Patent ID: 8414283

Claim:
A pelletizing apparatus for the pelletizing of plastics and/or polymers comprising: a diverter valve having at least one melt generator connection, a bypass position, at least two pelletizer connections and a valve gate for the selective connection of the melt generator connection to at least one of the pelletizer connections; a first pelletizing head and a second pelletizing head being connected to the at least two pelletizer connections, respectively, said first and second pelletizing heads having different throughput capacities; a melt generator for generating a melt having a variable melt volume flow being connected to the melt generator connection; a central control apparatus configured to switch the connection of the melt generator connection of the diverter valve between said first and second pelletizing heads in dependence on the melt volume flow of the melt generator; and a detection mechanism for detection of the melt volume flow directed into the diverter valve, said central control apparatus automatically switching over the diverter valve in dependence on a signal of the detection mechanism.
