Quick answer
For wood waste, choose a mobile shredder based on contamination level (nails, stones, wire), the output particle size your end market requires, and wear-part cost — because contaminated demolition wood is abrasive and drives running costs.
Key takeaways
- Match the machine to contamination level: clean pallets and contaminated demolition wood are different jobs.
- Output particle size is set by screen choice and must match the end use — biomass fuel, mulch or further processing.
- Wet green waste shreds differently from dry wood; capacity drops and wrapping risk rises.
- Budget for wear parts: abrasive, gritty wood accelerates cutter and screen wear.
Wood recycling looks simple until the details appear: a shredder that eats clean pallets all day can struggle with dirty demolition wood full of nails and grit. Selection starts with an honest look at the material.
Know your wood waste categories
- Clean wood — pallets, packaging, offcuts. Low contamination, predictable shredding.
- Demolition and construction wood — contains nails, screws, hinges, wire and embedded grit. Needs robust wear protection and magnetic separation.
- Green waste — branches, tops, root material. Wet and stringy; capacity drops and some materials can wrap around shafts.
- Treated wood — painted, coated or preserved material. Some end markets exclude it; confirm local rules for the intended output use.
Start from the end market
The buyer of your chips defines the particle size, and particle size defines your screen configuration:
- Biomass fuel — boilers specify a particle size range and contamination limits; oversized or dirty chips are rejected.
- Mulch and landscaping — more tolerant on size, but metals must still be removed.
- Further processing — board industry feedstock or fuel preparation has its own specification.
Get the end user's written specification before ordering screens.
Configuration essentials for wood
- An overband magnet on the discharge conveyor to pull nails and ferrous fragments.
- Screen selection matched to the required chip size; ask how quickly screens are changed.
- Wear protection in the chamber for gritty demolition wood.
- A hopper sized for your loading machine.
See shredder configuration details for how these components work together, and how to estimate capacity for the difference between wood types.
Site and mobility questions
- Does the wood come to one yard, or does the machine visit demolition sites? See mobile vs stationary.
- Is dust or noise regulated at the site? Ask about suppression options.
- Who loads the machine, and with what machine?

Frequently asked questions
Can a mobile shredder handle wood with nails and screws?
Yes — twin-shaft shredders process nailed wood, and an overband magnet removes the ferrous fragments from the discharged chips.
What chip size can a mobile shredder produce?
Chip size is controlled by the screen or cutter configuration. Select the screen to match the end user specification, whether biomass fuel or mulch.
Can it shred fresh, wet green waste?
Yes, but throughput is lower than for dry wood and stringy material can wrap. Discuss your green waste share with the supplier.
