Abstract
A device for granulating thin-walled plastic material into plastic granulated material. The device is composed of a rotating tool which is arranged closely above the bottom of a container. The tool produces frictional heat when moved relative to the material in the container. More specifically, the tool has at least two rotatable shafts, both of which are equipped with beaters thereon. The peripheral circles described by the outer ends of the beaters come close together or are overlapped, and, when in the overlapped condition, are vertically offset from one another.
