The Solution of the Problem of Separating a Mixture of Polydisperse Particles of Different Shapes

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.
