Hi Mike,

IT  is a very good idea to process the biomass down to a small size before you carbonize it, but it limits the way you make the biochar.

For example sawdust does not have the airflow that can be achieved with wood chips.

So if you use a small particle size of biomass I guess you are restricted to a retort,

 not an issue for me because I use the conservation burn pile method, which my hardwood prunings, from my clients trees, 1-2 inches in diameter, are the perfect size feedstock, Plus I get paid $32 an hour to haul them to my property.

Burning my biomass at both ends,

Paul,


One way to end up with the right size char is to start with the right size wood/biomass..    Spending the time to right size the wood pays benefits on the char side.    Take this wisdom from someone who hammer milled 20 bags of lump charcoal in a garage....    I would have rather hammer milled the wood.....    

my 2 cents

Mike
