Increasing biochar surface area: Optimization of ball ...
Additionally, the method of salt-assisted dry-milling was tested and found to increase both the total and micropore surface areas of biochar, but not as effectively as wet-milling methods. For salt-assisted milling, a 50:1 mass ratio of YSZ grinding media:NaCl was optimal for maximizing both the total and micropore surface areas of the biochar.

Design and Fabrication of a Simple Laboratory Ball
2018-12-3 The fabricated ball mill was tested to 1 mm, 10 mm and 1-10 mm of coconut shell chips for three series of testing to evaluate the grinding capability and reproducibility. For 30 minutes of testing, the ball mill has produce the powder coconut shell about (26.07 ± 1.2) %; (22.69 ± 1.58) % and (16.24 ± 0.52) % respectively for 1 mm, 10 mm and 1-10 mm of coconut shell chips.

Small production scale: I would buy an old farm grinder-mixer. It was made to grind corn and other feedstuffs and mix them together. It has a large hammer mill WITH BUILT IN DUST MANAGEMENT!! It also would let you mix biochar and other amendments (green sand, azomite, alfalfa pellets, bone, blood, or feather meal, etc) in at the same time.

Advice on Crushing Biochar (biochar forum at permies)
Why four months? Sawdust is a pre ground feedstock that could be used. Ground biochar would blow away very quickly if driven over daily. When charcoal is ground in a ball mill to make gun powder, it is processed until it reaches a fineness called "air float". I think we want to stop long before that point. Large quantities could go into pond ...

2020-1-1 Gupta S. et al. (2018) used biochar derived from mixed food waste, rice and wood waste as carbon sequestering additive in mortar, obtaining similar results in mechanical strength by adding 1–2 wt% of biochar compared to control mix. Also, an increase of more than 20% in compressive and tensile strength was reached.

Why Agglomerate Powder? - FEECO
A lack of flowability is one of the most common reasons for which producers decide to agglomerate a powdered material or product. The rheology of powders, while varying from one material to the next, makes powder generally less flowable than a granular product. When powder is agglomerated, however, particularly by wet granulation (also known as ...
