Abstract

The invention relates to the separation of grain materials and intermediate grinding products according to a complex of physicomechanical properties and may find application in the grain processing industry and agricultural production. The purpose of the invention is to increase the degree of separation. The grain-grain flow is pre-directed onto the conical surface of the rotating impermeable nozzle, after which it is introduced into the annular space between the rotating in the opposite sides of the cylindrical shell and the cylinder coaxially installed inside it with the nozzle fixed on it, with an average circumferential rotational speed of the impermeable nozzle exceeding the speed her grain air flow 1.5-2 times.

On the other hand, it is inexpedient and unlimited to increase this indicator, since, however, when it reaches a certain value, not only does the growth of the degree of division stop, but there is a tendency towards its importance. The ego is explained by heme, which is significant, by increasing the average peripheral speed of the lower nozzle, i.e., when it is already more than two times larger than cK (.) K), and there is a partial slip of grain. The moment of their contact with the side surface of the lower hull, and this leads to a decrease in the intensity of the duck nose and, as a result, a decrease in the degree of separation.
