Biomass production relies on efficient wood reduction and chip size consistency to maximize energy output. Whether using a biomass wood chipper for fuel or a crane feed wood chipper for large-scale processing, understanding chip size is crucial. This guide explores why chip size matters and how to optimise wood reduction.
Why Chip Size Matters in Biomass
Chip size affects biomass efficiency. Smaller, uniform chips burn better in biomass boilers, while larger chips are suited for bulk heating systems or mulch production.
How Different Wood Chippers Impact Chip Size
Biomass Wood Chippers
Designed for energy production, these chippers produce a consistent chip size to maximise efficiency in biomass boilers. Take the Jensen A425 PTO for example, with its ability to create G30-sized chips, which are ideal for biomass boilers.

Crane Feed Wood Chippers
Handle large volumes of wood, offering customisable chip sizes depending on the end use.

PTO Wood Chippers
Great for landowners managing biomass production on a smaller scale, using tractor power to process wood efficiently.

Choosing the Right Chipper for Biomass Use
- Need uniform small chips? Go for a biomass wood chipper.
- Processing large amounts of wood? Use a crane feed wood chipper.
- Have a tractor? Consider a PTO wood chipper for cost-effective chipping.
Best Practices for Consistent Wood Reduction
- Adjust infeed aperture & throat size for desired chip size
- Regularly maintain blades to ensure sharp, clean cuts
- Use a bespoke wood chipper for specialised biomass needs
The right chipper and chip size can make all the difference in biomass production. Understanding infeed aperture, throat size and wood reduction ensures maximum efficiency and sustainability in your operations.
