Our heavy-duty industrial granulators are engineered for 24/7 size-reduction of the thickest, toughest plastics, metals, rubber and wood waste. From central-plant bulk recycling to in-line production scrap, one machine turns bulky parts into uniform, high-quality regrind in a single pass.
✓ One-step granulation eliminates pre-cutting labor
✓ Uniform regrind raises extrusion recycle rate 15–25 %
✓ Extended blade life and hydraulic access cut maintenance cost up to 40 %
✓ Modular build allows hopper, conveyor, blower and metal-separator to be added later
Product Features
Mega-Diameter Rotor – Ø600–1 100 mm forged steel with 9–13 knife rows delivers up to 30 % higher torque and swallow-proof intake for bulky walls, pipes and purgings.
Segmented Knife Frame – patented "claw" layout distributes cutting forces evenly, lowers noise and guarantees self-feeding of hollow shapes.
Wear-Resistant Build – housing, rotor and screen plasma-hard-faced; optional 600 Brinell tool-steel knives last 4× longer than D2 and can be re-sharpened multiple cycles.
Intelligent Screen System – quick-change 8–60 mm screens with laser-cut tolerance give consistent flake size for downstream extrusion or injection.
Dust-Tight & Low-Noise – integrated dust-extraction port and double-wall sound insulation keep workplace below 80 dB(A).
Safe & Fast Maintenance – hydraulically pivoting hopper and screen cradle provide full access in <3 min, reducing downtime by 70 %.
Automation Ready – Ethernet/IP interface for automatic feed, metal-detector, and load-based speed control; compatible with shredder-secondary stage for >3 t h⁻¹ throughput.
Product Applications
- Thick-walled pipes, automotive bumpers, COEX fuel containers up to 150 °C
- Glass-fiber reinforced, highly filled or abrasive engineering plastics
- After shredding, the material is passed through a heavy-duty industrial granulator for plastics recycling to produce a high-bulk-density regrind with a particle size below 6 mm.
- Edge trim, sheet, film and thermoforming skeletons (with tangential chamber option)
Service & Support
- OEM & ODM customization for rotor geometry, drive power (45–400 kW) and wear package
- Global on-site start-up, operator training and process optimization
- 24 h spare-parts logistics and remote diagnostics
- ISO-9001 & CE certified manufacturing; warranty up to 24 months or 6 000 operating hours
