Tooling is cheap, blade changes take minutes, and pellet length is easy to tune. The weak point is wet material: strands break in the water bath if moisture is above ~1%, causing stop-starts that wreck throughput.<\/p>\n<h3 id=\"when-water-ring-pelletizing-wins\">When water-ring pelletizing wins<\/h3>\n<p>Water-ring sits between strand and underwater. The die face is in the open air but a high-velocity water ring quenches the pellet the instant it is cut. Operators get underwater-style pellet shape without the operating complexity of a pressurized water chamber. It is the default for PE\/PP masterbatch lines under 1,500 kg\/h.<\/p>\n<h3 id=\"when-underwater-pelletizing-wins\">When underwater pelletizing wins<\/h3>\n<p>Underwater is the only sensible choice for <strong>Pellettizzazione PET<\/strong> above 500 kg\/h and for any line that has to crystallize pellets inline (most PET bottle-to-bottle plants). The submerged cut gives a perfectly spherical pellet, which improves dryer airflow and downstream feeding consistency. The trade-off: tighter process control, higher capex, and dies that cost 3\u20135\u00d7 a strand die.<\/p>\n<h3 id=\"when-hot-die-face-air-cooled-wins\">When hot-die-face air-cooled wins<\/h3>\n<p>Air-cooled pelletizing is the rescue method for materials that hate water. Soft LDPE film with high MFI, EVA, hot-melt adhesives, and some TPEs all stick or clump in water. Air cooling gives a forgiving process at the cost of lower output and a slightly irregular pellet.<\/p>\n<hr \/>\n<h2 id=\"line-layout\">Layout della linea di pellettizzazione: spiegato ogni stadio<\/h2>\n<p>A pelletizing machine for plastic recycling is one node in a longer chain. A typical post-consumer film line looks like this:<\/p>\n<ol>\n<li><strong>Infeed and metering<\/strong> \u2014 belt conveyor with metal detector; weight-loss feeders for masterbatch or additives<\/li>\n<li><strong>Pre-compaction (for film\/fiber)<\/strong> \u2014 single-shaft compactor or agglomerator densifies low-bulk-density material to 300\u2013450 kg\/m\u00b3 so the extruder can feed it<\/li>\n<li><strong>Estrusione<\/strong> \u2014 single-screw for clean scrap, twin-screw for contaminated or multi-material feed; degassing zones remove moisture and volatiles<\/li>\n<li><strong>Filtrazione a fusione<\/strong> \u2014 screen changer (continuous or backflush) holds 80\u2013250 \u00b5m screens to catch paper, aluminum, gels<\/li>\n<li><strong>Die and pelletizing head<\/strong> \u2014 strand die, water-ring die, or underwater die plate; pellet size set by hole diameter and blade speed<\/li>\n<li><strong>Cooling and drying<\/strong> \u2014 water bath + centrifugal dryer (strand), or pellet\/water separator + dewatering screen (underwater)<\/li>\n<li><strong>Classification and storage<\/strong> \u2014 vibrating sieve removes fines and oversize; pellets go to silo or big-bag station<\/li>\n<\/ol>\n<p>The single most-skipped stage is <strong>filtrazione a fusione<\/strong>. Buyers spec pellet contamination in ppm; a backflush filter at 80 \u00b5m is the difference between a $900\/ton resale price and a $400\/ton one.<\/p>\n<hr \/>\n<h2 id=\"materials\">Guide specifiche per materiali: PET, HDPE, PP, pellicola PE<\/h2>\n<h3 id=\"pet-pelletizing\">Pellettizzazione PET<\/h3>\n<p>PET hydrolyzes when melted wet.

