FIELD: agricultural mechanical engineering. ^ SUBSTANCE: proposed device includes bin, system of electrodes for forming corona and electrostatic sections of electric field and tray for grain fractions. Device is also provided with grain flow control unit, electromagnet for additional separation of blend mounted in zone of falling of charged grain preliminarily separated by electric field below electrodes creating electrostatic section and electromagnet position regulator. Electromagnet is made in form of separate sections having independent magnetic axes. Electromagnet sections are mounted at shift of their magnetic axes in horizontal plane relative to each other so that direction of electric and magnetic forces acting on freely falling grain should coincide in direction and be maximum. ^ EFFECT: improved quality of separation; increased productivity. ^ 2 cl, 1 dwg |
