Wood pellet production moves large volumes of material with compressed air and blowers, from raw material conveying through drying, cooling and packaging. The environment is dusty and carries a fire risk, so equipment must be specified for safety as well as performance.
Key applications
- Pneumatic conveying of sawdust and chips
- Drying and cooling air systems
- Dust collection and filter cleaning
- Packaging and bagging lines
- Control and valve actuation
Selection factors
Conveying needs low-pressure, high-volume blowers, while instrument air needs a dry, oil-free supply at low dew point. Heavy-duty intake filtration protects the compressor from wood dust, and spark detection and fire suppression may be required for the conveying system.
Efficiency
Match blowers to the conveying pressure and use variable speed where material flow fluctuates. Dust collection is energy-intensive, so keep filters clean and minimise duct pressure drop to control the plant energy bill.
