Precision Size Reduction
Use this industrial plastic granulator for final particle sizing after shredding, or for directly granulating bottles, runners, and smaller rigid scrap into uniform flakes for washing or pelletizing.
High-speed shear cutting for precise particle sizing.
Rigid plastics are fed via conveyor or cyclone into the cutting chamber. A hopper curtain prevents flyback.
The open rotor spins at 450-600 RPM. Angled knives shear material against fixed bed knives with a scissor-like action.
Material circulates until it is small enough to pass through the screen (typically 8-12 mm), ensuring defined flake size.
Sized flakes are pneumatically extracted or washed out (wet crusher) to preventing overheating and dust buildup.
Scissor-cut geometry and precise screen sizing deliver dust-free, consistent granules.
Open rotor design maximizes airflow and cooling, allowing sustained high-capacity operation.
Hydraulic hopper opening and screen cradle access make knife changing and cleaning rapid.
Excessive fines and dust reduce material value.
Optimized cutting angles and low rotor-to-knife gap minimize dust generation during crushing.
Machine overheating melts plastic, blocking screens.
Open rotor design and optional water-flush system keep the chamber cool during continuous runs.
Vibration and noise levels are too high.
Heavy-duty welded frame and optional soundproof enclosure reduce operational noise significantly.
Blade wear requires frequent downtime.
Knives are made from D2/SKD11 tool steel and can be resharpened multiple times.
Visual references for machine layout and downstream-ready material condition.
This view helps teams evaluate how core equipment is arranged between feeding, cleaning, and transfer stages in real plant layouts.
A consistent and manageable output condition improves control in washing, drying, and pelletizing workflows after this stage.

Yes, we offer wet granulator configurations with water inlets to pre-wash material and reduce friction heat/blade wear.
Depending on material cleanliness, knives typically run 40-80 hours before sharpening. They can be sharpened multiple times.
Yes, due to high-speed operation, we recommend our integrated soundproofing cabin to keep noise levels below 85 dB.
This granulator uses high speed impacts to cut small flakes. A shredder uses low speed torque to tear big chunks.
