Taisho-en soil sifter
« on: May 02, 2012, 10:23 PM »
A mate took a photo of this soil sifter/grader in a green house at the back the Taisho-en.

Does anyone know any companies that make this sort of equipment?

Being in Australia, I've seen mining equipment versions (the size of a house) but not something I could have in the back yard...

Hi Scott,
Yes I saw this also at Taisho en.  However, you can make one (or find someone handy to make one for you).  If you are on Facebook, you can look up Howard Smith of Texas.  He made an excellent one and he has pictures on his FB page of it with a description.  He also has a short video of it working!  We are making one at New England Bonsai Gardens for all the sifting we do to make soil.  We have one large one now, not mechanical, that works fairly well but Howards seems much better than ours.
Good luck,
John Romano

excuse me if im missing something but does the cement mixer sort it into different sizes like the Taisho-en sifter? If not whats the point of going through all of that just to sift out the dust? I think i could manually sift just as fast? But like i said maybe im missing something

I just have sifters with different sizes. And if you don't sift one or two liters at a time, but tens of liters, there is no way you could do as fast by hand.

Alain, I like it. So, you put your material in the mixer, but your small screen on, run it for a few minutes until you stop getting material passing through the screen, tilt it back up, change the screen to the next larger size, empty the wheel barrow, tilt it up and run, repeat for each size that you want. Slick. How many size grades are you splitting in to? dust/fines, 3mm, 5mm, 10mm?

Yes, well it depends on your mixer, I have mixer that will take 15 heaping shovels full for concrete

9 gravel
4 sand
2 cement

So Im thinking close to 150 pounds of material per dump,

Well, according to my experience, dust is not easily sifted at least at soon as there some humidity in the substrate. So I start with the finest screen and water the substrate while running the mixer ( the steel rod is for the hose). I have a well so I am not very concerned by water consumption at least when not in summer. Then I sift from big to small, because it is supposed to be more efficient than the contrary even if one has to load the mixer several times and not just one like with you solution. I sift at 4 and 8 mm.

okay okay I concede that if you sift from small to large and you already have this set-up it would be significantly faster however by the time the average Joe locates a cement mixer and rigs it up i will already have enough soil sifted for a lifetime :)

Um, I sifted 60+ bags of soil components by hand this year, 4 siftings per bag. I need some power sifting to save time.

yeah John I would say of all people that it would be worth the investment it would be you. By the way how many trees do you have potted, Im trying to do the math on how much soil you go through?
