A device for granulating plastic strands includes an extruder having a nozzle plate with boreholes arranged in front of a manifold and a starting valve connected thereto, and a cutting device with a knife head arranged centrally in a receiving housing wherein the cutting knives of the knife head rotate in the region of emergence of plastic strands which are acted on radially by a coolant. The cooling is accomplished by providing a cutting plate with cooling boreholes aligned axially with the nozzle boreholes of the nozzle plate. These cooling boreholes extend up to an insulating layer except for a recess which is connected to a coolant feedline for releasing at least one flow cross section of coolant which corresponds to the cooling boreholes. |
