Product Category: Pelletizer

Strand pelletizer with speed regulation and programmable inverter. Knife speed from 0 to 1200 RPM, strand-feeding speed from 0 to 72 meter per minute.  Modern designed full steel body with stainless steel bottom platform as well as a smaller adjustable stainless steel platform for holding smaller discharge bags or containers. The smaller platform can be lowered all the way down to the large platform giving room for larger discharge drums without removing the small platform.

The pelletizer uses a fan-shaped cutting wheel that cuts the strands sideways with a scissors action.  The machine can be used to pelletize practically any type of thermoplastic resin, even materials that cannot be pelletized using conventional machines, i.e. ‘rubbery’ materials such as soft PVC and thermoplastic elastomers.  Because of the gentle shear cut action obtained with this Sidecut pelletizer, even highly filled and brittle strands can be pelletized without causing dust and shattering of the pellets.

The underwater pelletizer units are built up on completely self-supporting frames. The parts of the line that come into contact with water are made from stainless steel. All internal and external panels of the pelletizer sub-cabinet, and the panels of the control cabinet, have undergone a rigorous painting regime using triple priming with each layer being carefully sanded before applying the next layer. The final painting (top coat) consists of two layers of highly resistant epoxy paint.  The pelletizer is equipped with six steel cutting blades mounted on a flexible plate attached to a sturdy spring-loaded shaft.  The rotating arm (with cutting blades) unit can be adjusted forwards and backwards so that a suitable cutting blade force can be applied to the die face for cutting the extruding molten strands.  When cold circulating water is being used for the pelletizer the heat exchanger is cooled ‘externally’ using cold water supplied from a chiller (or from the mains or from a cooling tower, if one is available). The water that passes to the pelletizing unit travels around the cooled copper pipes inside the heat exchanger unit. In this way the cooled circulating cooling water for the pelletizer does not become contaminated since it does not come into direct contact with the water used for cooling the heat exchanger.
