The tangent, carried out to section 4 Ж 2 from its end section, is located at an angle of 10-40 ° to

horizontal plane. The mixture from B enters into Ж 2 and gets into the zone of action of the magnetic field created by And 5, under the action of which eddy currents are induced in the electrically conductive particles. The magnetic field of the latter interacts with the magnetic field I 5. Under the influence of the resulting electrodynamic force, the particles measure the trajectory of movement along Ж 2 and enter the corresponding unloading chamber B. 1 з, п. f-ly, 2 pcs.

The purpose of the invention is to increase the separation efficiency and reduce the efficiency: cost savings.

I FIG. 1 shows a separator, front view; in fig. 2 - the same, a side view i Separator contains a loading buffer 15 transporting devices in the form of a curvilinear trench 2 with a curved-concave gun at parts 3 and 4 ,,: filled from a dielectric ma- teri: material.

The chute is located at an angle of 10 - 40 ° to the horizontal plane, which allows you to adjust the speed of movement of the source material. The inductor 5 of the traveling magnetic field is in the form of a roller with grooves 6 on the surface, with the grooves made at an angle of 35-45 ° to the axis of rotation of the roller, and is located under the curved section of the iron line. The slots contain permanent mag1-pins with alternating polarity. The receiving bunker consists of two chambers. Chamber 7 is designed for electrically conductive particles, and chamber 8 is for electrically non-conductive particles “Under the hopper 1 there is a concave gutter area.

The inductor is driven into rotation in any known manner, for example by an electric motor. The separable mixture is fed from the hopper 1 to the Curved Chute 2 and then to the magnetic field, which is created by a rotating roller. Under

the magnetic field in electrically conductive particles induces eddy currents.

I

As a result of the interaction of the rotating magnetic field - with the magnetic field of the eddy currents, an electrodynamic force F arises, directed perpendicular to the installed magnets. The force F depends on the particle mass and acceleration with which the particle moves. The resultant force F Fg + F determines the trajectory of the conductive particle. Thus, electrically conductive particles change the trajectory of movement along a curved chute and enter the chamber 7. Non-conductive particles, which are not affected by the magnetic field, are burned into chamber 8,
