Pipe Chipping Machines
Unlike a conventional low-speed pipe shredder, this machine works more like a wood chipper — high-speed rotary blades continuously chip long plastic pipes into manageable flakes. Simple direct feed, no hydraulic pusher required, compact footprint. Ideal first-stage volume reduction for regular PE and HDPE pipes before washing or granulation.
Think wood chipper, not shredder. The machine is optimized for continuous feed of regular-shaped plastic pipe — fast, simple, and compact.
Long PE or HDPE pipes slide directly into the feed opening. No hydraulic pusher mechanism is required — the pipe is drawn in continuously as the rotor cuts. This eliminates pre-cutting labor and simplifies the feed process.
Hardened rotary blades chip the pipe at high speed, similar to a wood chipper working through timber. The cutting action reduces the pipe into flat chips or flakes quickly, making it suitable for fast volume reduction.
Output chip size is governed by rotor speed and blade count — no screen is required for primary reduction. This keeps the design simple and reduces maintenance compared to screen-based shredders.
Chips are conveyed by blower or belt to a secondary crusher, friction washer, or granulator for final size reduction. The chipping stage handles bulk volume reduction; downstream equipment achieves the final pellet-ready particle size.
Continuous direct feed means long PE and HDPE pipes — even 6 m lengths — are processed without pre-cutting or repositioning. Throughput per hour is high for compatible, regular-shaped material.
No hydraulic pusher, no long infeed trough, no complex force-feed mechanism. The chipper design is mechanically simpler than a horizontal shredder, reducing footprint and maintenance points.
Optimized for consistent round-section PE/HDPE pipe, the high-speed rotor delivers fast volume reduction per kilowatt compared to low-speed tearing on compatible material grades.
Quickly reduces bulk pipe volume before a crusher, friction washer, or pelletizing system — cutting handling and transport costs at the front of the recycling line.
The machine is optimized for regular, round-section PE/HDPE pipe — not all plastic waste.
Irregular plastics, bulky drums, blocks, profiles, or mixed material shapes do not feed reliably. If your feedstock varies widely in shape, a low-speed single-shaft shredder with hydraulic pusher is a better fit.
High-speed blades are more sensitive to metal contamination than low-speed shredder knives.
A magnetic separator and metal detector upstream is strongly recommended. Hard foreign objects — metal inserts, concrete, fittings — cause rapid blade damage at high cutting speeds.
Output is chips or flakes, not screen-controlled regrind.
The chipper produces primary chips that typically require a downstream crusher or granulator to reach pelletizer feed size. If you need screen-controlled, uniform regrind in one step, a shredder with bottom screen is more suitable.
Higher noise and vibration than low-speed shredding.
High-speed rotary chipping is louder and creates more vibration than low-speed high-torque shredding. Acoustic enclosures or hearing protection zones should be factored into the plant layout.

Use this reference to evaluate pipe OD, wall thickness, and bundle configuration before confirming the shredder model and hopper width.
Coarse regrind from the shredder is ready for a crusher, washing line, or bulk storage. Screen size determines the output window.

Regular-section municipal, agricultural, and gas PE pipes for collection and recycling campaigns where fast volume reduction is the priority.
Clean or lightly contaminated PE and HDPE offcuts from extrusion lines, where consistent pipe shape makes chipper feeding reliable and fast.
First-stage volume reduction before a friction washer, wet granulator, or pelletizing system — handling bulk pipe lengths that cannot be directly fed into downstream size reduction equipment.
Suitable for regular-section PP and rigid PVC pipe where pipe shape is consistent and contamination is low. Confirm blade and rotor specification for PVC with Rumtoo before ordering.
Where floor space is limited and feedstock is regular pipe, the chipper is a compact alternative to a full horizontal shredder line.
Where throughput per square meter of floor space is a priority and feedstock is clean, consistent PE pipe, the high-speed chipper outperforms low-speed shredders on volume-per-hour.
| Model | Typical Throughput | Sizing Reference |
|---|---|---|
| PCM-500 | 200–400 kg/h | Rotary Chipper | 30 kW | Feed opening 900 × 600 mm | Rotor 500 mm | Screenless |
| PCM-1000 | 400–600 kg/h | Rotary Chipper | 55 kW | Feed opening 1200 × 800 mm | Rotor 700 mm | Screenless |
| PCM-1500 | 600–800 kg/h | Rotary Chipper | 90 kW | Feed opening 1500 × 1000 mm | Rotor 900 mm | Screenless |
| PCM-3000 | 800–1200 kg/h | Rotary Chipper | 160 kW | Feed opening 2000 × 1200 mm | Rotor 1100 mm | Screenless |
Use these models for planning. Final sizing is confirmed by pipe OD, wall thickness, material grade, and contamination level.
