Used Plastic Pelletizers & Pelletizing Lines for Sale

A plastic pelletizer is the downstream cutting system at the end of a plastics compounding or recycling extrusion line. Its job is to convert the molten polymer leaving the extruder die into uniform, free-flowing pellets that can be packaged and shipped, or fed back into a downstream molding or extrusion process. The pellet shape, size, and consistency directly affect how the resin handles in conveying systems, drying, and dosing — so pelletizer choice has a meaningful impact on resin quality.

Plastic pelletizers fall into four broad categories. Strand pelletizers extrude polymer strands through a die, cool them in a water bath, dry them on a blower or air knife, and chop them with a rotary cutter into cylindrical pellets — the simplest and most common approach for compounders up to about 5,000 lb/hr. Underwater pelletizers cut the polymer directly at the die face under water, producing nearly spherical pellets — ideal for high throughputs, sticky resins, low-viscosity polymers, and post-consumer recycling. Water-ring pelletizers cut at the die face with a rotating water ring — common for polyolefins and PVC. Air-cooled die-face cutters are used for low-temperature applications and certain hot-melts.

When buyers search for “plastic pelletizer,” “pelletizing line,” or “plastic pelletizing extrusion,” they usually evaluate throughput (lb/hr), polymer type, pellet shape, system footprint, and brand. Gala (now part of Maag), Coperion, Davis-Standard, BKG (Nordson), Reduction Engineering, and Beringer are leading brands. Meadoworks regularly handles used pelletizers and complete pelletizing lines from compounders consolidating equipment or upgrading capacity.
