I use my metal screen set quite often for bonsai substrate, both to remove dust and grade the sizes for shohin pots.
Substrate for Pre-bonsai- Do I need to sift potting mix?

I use a screen every spring for soil components that need sifting, mostly my diatomaceous earth. When I sifted the potting mix, I basically lost everything. I guess that might be a good indicator it would not aerate the roots sufficiently.

Loam is a generalized term for soil that is heavy in decomposed organic matter, but sandy and soft. Think of the peat and fine sand mixes used for starting seeds, only more nutrient dense. In the ground it's considered the best sort of soil for growing just about any crop, but the physics of shallow pots means it can stay wet far to long.
Thank you Shady. So it's ok for larger pots...like how big, how deep

It'll work in anything you'd do container gardening with. Impossible to give exact numbers of course.
I'd say anything that could be called laomy would be fine in 5+ gallon container, smaller depending on what you grow in it and watering habits.
Most standard potting soil is made to resemble loam to an extent. If you're thinking of mixing your own you'd get the top soil and add perlite and/or mulch. Those with peat and/or composted manure would also work.

Diatomaceous earth.
Like cat litter. Screen out fines with small screen like window screen size.

Diatomaceous earth. One of the most popular sources for bonsai applications is the NAPA out parts brand oil absorbent, listed as part number 8822.
