Heavy-Duty Plastic Pallet Shredder

Product Introduction

Broken plastic pallets, rejected crates, and scrap HDPE containers pile up fast. They’re big, thick-walled, and expensive to haul — and they’re almost impossible to process with standard granulators, which stall on massive chunks or demand labor-intensive pre-cutting. Landfill costs are rising, and you’re sitting on thousands of kilograms of perfectly recyclable polymer. You need a shredder that can swallow an entire pallet and spit out saleable regrind in one step.

Our Heavy-Duty Twin-Shaft Plastic Pallet Shredder is engineered for this exact job. With extreme low-speed torque and aggressive shear blades, it grabs whole HDPE, PP, and mixed plastic pallets — occasional nails, metal inserts, and all — and reduces them to uniform, easy-to-handle chips without stalling, wrapping, or melting. The output is ready for granulation, direct washing, or sale as clean recycled flake. Turn a costly, space-consuming waste problem into a profitable recycling stream.

Product Features

Twin-Shaft, High-Torque Shredding for Thick-Walled Plastics Two counter-rotating shafts drive massive, through-hardened alloy blades at low speed (12–25 rpm). The immense torque tears through heavy-gauge HDPE and PP pallets, structural ribs, and solid corners without hesitation. Unlike high-speed grinders that skate over hard surfaces and overheat, our shearing action bites in and cuts cleanly.

Anti-Jam Intelligence & Auto-Reverse The integrated PLC continuously monitors shaft load. When a particularly thick solid block, metal insert, or tramp object is encountered, the rotors instantly auto-reverse to eject it and automatically resume forward rotation. No operator intervention, no bent shafts, no hours of downtime prying out stuck pieces.

Heavy-Duty, Re-Sharpenable Blades Blades are precision-machined from high-carbon, high-chromium tool steel (D2/SKD-11 equivalent) and through-hardened for maximum toughness. Plastic pallets are relatively soft, so blade life is long — but when wear does occur, the thick cutting edges can be re-sharpened multiple times. The segmental bolt-on design allows fast rotation or replacement by one operator.

Adjustable Output Size with Quick-Change Screens A hydraulic screen lifter enables fast, tool-free screen changes. Whether you need coarse 40–60mm chips for transport or fine 15–25mm regrind for direct granulation, you can dial in the exact output dimension that matches your downstream process. One machine serves multiple product specifications.

Safe, Low-Speed Operation & Dust Control The extremely low rotor speed eliminates spark generation and minimizes dust, making the process inherently safe for plastic handling. Optional integrated dust extraction keeps your workplace clean. Full safety interlocks and emergency stops protect your operators at all times.

Applicable Material

Plastic Pallet Materials We Shred

HDPE Pallets: Heavy-duty, thick-walled high-density polyethylene pallets used in logistics, food processing, and pharmaceutical industries. Shredded into uniform chips for washing and pelletizing.
PP Pallets: Polypropylene pallets with high rigidity and chemical resistance. High torque shears through solid corners and structural ribbing without stalling.
Nestable & Stackable Pallets: Lightweight, thin-walled nestable pallets and heavy-duty stackable pallets. One machine handles both extremes of wall thickness.
Plastic Crates & Totes: Bottle crates, fish boxes, logistics totes, and dairy crates. Processed alongside pallets without adjustment.
Plastic Drums & IBC Components: HDPE drums, large containers, and IBC cages (plastic portion). Shredded for volume reduction before washing and regranulation.
Reinforced & Contaminated Plastic Pallet Waste: Pallets with metal reinforcements, nails, glass fillers, or embedded RFID tags. Low-speed shearing handles these inclusions; metals can be removed downstream magnetically.

FAQ

Can the shredder handle a whole plastic pallet without pre-cutting? Yes. Our larger models (PLTSH-800 and above) are designed to accept standard 1200×1000mm and 48×40 inch plastic pallets directly, thanks to the wide chamber opening and powerful hydraulic ram. Some oversize pallets may require simple pre-cutting, which we can advise on.

What about metal inserts, nails, or RFID tags in pallets? The low-speed shearing action handles small metal inclusions without blade damage. Metal fragments are cut and discharged with the plastic chips. We recommend a downstream magnetic separator to cleanly extract metals, leaving pure plastic regrind.

Will the plastic melt or gum up the blades? No. The ultra-low rotor speed (12–25 rpm) generates negligible frictional heat. Plastic is sheared cold, producing clean-cut chips with no melted edges, no sticky residue, and no blocked screens.

What particle size is best for selling recycled plastic from pallets? For granulator feed, 15–25mm chips are ideal. For bulk transport to recyclers, 40–60mm coarse shred is standard. Our interchangeable screens let you switch between sizes in under 10 minutes.

How long do blades last when shredding plastic pallets? HDPE and PP are relatively soft and non-abrasive. Typical blade re-sharpening intervals are 1,000–1,500 working hours for clean pallets. One set of blades can be re-sharpened 5–7 times, offering excellent long-term economy.

Can you supply a complete line from pallet to washed, clean regrind? Absolutely. We provide complete systems: shredder → conveyor → magnetic separator → granulator → washing line → clean flake. Full engineering, installation support, and operator training are included.
