What a Plastic Granulator Does and Where It Sits in Your Line
A plastic granulator is the precision size-reducer that turns scrap into uniform regrind for extrusion, pelletizing, washing, or resale.
A plastic granulator reduces runners, sprues, defective parts, bottles, film, pipe, and sheet into uniform regrind granules, typically 4-18 mm. Where a shredder tears large items into coarse strips at high torque and low rpm, and a pelletizer turns molten polymer into round pellets, the granulator sits between them with high-speed rotors, tool-steel blades, and a sizing screen that defines final particle size. For injection-molding shops, a beside-the-press granulator reclaims hot runners in-line. For recycling plants, a central granulator downstream of a shredder produces the regrind that feeds a washing line, extruder, or pelletizer. For machine comparisons, see our Schredder vs. Granulatierer vs. Pelletizer guide or read Funktionsweise eines Kunststoffgranulators. Planning a turnkey project?

Wie wählen Sie die richtige Kunststoff Granulatiermaschine in 4 Fragen
Use these four checks to narrow the machine type before sizing the rotor, motor, screen, and blade steel.
1. What is your feedstock?
Bottles and film: wet or PET-flake granulator. Rigid lumps and purging: heavy-duty rigid. Long pipe and profile: vertical. Mixed or unsorted bulky scrap: integrated shredder-granulator.
2. Wie hoch ist Ihr Durchsatz?
Beside-the-press reclaim: 50-200 kg/h. Mid-scale recycling: 300-900 kg/h. Central plant: 1,500-2,000 kg/h. Size 20% above peak to protect the motor.
3. Welche Granulatgröße benötigen Sie?
Extruder feed: 6-10 mm. Pellet line: 8-14 mm. Resale as flake: 10-18 mm. See our Siebgrößenanleitung.
4. Schmutziger oder sauberer Eingang?
Clean scrap: standard D2 or SKD-11 blades. Labeled bottles or film with sand: wet granulator plus stainless hopper. Glass-filled or fiber-reinforced scrap: CPM-10V or carbide.

Ersatzmesser für Granulatoren
Rotor and bed knives in SKD-11, DC53, and CPM-10V. HRC 58-62. Custom lengths for any rotor diameter.
SchärfungAutomatischer Messerschleifer
Resharpen granulator blades to ≤0.03 mm precision. 6-10 re-grinds per blade set before replacement.
AnleitungGranulatormesser auswählen
Match blade steel, bevel angle, and hardness to your plastic feedstock.
Cost AnalysisBlade Material vs. Cost
When premium steel pays back, and when D2 is the right answer.
Keep Every Granulator Running at Peak Output
A simple maintenance rhythm protects output, energy cost, and regrind consistency.
Knife clearance – weekly
Rotor-to-bed knife gap should stay within 0.15-0.30 mm. A gap above 0.5 mm wastes 15-25% of motor energy and tears plastic instead of cutting.
Siebprüfung
Replace bent or worn screens. Holes elongated beyond 110% let oversize regrind through. See how screen size affects quality.
Resharpen, do not replace
Tool-steel blades can be reground 6-10 times. An automatic grinder pays for itself within one blade set.
Bearing & belt schedule
Grease bearings every 500 hours and retension V-belts every 200 hours. See our Wartung Und Fehlerbehebung guides.
