SP Three models are included in Coperion’s line of dual-bearing strand pelletizers — the SP140, SP240 and SP340 — with throughputs of about 220 pounds per hour to about 6,614 pounds per hour. They feature a pellet outlet chute with soundproof cladding, a frequency-controlled rotor drive and upper feed roll, as well as pneumatic control of feed roll pressure.
What’s new? Improvements to speed recipe and color changes. The pelletizers have been the subject of myriad upgrades over the past few years. Most recently, Coperion has made the cutting chamber design more compact, and optimized the product strand-intake area so that strands are now continuously and directly guided into the cutting section. Also optimized are the flanges on the cutting rotor, designed to use the entire width of the rotor.
Benefits Reduced downtimes and even better pellet quality, along with faster setup, and easier cleaning and maintenance. The pelletizers’ cut quality is constant and very high, even when pelletizing soft polymers. Thanks to the new design, there’s no dead space in the cutting chamber, reducing cleaning time. The cutting unit can be swapped out quickly and easily, without the use of tools. Also, the pelletizers’ interior has improved accessibility and is very easy to clean.
