Heavy-Duty Wood Shredder

Product Introduction

Wood waste piles up fast — pallets, offcuts, branches, and demolition timber take up valuable yard space. Manual breaking is slow and dangerous, and standard chippers choke on mixed feed or nails. Every hour your crew spends fighting jams is an hour of lost production.

Meet our Heavy-Duty Wood Shredder, engineered to take on everything from whole pallets with nails and hardwood logs to green branches and sheet material. High-torque, single-shaft shredding action pulls wood in and reduces it to uniform, saleable chips in a single pass. Turn a costly disposal problem into a profitable biomass or recycling stream.

Product Features

Unstoppable High-Torque Shredding A massive gearbox drives a reinforced steel rotor, delivering the brutal low-speed torque needed to crush hardwood, pallets with nails, roots, and sheet materials without breaking a sweat. The slow rotation minimizes dust, sparks, and kickback, creating a safer work environment.

Anti-Jam & Auto-Reverse System We built this shredder for mixed, dirty wood. When a tough object or overload hits, the PLC instantly commands an automatic reverse cycle to clear the obstruction. No manual prying, no bent shafts. The machine resets and resumes feeding in seconds — maximizing uptime on unpredictable feedstock.

Heavy-Duty Blades & Quick Maintenance Blades are precision-forged from high-grade alloy steel and heat-treated for impact resistance. Thicker cutting edges mean more re-sharpening cycles and longer intervals between maintenance. The bolt-on blade design and large access doors allow one operator to service or rotate the entire set in under 30 minutes.

Precise Output Control with Interchangeable Screens Whether you need coarse chips for biomass fuel, fine particles for animal bedding, or uniform pieces for particleboard production, the hydraulic screen lifter makes swapping screens fast and tool-free. Output size ranges from 15mm to 80mm, giving you full command over your end product.

PLC Smart Control & Safety Compliance The digital control system monitors shaft speed, motor temperature, and hydraulic pressure in real time. Emergency stops, interlocked access panels, and a full diagnostic display come standard. Parameter settings can be saved for different materials, allowing one-touch recipe changes.

Applicable Material

Wood Materials We Shred

Pallets & Crates: Whole wooden pallets with nails, shipping crates, cable reels. No need to remove nails — the shredder handles metal fasteners with ease.
Logs & Timber: Hardwood and softwood logs, offcuts, stumps, and timber beams. High torque splits and shreds solid wood without hesitation.
Green Waste & Branches: Tree branches, hedge trimmings, bamboo, and yard waste. Consistently shredded for composting or biomass.
Panel Board & Furniture: Particle board, MDF, plywood, chipboard, and bulky furniture. Reduces voluminous waste to manageable chips.
Demolition Wood: Construction and demolition lumber, floorboards, formwork, and mixed wood waste. Handles contaminated feedstock.
Biomass & Energy Crops: Fast-growing energy crops, miscanthus, straw, and corn stalks. Prepares homogeneous feedstock for gasification or combustion.

FAQ

Can this shredder handle pallets with nails without damaging the blades? Absolutely. The slow-speed, high-torque design manages nails and screws as ductile contaminants. They are sheared off or pressed through without catastrophic blade damage. We recommend a downstream magnetic separator for metal removal after shredding.

What about wet, green wood — will it clog? Our machine handles green wood with up to 60% moisture content. The open rotor design and sized screens prevent wet fines from packing. Consistent feeding with the hydraulic ram ensures steady output.

How often do the blades need to be re-sharpened? For mixed wood with occasional contamination, expect 400–800 working hours between sharpening cycles. Clean, debarked logs can extend this to over 1,000 hours. One blade set accepts 4–6 re-sharpenings.

Can the output size be adjusted for different applications? Yes. The hydraulic screen cradle allows a single operator to swap screens in 10 minutes. We supply a range of screen hole diameters so you can switch from 15mm biomass chips to 60mm coarse mulch.

Do you support overseas installation and training? Yes. We provide comprehensive installation drawings, 3D layout plans, and step-by-step video guidance. On-site commissioning and operator training by our engineers can also be arranged.
