Strand pelletizers are used for cutting thermoplastic plastic strands.
Strand pelletizers
The COLLIN strand pelletizer basic system has one drive – for a pre-defined pellet length of approx. 3 mm.
The strand pelletizer with two independent, variable drives enables the stepless adjustment of the pellet length from 0.8 up to 5 mm.
Moreover, COLLIN offers pelletizers, which are designed for more than two strands and for a higher take-off speed.
Advantages
Compact system
Variable in design resp. drive
Depending on the customer requirements, underwater as well as die face pelletizers can be delivered:
Underwater Pelletizing Systems (UWP)
With this system, the polymer is directly cut at the die plate under water. Together with the water, the pellets are guided into the drying system, in which the water is separated from the pellets. The water system is tempered in order to enable a constant process. The pelletizer includes die plate, cutting device and the tempered water system. As option, COLLIN offers a polymer diverter valve.
The compact unit is mounted on a moveable frame and, by a clamping flange, it can easily be connected with the extruder.
The die plates are available in different die designs and heatings.
Advantages
Wide viscosity range can be pelletized
Less dust
Micro-pellets are possible
Low noise level
Die face pelletizer air-cooled (AP)
With this system, the polymer is directly cut at the outlet of the die plate. In contrast to the underwater pelletizing system, COLLIN uses a blower for creating an air flow in order to transport the pellets into a cyclone. The system includes a die plate, cutting device and a cyclone. The complete unit is mounted on a moveable frame and by a clamping flange, it can easily be connected with the extruder.
Advantages
Compact system
Low operating pressure
Easy and quick cleaning
Visibility of the cutting process – transparent window
autarkic – stand-alone machine
