Abstract
A nozzle arrangement for a granulator has a nozzle body with an inlet side as well as an outlet side, a nozzle plate with nozzle holes arranged on the outlet side for forming melt strands, and flow channels formed in the nozzle body and connected to the inlet side and the outlet side in a fluid-conducting manner for supplying a melt flow to a nozzle plate. An annular connection channel connects a plurality of flow channels in a fluid-conducting manner. A method for separating a melt flow into melt strands is also described.
Claims22
A nozzle arrangement for a granulator, the nozzle arrangement comprising:
- a nozzle body with an inlet side and an outlet side;
- a nozzle plate with nozzle holes to form melt strands, said nozzle plate being arranged on the outlet side of the nozzle body,
- wherein a plurality of flow channels are formed in the nozzle body and extend from the inlet side and to the outlet side in a fluid-conducting manner for supplying melt flow to the nozzle plate;
- and
- at least one annular connection channel in fluid communication with both a flow channel of the plurality of flow channels of the nozzle body and the nozzle holes of the nozzle plate.
