The screenless centrifugal fractionation approach is offered for the fractionation of the long-stalked agricultural materials lengthways. The screenless centrifugal fractionation device and its analytical model are described. The basic processes are specified – accelerating particles with the centrifugal disc, spreading in the annular aerodynamic channel, and assorting with the partitioning cylinders. The mathematical simulation of the particle acceleration with the centrifugal disc and the dropped particles motion in the unward airflow processes is carried out. The computer-based experiment is conducted. Paths of particles in the annular aerodynamic channel are obtained. The paths differ so greatly that it is possible to state the separating properties of the centrifugal force field and airflow combination. The recommendations on the arrangement of the partitioning cylinders are given. The simulation results imply the feasibility of assorting the long-stalked materials with the centrifugal tool at the cost of the differences in particle spreading paths in the airflow.