For washed PET bottle flake at 300\u20131,500 kg\/h, a dedicated <a href=\"https:\/\/www.energycle.com\/it\/pellettizzatori-di-plastica\/pellettizzatore-a-vite-singola-per-scaglie-di-bottiglie-in-pet\/\">PET bottle flake single-screw pelletizer<\/a> gives the best cost-per-ton \u2014 single-screw simplicity with PET-specific screw geometry and a vacuum vent sized for bottle-grade moisture.<\/p>\n<h3 id=\"hdpe-pelletizing\">Pellettizzazione di HDPE<\/h3>\n<p>UN <strong>Macchina per la pellettizzazione di HDPE<\/strong> is the most forgiving of the bunch. HDPE bottle flake, blow-molded scrap, and pipe regrind all run cleanly on a single-screw extruder with a water-ring or strand pelletizer. Typical line: shredder \u2192 wash \u2192 dryer \u2192 120\u2013160 mm single-screw extruder \u2192 backflush filter \u2192 water-ring pelletizer. Energy use lands at 280\u2013320 kWh\/ton; pellet resale tracks virgin HDPE at a 20\u201335% discount.<\/p>\n<h3 id=\"pp-pelletizing\">PP pelletizing<\/h3>\n<p>UN <strong>Macchina per pellettizzazione PP<\/strong> uses the same building blocks as HDPE, with two adjustments: a longer L\/D screw (33:1 or 36:1) to handle PP\u2019s narrower melt window, and a slightly cooler die. PP fiber and raffia waste \u2014 common at woven-bag plants \u2014 needs an agglomerator first because shredded fiber has a bulk density under 100 kg\/m\u00b3.<\/p>\n<h3 id=\"pe-film-pelletizing\">PE film pelletizing<\/h3>\n<p><strong>PE film pelletizing<\/strong> is where most beginner lines fail. Film cannot be fed directly to an extruder; the screw will just push air. The fix is a side-feed compactor that densifies film to ~400 kg\/m\u00b3 before it reaches the screw, plus heavy degassing because printed film carries inks and adhesives. Twin-screw extruders dominate this segment because they tolerate the 8\u201312% contamination that survives washing.<\/p>\n<hr \/>\n<h2 id=\"granulator-vs-pelletizer\">Scegliere un granulatore in plastica rispetto a un pellettizzatore<\/h2>\n<p>The terms get mixed up daily.

Compression pelletizing (used for biomass and some powders) presses material through a ring die without fully melting it. Compression equipment cannot process thermoplastic waste into resale-grade pellets.<\/p>\n<h3 id=\"can-one-pelletizing-machine-handle-pet-hdpe-and-pp\">Can one pelletizing machine handle PET, HDPE, and PP?<\/h3>\n<p>Mechanically yes, commercially no. The screw geometry, die temperature, and downstream drying for PET are different enough from HDPE\/PP that switching materials means a full shutdown, screw pull, and 4\u20138 hours of cleaning. Dedicated lines per polymer almost always pay back faster than a \u201cuniversal\u201d line that runs 50% of the time.<\/p>\n<h3 id=\"how-small-can-a-plastic-recycling-pelletizing-machine-get\">How small can a plastic recycling pelletizing machine get?<\/h3>\n<p>The smallest commercially viable line runs about 80\u2013100 kg\/h on a 65 mm single-screw extruder, priced around $35,000\u2013$55,000 in 2026. Anything below that is a hobby unit \u2014 fine for R&amp;D or 3D-printing filament prep, not for production resale.<\/p>\n<h3 id=\"what-pellet-contamination-level-do-buyers-accept\">What pellet contamination level do buyers accept?<\/h3>\n<p>For commodity HDPE and PP regrind, buyers typically accept 200\u2013500 ppm of foreign particles. Food-grade and fiber-grade specs drop to under 50 ppm, which requires a continuous backflush filter and often a second melt-filtration stage.<\/p>\n<h3 id=\"how-long-do-pelletizing-blades-last\">How long do pelletizing blades last?<\/h3>\n<p>On clean PE\/PP scrap, strand-cutter blades run 800\u20132,000 hours between regrinds. On glass-filled or mineral-loaded compound, blade life drops below 100 hours \u2014 budget for tungsten carbide or coated blades on abrasive feed.<\/p>\n<h3 id=\"is-air-cooled-pelletizing-cheaper-than-underwater\">Is air-cooled pelletizing cheaper than underwater?<\/h3>\n<p>Capex yes \u2014 an air-cooled head is 30\u201350% cheaper than underwater.
