This NutriMill 760200 stainless-steel Microburst milling heads efficiently crush grains. Variable, high-speed mill and texture control helps you achieve precise results, and a grain hopper extension lets you increase the capacity.
It can grind about 3 cups in one minute, very noisy like a jet engine may be, but what do you expect from a 32000 RPM machine, It produces a very fine flour or shall I say powder, yes it pulverizes grains rather than grinding them which I have my reservation about ....But I believe it's still much better choice than buying my own flour from the store, I also use it to grind Fennel seeds, cumin and coriander seeds without any problem.
