The invention relates to an arrangement in granulating mills including a cutter disposed for rotation in a granulate container (6), above which there is a collection hopper (9) for feeding the shaped pieces of preferably plastics material that are to be comminuted, and a high pressure air pump (17) for conveying ready comminuted granulate away from the container (6). The cutter is mounted for rotation in bearings (13) placed on a centrally disposed subframe (14), in turn pivotably mounted on a main pivot shaft (15) journalled in bearings on the main frame (4) of the mill (1). The cutter (5), hopper (9) and container (6) are hingedly, via pivot means (21, 22), and openably connected to each other, these components being pivotable about the shaft (15) via the central subframe (14) carrying the cutter (5). The line of action of the common centre of gravity of the pivotable components (5, 6, 9) extends through the shaft (15), and thus these are statically balanced about it. Accordingly, only minor force is required to pivot the components (5, 6, 9) into the opened state of the mill for service and/or cleaning in connection with changes in pigment/material. |
