Combine settings in spring barley

[Elj]

Hi,
Combining s/barley this afternoon, with a lexion 600, tried everything we can think of, but we are still losing to much barley over the back, would anyone share their settings, so that we can have better go of it tomorrow,
Thankyou
Elj

Over the back from where? Rotors or sieves??

 

[Elj]

Sieves, even with the bomb doors closed.

Too much going through returns? Overloading the top sieve. Try turning up the wind unless it is a very poor sample. In which case wind may be too high
Also open bottom sieve

Slow rotors, open concave, slow drum, more wind, open sieves.
