Well-known sieves or woven sieves are used as sifting surfaces, which does not allow for the reliable implementation of the separation process due to the clogging of the sieve openings (sieves) with particles of the material being processed.

Pneumatic separating channels 3 are made with About the waterway 5 and the airway entrance. The separat also contains output pipes for divided sections 7, 8, 9, 10 and guides II.

The speed of movement of the material increases with the increase of the step of the arrangement of the screening surfaces by height and slows down more and more with the increase of the curvature of the concave screening surface, determined by the ratio °r. The angle of the direction of the material flow from one screening surface to another increases with a decrease in the spacing step η of the screening surfaces and an increase in the curvature of the screening surface.

When the value of the excess is 1.4 or less than 0.5, the efficiency of the cutting separator is sharply reduced due to clogging of the gaps between the fingers 13, the jump-like and compacting unstable movement of the bulk material being processed in a zigzag row.

In this case, the proposed placement of additional rows 2 within the height of the main row makes it possible to implement the process of double separation without increasing the height of the separating unit. This possibility is determined by the peculiarity of the gravitational process flowing in a zigzag pattern separation, which consists in the most intense sifting of The sifting of particles is carried out when the processed material moves in a flow of a certain density, when the particles are constrained to a certain degree, excluding their free jump-like movements, which sharply reduce the probability of sifting. In this case, the smaller of the particles are sifted already at 20...30 percent of the sifting surfaces of the zigzag row, while for sufficient completeness of separation of other larger particles, 70...80 percent are required. The percentage of the separating channel.

The sowing surfaces of this row have a sufficiently large gap C between the cantilevered pins 13, which ensures the possibility of grain and smaller impurities entering it, but excludes the possibility of large impurities entering.

In this case, the grain material that has not passed through the first sifting surface I acquires, due to the rational shape (curvature) of the concave sifting surface and the step of their placement along the height, optimal values of speed and direction. meetings with the following seeding surface, ensuring high seeding intensity and self-cleaning of cantilever finger screens.

The sowing surfaces of the 2 additional rows have smaller gaps C between the fingers 13 than those of the main row, allowing small impurities to pass through, but excluding the passage of the main grain.

This material should move downwards according to the sowing news of the first main series. In this case, the zenon passes through none and is excreted through the channels of pure zenon 9, and the solid mixtures disappear from sowing news and 7. is removed from the sepagate after a period of 10.
