I built my sieves to so they would nest and fit into a large plastic mortar tray. I set the tray on bench at a convenient height, stack up the desired sieves, and slide it back and forth. The tray slides fairly well on the bench as-is, but I am going to make a couple of slippery rails from cheap HDPE (high density polyethene) cutting board so it slides even better. My sieves are made from 1/2" = 13 mm, 1/3" = 9 mm, 1/4" = 6 mm, 1/8" = 3 mm wire mesh and 1/16" = 1 mm window screen. The window screen has a layer of 1/2" wire mesh under it for support.
You want a large area to sieve so that the final loading on the screen is only 1-1.5 particles thick. Otherwise you get some of the smaller particles trapped above the screen and they don’t fall through unless you sieve for a very long time. The screens on mine are about 15" (38 cm) by 30" (76 cm). A smaller mortar box is readily available in the US which could also be used. I included handles so that they could be used to sieve materials in the field - bulk lava or pumice to get rid of the oversized or my garden solid to remove rocks.
This is the same concept as Soil Sifter that Bonsai Mirai sells - https://goods.bonsaimirai.com/collections/bonsai-essentials/products/needs-weight-soil-sifter - but a bit smaller and a bit more portable.
