Efficient Wood Crusher for Sawdust, Chips & Shavings

Wood crusher, also known as a wood chipper or shredder, uses a high speed blade system to process logs, branches, and wood waste into uniform chips or powder. It is widely used in biomass energy processing, landscaping applications, and wood recycling projects.

After logs enter the feed inlet, they are first cut by high-speed blades, then pass into the crushing chamber for further crushing by hammers.

The screen controls the discharge size. Material that meets the required size is discharged, while oversized material continues to be crushed.

Without a screen installed, the output is typically wood shavings.

The machine supports electric and diesel drive options to suit different power conditions, with an optional tractor PTO for easy mobility and on-site operation.

Common Materials Processed

Logs and wood blocks
Wood board offcuts
Branches and forestry waste
Used wooden pallets and packing wood

For board waste and other non-branch materials, a larger feed inlet can be added. The material feeds directly into the hammer crushing area for efficient processing.

FAQ?

Does moisture content affect crushing performance?

Yes. The recommended moisture content of raw materials is 15% to 30%. Excessive moisture can reduce crushing efficiency and increase machine load as well as wear on wearing parts.

How to adjust the final particle size?

The size can be changed by replacing the screen. We offer multiple options from 3 to 50 mm. Additional screens can be purchased to meet different production needs.

How often should blades and hammers be replaced?

Alloy blades can be resharpened 2–3 times, lasting about 3–6 months under normal use. Hammer life depends on material type and working hours, usually replaced every 4–8 months.

Is there much dust during operation?

Some dust will be produced. A dust collection system (bag filter or or a cyclone with a rotary discharge) can be added to reduce dust, keep the workspace clean, and extend equipment life.
