Product Description
The Large Diameter HDPE PP PE Pipe Crusher is a horizontal pipe granulator that accepts whole large diameter pipe up to 800 mm outside diameter, with cutterless infeed for HDPE, PP and PE. The published family reference machine runs at 185 kW with a two stage feed opening (500 x 500 mm upper, 650 x 650 mm lower), a 10 blade rotor and a 30 mm box plate chamber, and it feeds pipe through an integrated 650 mm x 4 m infeed conveyor.
The number that matters on a large diameter pipe crusher is the feed opening, because that sets how large a pipe can enter without pre-cutting. The published reference machine uses a 650 x 650 mm lower opening, which supports HDPE pipe up to 630 mm outside diameter; the extended configuration is confirmed up to 800 mm outside diameter for HDPE, PP and PE pipe. The full specification of the 800 mm platform is confirmed at enquiry, because a larger platform is a confirmed configuration rather than a guessed figure.
Two stage feeding is what makes this machine practical across a pipe plant. The lower opening accepts whole large diameter pipe; the upper opening takes shorter offcuts, smaller pipe, purgings and profile scrap in the same machine. One unit covers both the heavy end and the small end of a pipe plant's waste stream.

The family reference machine is published at 630 mm with 185 kW and a 650 x 650 mm lower feed opening; the extended configuration accepts HDPE, PP and PE pipe up to 800 mm outside diameter, with the full specification confirmed at enquiry.
For the 800 mm layer we confirm these items on the order specification rather than printing estimates:
Feed opening dimensions for the 800 mm configuration
Main drive power for the 800 mm configuration
Rotor, blade count and blade geometry for the 800 mm configuration
Box plate thickness and overall dimensions
Conveyor size for your pipe lengths and site layout
Match the opening to the pipe. The lower opening is the number to compare with your largest pipe outside diameter. On the published reference it is 650 x 650 mm and supports 630 mm pipe; the 800 mm configuration is confirmed against your pipe at enquiry.
Think about wall thickness, not only diameter. Thick wall HDPE pipe needs the drive and the blade geometry to be sized for continuous load, which is why the 185 kW reference figure is worth noting even when you order a different configuration.
Plan the conveyor against your pipe length. The standard reference conveyor is 650 mm x 4 m; longer pipe means a longer conveyor, and that is a confirmed item rather than a fixed one.
Include the small end. Offcuts, purgings and profile scrap go through the upper 500 x 500 mm opening, so one machine covers the whole plant waste stream.
Confirm power supply early. The reference drive is 185 kW three phase; your voltage and frequency are built into the electrical control cabinet.
Related lines in the same family: 3 layer high speed PE PPR HDPE pipe extrusion line, ppr pipe extrusion line solution, pvc pipe extrusion line solution and corrugated pipe extrusion line solution.
Materials and products. The extended configuration processes HDPE, PP and PE pipe up to 800 mm outside diameter. The published reference machine is set up for HDPE pipe, and the same machine family covers the two stage feed arrangement for the whole pipe waste stream, from full length large pipe down to offcuts and purge blocks.
Applications. The machine is aimed at any operation that produces or collects large diameter pipe.
| Application | Typical material | Why this machine fits |
|---|---|---|
| HDPE pipe extrusion plants | Pipe start-up scrap, out-of-spec pipe, purge blocks | Whole pipe feeds in directly from the line side, no pre-cutting |
| Pipe installation and utility contractors | Offcut and rejected lengths of large diameter pipe | Compact main machine, conveyor-fed loading |
| Water supply and gas pipeline projects | Heavy wall HDPE service pipe | 185 kW reference drive handles thick wall without stalling |
| Municipal drainage and sewer projects | Large diameter drainage pipe | Lower 650 x 650 mm opening takes full pipe sections |
| Pipe stockyards and traders | Mixed stock, damaged pipe, end-of-life pipe | Upper 500 x 500 mm opening handles smaller pipe and offcuts too |
| Plastics recycling plants | HDPE pipe collected from multiple sites | Conveyor infeed for continuous, single-operator feeding |
Working conditions. The machine is installed at floor level as a complete set, main machine plus infeed conveyor and control cabinet. It needs a level, load-bearing concrete floor, a suitable three-phase power supply for the 185 kW reference main drive, and enough clear space in front of the conveyor to lay down a full pipe length before feeding. The horizontal layout keeps height clearance low, which helps when the crusher is added to an existing pipe shop.
