1 – sieves or the traditional execution;
2 – Fadeev sieve
Now, when the high technology allows to accomplish wonders with metal, it is time to turn to sieves and screens for cleaning and grading of grain which we have made. We have patented the sieves with hexagonal holes, which in case of replacement of round-hole sieve, sufficiently increase productivity of any equipment for grain cleaning.
The matter is that the form itself of a round hole in conventional sieves, even with a small brace between holes, does not allow providing the max possible clear area due to “stars” remaining between holes. Quite another matter with hexagonal holes.
Fadeev sieve produces LTD “ZEO Sokol” (Kharkov) under a license agreement.
The average values of effectiveness during replacement of conventional round-hole sieves for Fadeev sieve are presented in comparison diagram.
THE PRESENT DAY FADEEV`S SIEVES ARE PRODUCED WITH SIZES FROM 1.5 MM TO 4.0 MM AT A PITCH OF 0. 5 MM, FROM 4.0 MM TO 10.0 MM AT A PITCH 1.0 MM.

LTD “Factory “Fadeev Agro” produces hexagonal sieves for grain cleaners of any national and foreign producer. The size “a” is set depending on the size of seed grains and performance targets.
Implementation examples of such sieves for the grain cleaners of different manufacturers are presented below.
