Grinding: Particle Size and Extraction - COFFEE IQ

Particles from 1 to 1,500 microns are produced in different sizes: particles below 100 microns, around 400 microns and larger than 800 microns. A grinder can never produce 100% of particles of the same size, but they are more or less accommodated in a few micron ranges. This is called grind distribution.
