Why Is Sawdust Suitable for Making Fuel Pellets?
High calorific value
The calorific value of sawdust varies depending on the kind of wood the sawdust came from. The heating value of softwood sawdust is typically about 20-22 MJ/kg and of hardwood sawdust is about 19-21 MJ/kg. That is to say the calorific value of softwood sawdust is higher than hardwood sawdust, so softwood sawdust is better than hardwood sawdust in terms of sawdust pellet production. Thus if you want to use sawdust pellet mill to make wood pellets, it is suggested to mix the hardwood sawdust with softwood sawdust.
Suitable size for pelletizing directly
Typical size of sawdust is 0.3-2mm in length which is suitable for making pellets by sawdust pellet machine.
Moisture content of sawdust
The moisture content of sawdust is not the same due to the different sources. Sawdust may be of high moisture content from cutting green wood in a sawmill, or very dry from furniture manufacturing. But If wet, you can dry them under the sun or by sawdust drying machine. It is easy to dry sawdust and sawdust with moisture content of about 12%-15% is suitable for feeding into sawdust pellets machine.
