UnderWater Pelletizers are used for pelletizing different types of polymers but especially engineered for sticky plastics which have high melt flow index.
Plastic melt coming from the extruder passes through the die plate, immediately cut by the rotating blades. As water comes in contact with plastic directly at the die plate, UnderWater Pelletizers are suitable for pelletizing almost all types of polymers. Thanks to innovated pelletizing technology of UnderWater Pelletizers same size and same form of granules are cut continuously. Amount, diameter, and geometry of holes on die plate is chosen according to type of plastic and throughput.
Granules are transferred to dewatering centrifuge by water in stainless steel pipes. Dimensions of dewatering centrifuge is designed according to throughput. Steam fan is used for discharging the humid air inside the centrifugal dyer which is generated during dewatering.
UnderWater Pelletizers are completely made of AISI 304 stainless steel. Pelletizing blades and die plate are made of special alloy steels and coatings according to the type of plastic. By mobile parts, maintenance period is minimized.
