I. Efficient Shredding of Large-Diameter Plastic Pipes
Large-diameter plastic pipes are widely used in water supply, drainage, gas transmission and industrial piping systems. During pipe production, installation and replacement, a large amount of waste pipes or production scraps are often generated, bringing challenges to storage, transportation and recycling. Given their bulky size and thick walls, conventional shredders usually require pre-cutting for these pipes.
To achieve efficient shredding of large-diameter plastic pipes, ACERETECH launches the PS Series Single-Shaft Plastic Shredder, specially designed for processing large-size HDPE, PVC and PP pipes. Equipped with a large-volume shredding chamber, hydraulic pusher system and intelligent control system, this machine can shred bulky plastic pipes into small fragments, preparing materials for subsequent recycling processes.
II. Challenges in Shredding Large-Diameter Plastic Pipes
Compared with ordinary plastic waste, large-diameter pipes present the following unique difficulties during processing:
1. Oversized dimension and thick pipe wall
Industrial-grade HDPE and PVC pipes often feature large outer diameters and thick walls. For instance, pipes with an outer diameter of 1200 mm and wall thickness of 110 mm require a shredding system with heavy-duty structure and strong processing capacity.
2. Difficult feeding
Long and oversized pipes are hard to be continuously fed into conventional shredders. Improper feeding will undermine processing stability and reduce overall production efficiency.
3. Stable shredding performance (consistent output size)
Pipes of different materials (e.g. HDPE and PVC) have distinct mechanical properties. The shredding system must be custom-configured according to material characteristics, pipe dimensions and required output particle size.
Therefore, selecting a suitable plastic pipe shredder is critical to building an efficient plastic pipe recycling line.
III. PS Series Single-Shaft Plastic Shredder for Pipe Recycling
The ACERETECH PS Series shredder is engineered for shredding large-diameter plastic pipes, bundled small-diameter pipes and plastic profiles. Thanks to its horizontal feeding layout and large-capacity shredding chamber, large-size pipes can be shredded directly without pre-cutting within the machine’s processing range.
This machine is suitable for recycling HDPE, PP and various PVC pipes, Key Features of PS Series:
1. Hydraulic Pusher Device
The hydraulic pusher feeds large-size pipes toward the rotor in a controlled manner to ensure stable feeding during shredding.
2. Laser Distance Control
The laser distance control system enables intelligent feeding management, coordinating feeding operations based on material position and machine operating status.
3. Heavy-Duty Rotor Design
It adopts a 1,430 mm diameter rotor fitted with 204 rotor knives and 5 stator knives. This heavy-duty structure is purpose-built for large-size, thick-walled plastic pipes.
4. Well-Known Brand Electrical Components & Motors
Motors and electrical parts from reputable brands guarantee reliable machine operation and consistent control performance.
5. Intelligent Control System
The intelligent control system coordinates machine operation and feeding functions, improving operational stability and simplifying equipment management.
IV. Actual Shredding Test: 1200 mm HDPE & PVC Pipes
To demonstrate the processing capacity of the PS Series, ACERETECH conducted machine tests using large-diameter HDPE and PVC pipes.
Test material specifications:
- Outer pipe diameter: 1,200 mm
- Wall thickness: 110 mm
- Pipe length: 6,000 mm
Test Results:
HDPE Pipe: 1,000 kg/h
PVC Pipe: 1,200 kg/h
The test results prove that the PS Series can handle oversized, thick-walled plastic pipes. Actual throughput may vary depending on material properties, pipe dimensions, feeding conditions and operating parameters.

VI. Application Fields Beyond Large-Diameter Pipe Shredding
Apart from large-diameter HDPE and PVC pipes, the PS Series can process various oversized plastic waste subject to different machine configurations.
Typical applications:
- HDPE water supply & drainage pipes
- PVC industrial and construction pipes
- PP plastic pipes and profiles
- Bundled small-diameter plastic pipes
- Large plastic blocks
- Stacked plastic bins and pallets
For recycling facilities and plastic pipe manufacturers, the PS Series serves as the primary volume reduction (shredding) machine in plastic pipe recycling lines.
Based on requirements of downstream processes, shredded fragments can be further processed by plastic pelletizers, washing equipment or other recycling machinery to prepare for subsequent reuse.
VII. Selecting the Right Plastic Pipe Shredding Solution
When choosing a plastic pipe shredder, maximum pipe diameter is not the only consideration. The following factors shall be comprehensively evaluated before confirming the machine configuration:
- Pipe material: HDPE, PVC, PP and other plastics
- Pipe dimensions: outer diameter, wall thickness and length
- Processing capacity: required hourly output
- Final particle size: size requirements of downstream processing equipment
- Downstream process: whether shredded materials will go to washing, pelletizing or granulation systems
Providing the above detailed information helps equipment manufacturers evaluate and determine the proper rotor setup, motor power, feeding system and auxiliary equipment.
