Strand pelletizers are used to cut pellet for most thermoplastic materials to make a uniform pellet.
Strand pelletizers have many advantages compared to underwater/watering pelletizers including low cost, simplicity, and quick to clean and change materials. Stand pelletizers can have a solid milled helical rotor for a quieter operation, or bolt on rotor with replaceable blade rotor for more durability. A stand pelletizing line can be used with a water bath or waterslide for cooling. Typically an air knife is used to dry the strands before they are cut by the pelletizer, however there a few wet cut models available. Pelletizers are controlled with AC or DC Drives and use pull rolls to guide the strands into the cutter.
