Who holds how much
· same grounds, four ways to count
Sample
model with fines
real photo, 1,578
the real photo only has coarse particles ≥ 330 µm
Count by
number
surface
volume
available mass
available mass = only the outer 0.1 mm shell
Fines volume share
literature: about 10–29% below 100 µm by volume
Fines peak (volume)
cell size 25–50 µm
Coarse peak (volume)
depends on the grind setting
Smallest size the camera sees
smaller particles drop out of the measurement
