A comprehensive analysis reveals that the post-grinding coffee particles primarily fall within the [20 μm, 1500 μm] range. Moreover, as the blade setting escalates, the cumulative particle size distribution curve for sizes above 100 μm demonstrates a shift towards larger particle sizes. This indicates that an increase in the blade setting ...

As with sandpaper, a smaller number signifies the abrasive particles are larger. RELATING GRIT TO SIZE. Grit numbers are derived from mesh sizes, mesh being the standard way of grading powder. The general principle is that of sieving: the finer the mesh the smaller a particle must be to pass through the gaps between the wires.
