2. The machine according to claim 1, about tl and h rani and the fact that the electrostatic section of the electrode is made in the form of several plates that are installed with the ability to move one relative to another in the vertical. crops in an electric field. According to the main author. St. No. 784925 is known for electrical cleaning of the cleaning bus, including a feeder, a system of electrodes, one of which is connected to the negative pole and drawn from the corona and electrostatic areas, and the second (settled) to the positive terminal C 1. The disadvantage of the known machine is that almost all conductive and non-conductive particles receive a charge of one sign and separation in an electrostatic field takes place in the field. The aim of the invention is to improve the quality of the separation products. electrode located under the electrostatic section of the electrode connected to the negative pole. In this case, the electrostatic part of the electrode is made in the form of several plates, which are mounted so that they can move one relatively circularly in the vertical and horizontal planes. In addition, an additional corona electrode is installed with the possibility of moving s in a horizontal plane. FIG. 1 shows a principal diagram of the proposed machine with a graphical image of the forces acting on a particle; FIG. 2 is a section -A-A in FIG. 1, (a system of potential electrodes) i in FIG. 3 is a technological separation scheme.

and horizontal planes.

3. The machine according to claim 1, wherein the additional discharge electrode is mounted for movement in a horizontal plane. The machine consists of a feeder 1 with a dielectric charging goat 2, a wire corona-charging electrode 3, which is connected to the negative pole of the plate section 4 of this electrode. Section 4 may be made of two plates moved apart vertically in order to expand the zone of action of the electrostatic force. Under section 4 of the electrode, in the course of the seed movement, an additional charging corona wire electrode 5 is installed. In front of the electrode connected to the negative pole of the voltage source, there is a wire wire connected to the positive pole (precipitator) electrode 6, high voltage source 7. Under the electrodes there is a receiver 8 of separation products with articulated dividers 9.. The machine works as follows. The seed mixture, which has a definite tribozar, from the feeder 1, through the dielectric caplet 2, enters the interelectrode space of the corona discharge field created by the high voltage source 7, between the electrodes connected to different poles. By ionization, the particles acquire a charge, depending on the available tribose charge, size and moisture content of the particles. Under the action of the forces of the field, the particles are directed in the direction of the electrode 6. Next in the direction of movement of the seeds, they fall into a distorted field created by the high voltage source 7 between the deflecting section 4 of the electrode and the electrode 6. Then Particles fall into the zone of action of the additional corona electrode 5, which allows not only preserving, but also replenishing the charge of non-conductive particles that failed to recharge in zone A. A. Particles with lower conductivity, which retained their residual charge, are still recharged. are from the corona electrode 5 and passing through the gaps of the wire electrode 6 are supplied to IV-r receiver section 8. Particles with higher conductivity and relative permittivity declined significantly electrode 4, etc. move between the corona wire T

 x-plebe. 3 714 electrodes 5 and enter the 1st section of the receiver 8. Particles тра whose trajectories towards the potential or precipitation electrodes deviate less, enter the 11th and 111th sections of the receiver 8. Quantitative distribution of particles over sections the receiver is controlled by the position of the dividers 9. Thus, supplying the machine with an additional discharge electrode will improve the quality of the separation.