A pipe chipper performs best with regular, round-section PE/HDPE pipe and clean or lightly contaminated feedstock. Confirm the following before specifying.
Provide the OD range, typical wall thickness, and maximum pipe length. If the feedstock is predominantly round-section, consistent pipe, a chipper is suitable. If you handle drums, blocks, profiles, or heavily mixed shapes, specify a low-speed shredder instead.
Specify contamination type — soil, fittings, or metal inserts. Light soil contamination is manageable; metal inserts require upstream detection and removal. Heavy or variable contamination favors a low-speed shredder with higher blade tolerance.
Confirm whether chips feed a crusher, washing line, or granulator. The chipper handles primary volume reduction. If a specific particle size is needed in one step, a shredder with a bottom screen may be a better match.
State the required kg/h and how pipes arrive — manual roll-in, conveyor, or crane. The chipper handles continuous long-pipe feed well; for bulk-dumped irregular material, a top-feed shredder is more forgiving.
| Criteria | Pipe Chipping Machine | Horizontal Pipe Shredder |
|---|---|---|
| Cutting principle | High-speed rotary chipping — like a wood chipper | Low-speed high-torque tearing with hydraulic pusher ram |
| Best feedstock | Regular round-section PE/HDPE pipe, consistent shape | Oversized or irregular pipe up to Ø2,000 mm, whole 6 m lengths |
| Feed mechanism | Direct continuous pipe feed — simple, compact | Long hydraulic pusher (up to 7,500 mm stroke) |
| Output | Chips/flakes — primary reduction, downstream crusher needed | Screen-controlled regrind — selectable output size |
| Footprint | Compact — no long infeed trough or pusher frame | Large — long hopper and hydraulic frame required |
| Noise & vibration | Higher — high-speed chipping is louder | Lower — low-speed high-torque is quieter |
A pipe chipping machine uses high-speed rotary blades to chip pipe quickly — similar to how a wood chipper works. A pipe shredder uses a low-speed, high-torque rotor to tear through material more slowly. The chipper is faster and more compact for regular-section pipe; the shredder handles larger OD, irregular shapes, and heavier contamination more reliably.
The machine is optimized for regular round-section PE and HDPE pipes. Standard models handle diameters up to 400–800 mm OD depending on model. PP and rigid PVC are also processable — confirm blade and rotor specification with Rumtoo for PVC. Irregular, bulky, or non-pipe plastic waste is not suitable.
No. Long pipes feed continuously and directly — the machine draws the pipe in as the rotor cuts. Pre-cutting is not required and eliminates a labor step upstream.
Output is chips or flakes determined by rotor speed and blade geometry, typically 30–80 mm for primary chipping. This is not screen-controlled regrind — a downstream crusher or granulator is required to reach pelletizer feed particle size.
Yes — more so than with a low-speed shredder. High-speed blades are sensitive to hard foreign objects. A magnetic separator and metal detector upstream is strongly recommended. Pipes with embedded metal fittings or concrete should be cleaned before feeding.
For compatible regular-section PE/HDPE pipe, the chipper can deliver higher throughput per kilowatt than a low-speed shredder. For irregular, oversized, or heavily contaminated material, a low-speed shredder is more suitable and may achieve better effective throughput.
Send pipe OD range, wall thickness, material grade (PE/HDPE/PP/PVC), contamination type, required kg/h, downstream process (crusher/washer/granulator), and feeding method. Photos or video of the actual feedstock are very helpful.
It depends on your feedstock. If your material is regular-section PE/HDPE pipe with low contamination, a chipper is a compact and fast alternative. If you process oversized pipe (above 800 mm OD), irregular shapes, or heavily contaminated post-consumer material, a horizontal pipe shredder with hydraulic pusher is more appropriate.
Send your pipe dimensions, material grade, contamination profile, and throughput target. Rumtoo will recommend the right machine and explain the difference in plain terms.
