DEVICE FOR SEPARATION OF MIXTURES Russian patent published in 2001 - IPC

FIELD: devices for separation of mixtures according to size of particles into two fractions, final grinding of coarse particles to passable sizes; grinding raw materials for formula feed. SUBSTANCE: proposed device includes loading branch pipe and bladed disk located under it. Blades are fitted on both sides of disk. Inner and outer chambers located coaxially relative to disk are provided with openings for escape of products. Calibration grate is fitted above disk for axial motion forming calibration slot between bladed disk and calibration grate. Part of calibration surface of grate is made in form of truncated cone. EFFECT: enhanced efficiency of separation; increased output of fine fraction of various size. 5 cl, 3 dwg
