The process
Veneer dryers, sanders and saws produce wood dust that is extracted to cyclones and bag filters, and the dryers and boilers burn the waste. Combustible dust, so spark resistant construction on the extraction side.
The gas
Fibrous or stringy material that wraps a shrouded wheel. An open or straight radial impeller, spark resistant where the fibre is combustible, placed before or after the collector as the material allows.
Selection for this process
| Role | Primary collector where the particle size is coarse enough |
| Construction | Mild steel or stainless steel |
| Discharge | Hopper with rotary air lock valve |
