Pulverizing Equipment
Wood Grinder
Reduce clean wood pieces and residues with a wood grinder to prepare a more manageable feed for the next biomass or material-processing stage.

Bulky wood residue difficult to handle
Cutting and grinding reduce piece size for onward conveying and storage.
Uneven feed entering a later process
A defined feed opening and discharge arrangement limit the range of material entering and leaving the grinder.
Where It Fits in Your Plant
Wood-processing residues
Reduce suitable clean offcuts and chips before further size classification or biomass preparation.
Biomass feed preparation
Process wood within the machine inlet and tool limits before the next stage. Metal, stone and unsuitable treated wood must be excluded; the grinder does not dry wet wood or produce finished pellets by itself.
How the Wood Grinder Works
A rotating cutting or grinding assembly reduces wood pieces and releases the product through the discharge. Tool geometry, incoming piece dimensions and moisture influence the resulting particle form. Extraction collects dust generated during reduction.
Selection Factors
- Feed opening: incoming piece dimensions must fit the inlet and the specified feeding mechanism.
- Moisture: wet and dry wood differ in cutting behavior, buildup and dust production.
- Foreign objects: metal and stone can damage cutting tools and must be removed from the feed.
Suitable Materials for Crushing
Wood chips
- Material form
- Clean chipped wood
- Typical application
- Reduce chips to a smaller fraction
- Handling considerations
- Moisture, target size and dust extraction
Sawdust agglomerates
- Material form
- Dry loose wood material
- Typical application
- Break larger soft pieces before further processing
- Handling considerations
- Moisture and whether grinding is necessary
Common Issues & Checks
- Uneven particle size: inspect tool wear, discharge condition and changes in feed dimensions.
- Blocked discharge: isolate the machine before clearing buildup or inspecting extraction components.
Operating Precautions
Metal, stone and other foreign objects can damage the tools.

Frequently asked questions
What affects the size of the ground wood?
Tool geometry, discharge arrangement, incoming piece size and moisture affect particle form. Metal and stone must be removed from the feed to protect the grinding tools.
