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>Peletizace 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\">Rozvr\u017een\u00ed linky pelletizace: vysv\u011btlen\u00ed ka\u017ed\u00e9ho kroku<\/h2>\n<p>A pelletizing machine for plastic recycling is one node in a longer chain.

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\">Volba mezi granul\u00e1torem a pelletiz\u00e9rem<\/h2>\n<p>The terms get mixed up daily.
