Thank you to all who responded to my question.
Kelley: The sieve set I want is exactly like the stone set Rio sells
but I need smaller sizes. The Rio set screens 0.9mm to 4.5mm. I need
sizes from 0.2mm to 0.9mm. Maybe Rio could find out if this company
either has or would be willing to make sizes under 1mm.
Jesse: As you indicated in your post www.mcmaster.com has a variety
of mesh sizes but the minimum order is 24" X 48" per size. The total
price is quite high unless you are buying for a very large number of
Ellen: www.twpinc.com does have mesh but the $150 minimum stopped
me. I will be trying to melt the mesh as you indicated into the
stacked plastic cups suggested by Brian.
Dave: As you indicated, www.mscdirect.com has various sizes of metal
screens in 12" X 12’ pieces. I located mesh sizes (width opening
converted from inches) 0.20mm, 0.38mm, 0.045mm, 0.55mm, 0.65mm,
0.73mm, 0.86mm, 1.32mm, 1.9mm. Not exactly even numbers but it is
more important for the granules to be the same size than an even mm
size. Very nice company, fast service, good packaging. The total
price came to $93 so it would be helpful if you have 29 friends to
split the cost.
Brian: Thank you for your excellent instructions for making a
stacked granulation sieve.
Again, thank you for your help.
