<p>A sub-water granulating device for granulating thermoplastic synthetic plastics materials is operatively combined with the nozzle plate of a screw extruder. The device comprises a rotary cutting tool head which is enclosed by a dome or hood. Flushing water is fed into the dome and discharged therefrom and the flow of water is directed to clean the cutting tools and to carry out granules cut by the tools thereby preventing the formation of lumps of granules and adhesion thereof to the nozzle plate.</p> |