Who this machine suits
Pipe extrusion plants running HDPE, PP or PE lines that want one crusher for both full length reject pipe and line-side scrap.
Contractors and utilities that handle large diameter pipe on site and want to avoid trucking whole pipe away.
Municipal and drainage projects that generate heavy wall pipe waste.
Stockyards and traders that hold mixed and end-of-life pipe.
Recycling plants that collect large pipe from multiple sites.
The drainage pipe side of the plant is covered under plastic drainage pipe machine. Where the plant also makes pressure pipe, the same extrusion technology appears on single wall corrugated pipe extrusion line and double wall corrugated pipe extrusion line.
This is a built to order machine. Customization is about matching the platform to your pipe, your wall thickness and your plant layout.
What we will change
Conveyor length and width. The standard reference conveyor is 650 mm x 4 m; longer or shorter conveyors are discussed together with your pipe lengths.
Voltage and frequency. The electrical control cabinet is built for your plant supply.
Feeding arrangement. The position of the conveyor relative to the chamber can be adapted to your floor layout.
Blade configuration. Blade material and edge geometry are selected for the pipe wall thickness you process.
Discharge arrangement. Discharge height and direction are adapted to your downstream conveying.
Complete recycling line integration. The crusher can be supplied as part of a plant that includes washing, drying and pelletizing.
What is fixed by the platform
The published reference machine carries 630 mm as its top published pipe size. Larger pipe moves to the extended 800 mm configuration, and the 800 mm figures are confirmed at enquiry rather than printed as estimates.
The reference feed opening dimensions, 500 x 500 mm upper and 650 x 650 mm lower, as published for the 630 mm unit.
The reference 10 blade rotor and 30 mm box plate construction, the published structural specification of the 630 mm unit.
The reference main drive power of 185 kW, sized to the published cutting chamber.
The reference overall dimensions of 3900 x 1800 x 2500 mm, fixed by the published frame.
No figure is invented for the 800 mm layer. Numbers that are not published for the reference unit are confirmed at enquiry and written into the quotation.
Equipment that pairs with the crusher includes washing line machines, washing and recycling production line, plastic pelletizing line, two stage recycling machine, crushing material suction machine and continuous powder suction machine.
Quality control on a machine of this size is about structure and repeatability, not only appearance.
Frame and chamber. The horizontal chamber is built from 30 mm box plates, a heavy fabricated structure rather than a folded sheet housing, so the cutting chamber holds its geometry under continuous large pipe loads.
Rotor assembly. The reference rotor carries 10 blades and runs as a complete assembly on the test run before dispatch, so the machine is checked for smooth running at the installed drive power.
Hydraulic system. The box opening cylinder and its 3 kW hydraulic cylinder motor are function-tested through full open-and-close cycles before dispatch.
Conveyor and control. The 650 mm x 4 m conveyor and the electrical control cabinet are wired and run as a set, so commissioning on site is a matter of connection and check rather than assembly.
Pre-delivery inspection. Incoming steel plate and components are inspected, the fabrication process is patrolled, and the complete machine is re-inspected before delivery.
Warranty and documentation. The machine is supplied with a 1-year warranty and with the machine manual, wiring diagram and hydraulic diagram.
Manufacturing follows ISO 9001 quality management, and machines are supplied with CE marking for export markets. Chenxing Machinery was established in 2002, has worked in plastic machinery for over 20 years and has been exporting for 16 years, based in China.
Chenxing also builds the equipment that surrounds a crusher, so the whole line can be specified by one supplier: see auxiliary machines, automatic compounding system, mixing unit, powder suction machine and the advanced material processing EPC project service.
