  • Powerful, Controlled Shredding

    Low‑speed (60–100 rpm) rotor with hydraulic pusher delivers high torque and stable feed.

  • Wear‑Resistant Tooling

    Square, indexable SKD11 (D2) knives with hardened counter knives for long life.

  • Consistent Output Size

    Replaceable screens (typically 20–80 mm) define particle size for downstream processing.

  • Easy Service & Safety

    Hydraulic hopper/ram, swing‑out screen cradle, guarded access and interlocks reduce downtime.

Video Walkthrough

See the Single‑Shaft Shredder in Action

Watch controlled, low‑speed shredding of bulky plastics. See how the hydraulic pusher meters material into the rotor and how the screened discharge guarantees consistent particle size for downstream processing.

  • Hydraulic pusher keeps material moving for steady load and high torque.
  • Square, indexable knives deliver clean cuts and long tool life.
  • Screened discharge ensures uniform particles and smoother downstream throughput.

Slow‑Speed, High‑Torque Shredding for Demanding Materials

Built for thick, hard‑to‑cut materials—plastic blocks and sheets, injection runners, buckets and drums, pallet strips, purgings, and PE/PP/PVC pipes—our single‑shaft shredder delivers consistent chip size and high uptime. Compared with high‑speed granulators, it runs quieter and handles bulkier, contaminated feedstock with less risk of jams. The machine can be paired with conveyors and downstream granulators to form a two‑stage reduction line that maximizes throughput and blade life.

Output

Screened chips/flakes (typically 20–80 mm) for stable feeding to crushers, washers, and conveyors.

Best For

Bulky rigid plastics: lumps, pipes, drums, purgings, thick runners, and mixed rigids.

Hydraulic Pusher

Smart load control meters tough materials into the rotor and prevents bridging.

Closed Rotor with Square Knives

Staggered knife layout maximizes bite; knives are bolted for quick indexing and replacement.

Screened Discharge

Material stays in the chamber until it reaches the target size, improving downstream efficiency.

System Integration

Works with belt conveyors, metal detectors, and granulators for two‑stage reduction.

Where It Fits in a Recycling Line

  • Upstream: Manual feeding or conveyor (optional metal detection)
  • This stage: Primary size reduction for bulky rigid plastics into screened chips
  • Downstream: Crusher for finer flakes; then Washing or PET lines
