Single‑Shaft Plastic Shredder
Heavy‑duty, hydraulic‑pusher single‑shaft shredder engineered by Rumtoo Machine for tough size‑reduction tasks. Ideal for plastic blocks and sheets, buckets and drums, extruded pipes, as well as wood, paper, textiles, packaging, biomass, and more.
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.

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.
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.
