A technology is proposed for the separation of particles by shape in a polydisperse granular material using the effects of particle interaction in a fast shear flow on a rough slope. The technology involves the fractionation of the initial mixture by the volume of particles using the segregation effect at the first stage and the calibration of the obtained particle fractions by weight using the effect of quasi-diffusion separation (migration) in the gravity flow at the second. The final stage involves the separation of particles by shape by sieve classification of fractions according to a key geometric parameter.

A description of the functional capabilities of the technology of multifraction separation of particles by density and shape in a polydisperse bulk material is given. The technology assumes a consistent and complex use of the effects of quasi-diffusion separation and segregation of particles in a fast shear flow on a gravity slope, as well as the use of traditional technological methods of particle shape calibration. The assessment of the effectiveness of using of multifraction technology for the production of biologically valuable seed material is given.
