What mesh size and material works best for DIY soil screening?
A welded mesh panel with 12 × 12 mm openings made from Ø1 mm wire balances flow and stone retention for typical garden soil [Elektroda, Magister_123, post #16604478]
Rotary sieve for DIY soil.
TL;DR
- A rotary soil sieve was built for backyard earthworks to remove stones from the ground.
- The frame uses 40-angle bar, with a welded-mesh screen mounted on bicycle rims and driven by a 3/4-inch shaft on two bearings.
- The screen measures 1x2 m with 12x12 mm mesh made of 1 mm wire, and an old concrete mixer motor powers it.
- The motor is about 500 W and 1420 rpm, while the sieve itself runs at approximately 50 rpm.
- It reportedly met 100% of the design requirements and cost no more than 200 zł.

Hello.
Due to backyard earthworks and a lot of stone in the ground, the need to build a sifter arose. The inspiration came from youtube videos.
The frame was made of angle bar 40. The screen proper was made of welded mesh (1x2m) with 12x12mm meshes made of 1mm wire. The mesh was fixed to the bicycle rims (62cm inside). The shaft is a 3/4 inch tube mounted on 2 bearings, ''spokes'' made of 6mm wire. Motor from an old concrete mixer of about 500W 1420rpm.
The sieve rotates at approximately 50 rpm. At higher speeds, the centrifugal force is too great and the soil 'sticks' to the screen.
The whole thing may not look like much, but it meets 100% of the design requirements. The cost of construction, due to some elements, did not exceed 200zł.

Cool, simple design :D . That I would make some "hopper" to pour "material" from the front :idea: and covers for these gears, because "he doesn't sleep badly". [Read more]
Replace the engine fan housing. [Read more]
I thought about it too but due to material shortages I abandoned the idea. After a few tons of shifted soil I can safely say that it is better without a hopper. Maybe it would look nice but the shovel... [Read more]
And how will the shoulder blade break off and hit someone? And this may not be difficult. [Read more]
Why such a large distance from the front of the frame to the drum? You can see that because of this the axle bends when throwing soil. A cover from above would be useful, because a lot of soil flies... [Read more]
The aforementioned funnel (chute) was supposed to be there. But as I wrote earlier: I would have to lift each chute with soil about 30cm higher and this is really a lot when loading manually. Secondly,... [Read more]
I have a question - did you try to screen the aggregate there? Would the construction stand to screen such material? I mean personal conviction - because I am thinking of such a design with the difference... [Read more]
@beretus Personally, aggregate was not sifted because I did not have such assumptions during the construction. I think that the sieve can handle it provided you make a funnel with a regulating slide.... [Read more]
And as the mesh was attached to the wheel because for welding it is probably too thin [Read more]
Ordinary wire for reinforcements. [Read more]
A little expensive piece of sheet metal just around the fan will improve cooling. On the front you can put a piece of mesh even of plastic. And what kind of colleague does anarchism write? This... [Read more]
It took me a while but finally I assembled my drum screen. The assumptions were similar except that I did not want to have an axis throughout the entire length of the drum. Short description: The motor... [Read more]
What is a net? Where do you buy one? [Read more]
In my humble opinion, there should be a hopper and, in addition, a rim - a bank a few centimetres high to prevent the backfilled soil from escaping from the drum. The hopper has the advantage that the... [Read more]
