Classification of sawdust

Sawdust can be broadly classified based on size, moisture content, and source of wood.

1. Size: Sawdust can be categorized based on the size of the wood particles. Fine sawdust is smaller in size compared to coarse sawdust.

2. Moisture content: Sawdust can also be classified based on moisture content. Green sawdust is freshly cut and has a high moisture content, while dry sawdust has a lower moisture content and is usually a byproduct of seasoned or kiln-dried wood.

3. Source of wood: Sawdust can be classified based on the source of the wood. Hardwood sawdust comes from hardwood trees such as oak, maple, and cherry, while softwood sawdust comes from softwood trees such as pine, spruce, and fir.

Overall, the classification of sawdust is important as it affects its suitability for different applications such as animal bedding, wood fuel, and composite materials.
