APPARATUS FOR SEPARATING LIGHT BULK MIXTURES Russian patent published in 2002 - IPC

FIELD: agriculture. SUBSTANCE: apparatus has flat electrodes arranged one above another at an angle one with respect to the other so that electrode spacing may be adjusted in the course of flow of material to be separated. Upper electrode lower surface is covered with dielectric. Lower electrode is arranged at an angle to horizontal plane, with electrode spacing reducing in the course of flow of material, and is overlapped with current-conductive conveyor belt extending transverse to lower electrode and arranged at the same angle to horizontal plane. Electrode with dielectric layer is located above conveyor for charging material to be separated. Apparatus may be used for separating seed mixtures due to electric properties of mixture components in electrostatic field. EFFECT: increased efficiency and improved quality of separated material. 2 dwg
