Substantiation of parameters for a drum with plates to a centrifugal-sieve separator

Numerous studies have proved the high effectiveness of the centrifugal-sieve separation of grain, when the separation of the particles through the separating surface occurs under the action of inertial forces. The work of such sieves in combination with the airflow is one of the ways of intensification of separation. In the presented work, the study of the basic parameters of the inner plate of the drum centrifugal-sieve separator is done. It is shown theoretically and confirmed experimentally the relationship of such parameters as the step of positioning plates, the angle of plate, the total height and the height of the active layer, and the ratio of the angular velocities of the plate and the cylindrical sieve drum. It is established that during operation of the separator in the mode with two pre-treatment units for seeding and grain together with the air passage on the drum plate-seeding unit to be installed radially, and the grain block at an inclination.
