I wanted to measure the particle size distribution of my mill and built this gauge. What do you think?

There is an app where you can take a picture with a reference object like penny and it will tell you the distribution.

What grinder are you using?
Even high uniformity grinds should be producing quite a lot of particles below 400µm

Just keep in mind the results will depend on how much sifting has occurred. Some coffee grounds are oblong shaped, so despite being quite large they can fit in a small hole if they happen to pass thru it long ways.

You made the Kruve sifter lol no that’s rad.

Conceptually, I think it’s a better tool than the Kruve sifter in that it gives an instant visual representation of the distribution.

nice!! did you CNC that?

I think this is awesome! Can you do a test using a spinning blade grinder? I would like to show something to someone.
Also worth noting, no matter the grind method, it balances out mostly. Based on particle count and average surface area.

Its a great prototype! I wish we could talk in micron sizes when we discuss grinds. On my Rancillio Rocky grinder I use setting 4 or 5 for espresso and 35 for pour over. It doesn’t really describe the actual size of the particles.
