ZL-PC600 PET Shredder Machine 15kW 400kg/h Industrial
PET bottle recycling demands a shredder calibrated for the specific density and brittleness of post-consumer PET. The ZL-PC600 PET Shredder Machine is tuned for 400 kg/h PET flake production, with rotor geometry and screen range optimized for clean flake that washes and separates cleanly downstream.

PET has a density of 1.38 g/cc, which is heavier than water (1.0 g/cc) and most other plastics (PE 0.92, PP 0.91, PS 1.05). The ZL-PC600 PET Shredder produces flake at 4-6 mm screen size, which sinks in water-based density separation tanks while PE/PP labels and caps float for removal.
For a 1,000 tonne/year PET recycling line, this density separation efficiency translates to 95-97% pure PET flake output, which commands USD 850-1,100 per tonne in rPET market pricing (vs USD 200-300 per tonne for mixed-plastic bales). The ZL-PC600 PET Shredder is calibrated to maximize this purity, not throughput alone.
The ZL-PC600 PET Shredder integrates directly with downstream wash systems via an optional conveyor (4-meter length, 800 mm belt width). For hot wash systems (80 degC caustic wash), the conveyor delivers pre-crushed flake at a controlled 400 kg/h rate that matches the wash tank residence time of 12 minutes.
For cold wash systems (ambient water + detergent), throughput can increase to 500 kg/h. Cold wash preserves more of the PET intrinsic viscosity (IV), which matters for fiber and strap applications where IV loss reduces mechanical properties. Plants running both applications in parallel typically run two ZL-PC600 machines: one feeding hot wash for food-grade rPET, one feeding cold wash for fiber-grade rPET.
Closed-loop bottle-to-bottle PET recycling recovers approximately 70% of the input material as rPET pellet after sorting, shredding, washing, and extrusion. At a ZL-PC600 throughput of 400 kg/h, the line produces 280 kg/h of food-grade rPET pellet at a conversion cost of approximately USD 0.45 per kg.
For a 4,000 tonne/year bottle-to-bottle line, the annual rPET revenue at USD 1,200/tonne is USD 3.36 million, against a total operating cost of approximately USD 2.0 million (collection USD 600/tonne, conversion USD 450/tonne, overhead USD 250/tonne). Net margin USD 1.36 million gives a payback period of 12-18 months for the full line, of which the ZL-PC600 represents 12-15% of the capital cost.
PVC contamination in PET flake is the single most expensive quality issue in rPET processing. Even 0.5% PVC contamination in food-grade rPET can cause black specks in the final preform, leading to 100% batch rejection at the blow molding stage. The ZL-PC600 PET Shredder uses a 6 mm screen as standard, which produces flake sizes that float-sort effectively to remove PVC cap fragments and label residues.
Plants running bottle-to-bottle food-grade rPET typically add an optical sorter (NIR) downstream of the wash step. The ZL-PC600 output at 6 mm screen size is calibrated to feed directly into NIR sorters without pre-granulation. Plants skipping the NIR step and relying on density separation alone see PVC contamination rates of 50-200 ppm; with NIR, this drops to <5 ppm.
PET is harder and more abrasive than PE/PP due to its higher glass transition temperature (76 degC vs -20 to -10 degC for PE/PP). Running a shredder optimized for PE/PP film through PET service will accelerate blade wear by 3-4x. The ZL-PC600 PET Shredder uses SKD-11 blades with a slightly higher chromium content (12% vs 8% standard) that resists abrasive wear better.
Plants that run mixed PET + PE/PP streams typically use two shredders: a ZL-PC600 PET Shredder for the PET-rich stream and a separate machine for the PE/PP-rich stream. Running both materials through a single PET-tuned shredder reduces blade life to 200-300 hours (vs 600-900 hours for PET-only service), making the two-machine configuration more cost-effective at high throughput.
Q: What screen size is recommended for food-grade rPET?
6 mm screen for hot wash + NIR sorting, 8 mm for cold wash + sink-float separation only. Smaller screens (3-4 mm) produce excessive fines and reduce throughput by 30-40% without quality benefit at food-grade specifications.
Q: Can the machine handle PET trays and clamshells?
Yes, but at reduced throughput (250-300 kg/h). PET trays have lower bulk density than bottles and require different rotor geometry for clean cutting. For high-volume tray recycling, the ZL-PC700 with 22 kW motor and larger feed opening is recommended.
Q: What about PVC label contamination?
PVC labels fragment during shredding and pass through standard screens. They are removed by density separation (PVC sinks, PE labels float) and NIR sorting. The ZL-PC600 output is calibrated for both methods.
Q: Is food-grade rPET FDA-approved?
The ZL-PC600 itself is CE-certified for industrial use. FDA approval applies to the recycling process (wash + extrusion), not the shredder. Most bottle-to-bottle plants use a third-party certification (EFSA in Europe, FDA Letter of Non-Objection in US) for the full process.
Q: How does moisture affect PET shredding?
PET absorbs less than 0.5% moisture, so wet bales from post-consumer collection can be processed directly. Moisture above 5% requires pre-drying to prevent blade sticking and screen clogging. The ZL-PC600 is rated for ambient moisture up to 8%.
