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!
