (9) is fixedly lockable in the fixed part ( 1) at the journal box (20) of the rotor and is centred there by a guide surface (21) at the journal box and a guide surface (31) on the openable part (2). The openable part (2) is thus horizontally pivotal and may be opened manually. The infeed hopper (4) is vertically pivotal about a horizontal axis and opened by means of a motor. The infeed hopper (4) and the openable part (2) have mutually engaging locking means which lock the infeed hopper in the closed position when the openable part (2) is closed.
摘要:
A knife assembly for a size reduction machine, such as a shredder or a granulator (1) includes a rotor (4), wherein a knife (10) is fixed on a seat (13) and arranged for cooperation with a number of knives (9) on the rotor (4). The fixed knife (10) is planar with a general plane of extension. The fixed knife (10) is held by at least two knife holders (15), which are arranged to displace the knife (10) in a direction which is approximately parallel with its plane of extension.
