초록

An apparatus for granulating hot cut, in particular thermoplastic resin material, the material strands melted by an extruder being knocked off into granule pellets in a granulating housing by rotating knives disposed on a shaft driven by way of a motor, the granule pellets being picked up by a cooling medium flowing in the granulating housing, cooled and discharged out of the granulating housing, characterized in that a flow opening establishing a continuous fluid connection between the inside of the granulating housing and the outside environment is des...
