Grain cleaner using Kongskilde blower

Made a zigzag sorter from 1.5mm galvanised sheet to clean some grain. We had a farmking rotor sorter but the weld mesh sieves gave up and it never did a great job in any case. The grain blower pulls the light stuff through and lets the clean heavier grain fall through the zigzag sorter.

Varying the pull flow varies how hard it sorts. Higher flow means more good grain gets rejected but even less chaff in sample.

Pretty happy with results. It's only a rough test rig just now but I think it's doing about 3t an hour based on augur size. Also breathes some life into the blower as it wasn't getting used much...

Horrible welds on the galvanised sheet so ignore those!

 
Looking to build one to screen weeds from durum, I already have a kongslide, any specific zig zag pattern you could recommend?
I looked at some research papers and some commercial examples as a basis, but it's been a while since I used it to be honest as I made a two sieve vibrating cleaner that gets rid of more of the charlock pods that the zigzag cleaner wasn't separating. I think it has 6 or 7 zigzags and the feed in was at the 3rd zigzag. The cross sectional area was equivalent to the blower pipe or there abouts.
 
Isn't that the dust aspirator? I wonder how much that would cost? Mine cost me a sheet of galvanised and a bit of time... Also I don't have 3ph in that shed and most of these type of cleaners have fans that need a 3ph supply...

Would probably just suck out dust but might do small seeds as the grain is in freefall but isn't that what the zig zag does.
Would have thought the fan you are using would do the job. No idea on price.

Thanks, I started making one out of old closet doors yesterday, durum is heavy kotia weeds are light, hopefully it's not to much volume.
