INDUSTRIAL PIPE RECYCLING

Machine for grinding HDPE pipes with large diameter

This heavy-duty HDPE/PE pipe shredder is designed for direct processing of complete pipes without pre-cutting. Thanks to horizontal feeding and a PLC-controlled hydraulic pusher, thick pipes are safely and controlled reduced to uniform chips for industrial recycling lines. Standard models process pipes up to Ø1200 mm; custom configurations are possible up to Ø3500 mm (model-dependent) and for lengths up to 6000 mm+.

  • Direct feeding of whole HDPE/PE pipes – no pre-processing required
  • Standard models up to Ø1200 mm, custom up to Ø3500 mm
  • PLC-controlled hydraulic pusher prevents bridging
  • Output size 40–120 mm, matched to washing and extrusion lines
  • Capacity up to 800–1200 kg/h (material-dependent)

Machine for grinding large diameter HDPE pipes

Conventional shredders often have difficulty gripping thick, large pipes. This system combines a wide horizontal feed trough, high torque, and intelligent load regulation, so that the machine continuously produces with lower risks for operators and lower downtime costs.

Horizontal input for large HDPE pipes

Horizontal feeding without pre-processing

The wide feed system makes it possible to load long and heavy pipe sections directly with forklift or crane. This eliminates manual pre-cutting, which increases safety and significantly shortens the processing time per batch.

Hydraulic pusher with PLC control

The hydraulic ram feeds the material continuously under controlled pressure towards the rotor. The PLC automatically adjusts the feeding speed based on motor load, thereby drastically reducing blockages, peak currents, and downtime.

Rotor and blades for thick HDPE pipes

High torque and wear-resistant cutting set

The low-speed rotor with high torque efficiently cuts thick pipe walls into homogeneous chips. Adjustable counter knives and replaceable screens ensure a constant output quality for downstream processes such as washing and extrusion.

Applications and material fit

Municipal HDPE water pipes

Reliable processing of large diameter infrastructure pipes.

Gas and infrastructure pipes

Suitable for thick walls and long sections.

Rejection from extrusion production

Direct reduction of production waste without pre-processing.

Long HDPE pipe sections

Stable input of complete lengths up to 6000 mm+.

Post-consumer HDPE pipe waste

Uniform chips for further recycling processes.

Why choose this large diameter pipe shredder?

  • ✓Processing of whole pipes without pre-cutting
  • ✓PLC-controlled hydraulic material feeding

Process flow

From whole pipe input to uniform output for further processing

1. Loading

Complete pipes or long sections are horizontally fed with a forklift or crane.

2. Controlled feeding

The hydraulic ram feeds the material automatically and adjusts the force to the work load.

3. Reduction

The rotor and counter knives cut thick pipe walls into homogeneous chips with a stable energy profile.

4. Throughput

Material passes through the screen and goes directly to washing, further reduction, or extrusion.

Performance Comparison

Why this design performs better with large diameter pipes

Conventional shredder

  • Often requires preliminary sawing work
  • Manual or gravity feeding
  • Susceptible to clogging
  • Irregular output fraction

This machine

  • Direct input of whole pipes
  • PLC-controlled hydraulic ram
  • Load regulation with fewer blockages
  • Consistent chips for line integration

Capacity and particle size are dependent on material, pipe wall thickness, and selected configuration.

Frequently Asked Questions

What is the maximum pipe diameter that this machine can handle?
Standard models process pipes up to Ø1200 mm. For larger diameters, we offer customized solutions up to Ø3500 mm, depending on material and configuration.
Can I set the output size?
Yes. The output is determined by the selected sieve. Typical fractions range between 40 and 120 mm, tuned to your washing or extrusion line.
Is the machine also suitable for PVC pipes?
PVC can be processed, but for structural high PVC capacity, we recommend a specific PVC granulator or a customized line setup.
How is clogging in the hopper prevented?
The PLC-controlled hydraulic ram maintains constant pressure on the material and dynamically regulates the feeding speed based on rotor load.
Can this system be supplied as a complete recycling line?
Yes. We provide complete solutions including conveyer belts, crushing, washing, drying, and pelletizing.
