The narrower the screen range, to a small extent you get higher void space and thus lower overall density. My meshes are 15 (kitchen sieve), 20, 40, 60, 100. I need to get a 30 and a 50 to make the duplicate size ranges to commercial.Quote:
I also did some more screening. to only gather the grains between 30 and 40 mesh. This isn't to far from the mark after all, if I push it up slightly from 1.64 density to 1.7 I might be there...then again, maybe this is where I want to be.
To try and raise the bulk density I took my 20#-40# fraction, scooped a bit off the 60# (maybe 10%) and add it back to simulate a 20#-50# range of FFFg.
