Grain Separator

The grain cleaning separator is designed for cleaning grain (wheat, rye, oats, etc.) from impurities that differ from it in geometric dimensions. The separator is installed as part of technological processes in mills, elevators, and cereal plants.

Additional information

The grain separator is used to remove impurities from grain that differ in width and thickness. For this purpose, the separator is equipped with three sieves with apertures of 1.7x20 mm, 4.25x25 mm, and Ø8 mm. The sieves are arranged at an incline and perform reciprocating oscillations.

The separator consists of the following main components: a sieve housing, a receiving box, a vibratory drive, an outlet box, and a frame.

The primary working element of the separator is the sieve frames, arranged in three tiers within the sieve housing.

The top tier of sieves is designed to separate coarse impurities from the grain mass. The middle tier (sorting sieve) removes large impurities from the grain stream.

The bottom tier (undersieve) removes small impurities from the grain stream. The sieve housing is mounted on spring dampers.

The receiving box ensures even distribution of the incoming grain across the width of the sieve. The vibratory drive consists of two counter-rotating electric vibrators that provide reciprocating oscillations.

The outlet box ensures the separate discharge of cleaned grain, coarse impurities, large impurities, and small impurities. The frame serves as the supporting structure for all the components of the separator.
