FIELD: agricultural machinery.

SUBSTANCE: invention is intended for mechanized processing of grain crops into mixed fodders, and can be used in farms and individual farms. Device for grain grinding includes a frame with a loading hopper and an electric motor fixed on it, having an opening for grain output, a sieve, a grinder in the form of a plate and a reflector. Fixed sieve is fixed on the bed, on which a rotary sieve which is tightly adjacent to the sieve is installed with the possibility of turning by means of an adjusting thumb-screw, note here that said rotary screen features cylindrical shape and is axially coupled with said screen. Holes on the fixed sieve and the rotary sieve have the same dimensions and arrangement to ensure the possibility of changing the flow section of the holes due to the rotation of the sieve and obtaining different grain grinding.

EFFECT: device for grain grinding allows to obtain different grain grinding without replacement of sieves.
