PVC Pipe Shredder Trial Results: 500 kg/h on 320 mm Pipes, 300 kg/h on 630 mm

When a Chilean PVC pipe manufacturer needed proof that a recycling line could handle real defective pipe, KiTech put its AGR800 system through a live factory trial. The numbers were clear: 500 kg/h on 320 mm pipes and 300 kg/h on 630 mm pipes, both inside the 300–500 kg/h design window. Below we explain what happened, why it matters, and what a PVC pipe shredder can do for a plant that wants to recover its own scrap.

Why Pipe Makers Are Turning to In-House Recycling

A PVC pipe shredder is the centerpiece of any serious pipe recovery line, because PVC pipe production is rarely flawless. Startup scrap, off-spec lengths, and damaged inventory all leave the extrusion line as waste. Today, higher resin prices and tighter waste rules make that choice expensive. A plastic shredding machine built for pipe profiles turns that liability back into reusable flake, cutting raw-material cost and disposal fees at the same time.

This was the Chilean customer's first investment in recycling equipment, timed to a new production line coming online and the urgent need to recover defective pipes.

The Customer and the Challenge

The Chilean customer makes PVC pipes for construction and municipal water projects. The customer's scrap is in-house and relatively clean, which makes it ideal for direct recovery: shred the defective pipe into flake, then pulverize the flake into powder for re-extrusion, and repeat. The output from the PVC pipe shredder moves to pulverizing before returning to production, closing the loop.

From the first needs assessment, KiTech recommended the AGR800 Pipe Shredding System based on the Chilean customer's material profile and processing goals. The Chilean customer wanted measured performance on the exact diameters it runs, not a brochure promise.

How the Trial Was Run

The trial took place at KiTech's facility after production, using the diameters the customer specified:

• 320 mm pipe: 500 kg/h measured throughput
• 630 mm pipe: 300 kg/h measured throughput

Both results sit within the rated design capacity. For a PVC pipe shredder, pipe length and wall thickness matter as much as diameter, and the AGR800 handled wall thickness up to 20 mm and pipe lengths of 6 m. Larger pipes weigh more per piece and are harder to feed, which is why the 630 mm figure is lower — expected, not a limitation. The AGR800 PVC pipe shredder was specified only after these diameters were confirmed against the customer's real scrap, not an estimated average.

A plastic pipes recycling machine like the AGR800 is built around pipe geometry. Long, rigid sections need a different infeed and cutting strategy than bulk film or bottles, and the trial confirmed the system handled the full diameter range without changing the core setup.

Why the Chilean Customer Chose KiTech

The manufacturer compared suppliers from Germany and India before deciding. The choice came down to overall cost-effectiveness, equipment quality, solution fit, and service. From first contact to a signed proforma invoice took about one month; the full cycle through to advance payment took roughly six months.

The deciding factor was evidence. The data came from an on-site factory trial, not a theoretical calculation. When a buyer can watch a PVC pipe shredder process its own pipe sizes and hit the numbers, the specification stops being a promise and becomes a fact. For KiTech, every PVC pipe shredder we deliver is backed by the same kind of measured result. A PVC pipe shredder is only worth importing if the numbers survive a real trial — and these did.

Parameters You Can Verify

For buyers who need to check the claim, the key trial parameters are simple — most are in the table above. Beyond the 320 mm and 630 mm throughput results already shown, the trial also verified:

• Wall thickness: up to 20 mm
• Pipe length: 6 m
• Test material: the customer's own production scrap

Trial videos, on-site photos, and pre-shipment inspection records can be provided on request. Remote video inspection or an on-site trial run can also be arranged, so a prospective buyer never has to take throughput on faith. A PVC pipe shredder running on a buyer's actual scrap turns a capacity claim into proof. That throughput came from a PVC pipe shredder working on genuine production scrap, which is the only condition that counts for capacity planning.

What This Means for Your Plant

If your facility runs PVC or other plastic pipe, the math is straightforward. Every defective length you shred, mill, and reuse is resin you do not buy again. Before choosing a plastic shredding machine, your plant should weigh not just price but uptime, spare parts, and how easily the cutter clears a jam. A well-matched plastic shredding machine pays back through lower material cost and reduced waste handling, and it keeps valuable polymer inside your plant instead of a landfill.

Choosing the right PVC pipe shredder depends on your daily scrap volume and the diameters you actually run. A 320 mm line and a 630 mm line behave differently at the infeed, as the trial showed, so throughput expectations should be set per size. KiTech sizes each PVC pipe shredder to the customer's actual material, which is why the AGR800 hit its targets on both diameters.

A Plastic Pipes Recycling Machine as Part of a Bigger Strategy

Recovering in-house scrap is also a sustainability story. Buyers and regulators increasingly ask where material comes from, and a documented closed loop is a competitive edge in export markets. The AGR800 shows that a focused plastic pipes recycling machine can deliver verified, repeatable throughput — the kind of proof that supports both the balance sheet and the brand.

Because the flake is cleaner and more consistent than mixed post-consumer scrap, the milled powder re-extrudes reliably, strengthening both the cost case and product consistency — and reinforcing the sustainability story.

FAQ

**What pipe diameters can the AGR800 PVC pipe shredder handle?**

The factory trial ran on 320 mm and 630 mm PVC pipes, with wall thickness up to 20 mm and lengths up to 6 m. KiTech sizes each unit to the customer's actual scrap, so other diameters are confirmed in a custom trial rather than guessed from a chart.

**Why run a factory trial before shipping a PVC pipe shredder?**

Throughput depends on diameter, wall thickness, and pipe length — not the nameplate rating. A trial on your own scrap proves the numbers before you import, which is exactly how KiTech validates every PVC pipe shredder it ships.

Getting a Customized Trial

Does your plant have PVC or plastic pipe scrap that needs recovery? Contact KiTech. We evaluate throughput based on your specific material and provide a customized solution and trial arrangement, so you can see real numbers on your own pipe sizes before you commit. A PVC pipe shredder that is sized to your material will outperform a bigger, cheaper unit every time, because throughput follows the material, not the spec sheet.