MOQ. One set. Each crusher is built to order against the confirmed specification, so a single set is the normal starting quantity; multi-set orders for a group of plants are quoted together.
Scope of supply per set. Main machine, infeed conveyor (650 mm x 4 m, 4 kW) and electrical control cabinet (1 unit), plus blades as specified.
Payment terms. T/T, L/C and Western Union.
Incoterms. FOB, EXW, CFR, CIF and CIP.
Lead time. Confirmed at order, since the machine is built to specification; ordering earlier in the year avoids peak season pressure.
Packing. Export packing suitable for sea transport, with the main machine secured on a reinforced base, and the conveyor and cabinet packed separately.
Shipping. The whole set is shipped as one consignment; the loading plan and container or flat-rack arrangement are confirmed before dispatch.
Installation and training. Our engineers guide installation and train your operators on feeding technique, blade rotation and hydraulic box operation.
Technical documents and machine files are collected under download; machine news and application articles are posted on news. General questions under the FAQ list.
On the published reference unit the lower opening is 650 x 650 mm and supports HDPE pipe up to 630 mm outside diameter. The extended configuration is confirmed up to 800 mm outside diameter at enquiry.
The lower opening accepts whole large diameter pipe, driven in by the conveyor. The upper opening takes shorter offcuts, smaller pipe, purgings and profile scrap, so one machine covers the whole waste stream.
Yes. The machine is built to order against your pipe range. Any size below the confirmed maximum, down to the small offcuts that go through the upper opening, is normal work for this crusher.
Yes. The extended configuration accepts HDPE, PP and PE pipe up to 800 mm outside diameter, and the material and wall thickness are confirmed on the order specification.
Wall thickness drives blade geometry and drive sizing. The published reference unit is sized for thick wall HDPE with a 185 kW drive; your thickest wall is confirmed against the configuration at enquiry.
If the pipe is too large for a standard blade crusher opening and pre-cutting is the bottleneck, the cutterless whole pipe crusher removes that step. For pipe that already fits a conventional opening, a blade crusher may be enough; the choice is confirmed against your pipe data.
Yes. The upper 500 x 500 mm opening takes offcuts, purgings and profile scrap, so the crusher is not limited to large pipe only.
The integrated infeed conveyor, published at 650 mm x 4 m with a 4 kW motor on the reference unit. A full-length pipe is laid on the conveyor and driven into the chamber, so the operator does not push or lift the pipe.
Yes. The machine carries a 1-year warranty with the machine manual, wiring diagram and hydraulic diagram. MOQ is one set, built to your confirmed specification.
No. The extended configuration keeps the cutterless whole pipe infeed of the family, so pipe up to 800 mm outside diameter feeds in without pre-cutting. The capability is confirmed against your pipe before the order is finalised.
Because this machine is built to order, a complete inquiry is what allows an accurate quotation on the first reply. Please include:
Pipe material and diameter range. HDPE, PP or PE, and the largest outside diameter you need to process, whether 800 mm or below.
Pipe wall thickness. The thickest wall you will feed, since this drives blade geometry.
Pipe length. The typical and maximum length, which determines the conveyor arrangement.
Required output. The throughput target for your plant planning; this is confirmed as a project value, not a fixed figure of the standard machine.
Plant information. Available floor area, height clearance in front of the machine, and power supply (voltage, frequency, phase).
Downstream requirement. Whether you need washing, drying, conveying or pelletizing after the crusher, so the whole line can be quoted together.
Commercial expectations. Preferred Incoterm, destination port and required documents.
Site and certification requirements. Whether CE marking or other documentation is required for your market.
What you get back: a written quotation stating the complete configuration for the large diameter pipe crusher, main machine, infeed conveyor, hydraulic box opening, blades and electrical control cabinet, together with the packing plan, delivery schedule and Incoterm. The engineering team confirms that your pipe feeds directly without pre-cutting before the order is finalised.
