In cobers, the area of material separation is magnetic and can be used in mineral processing plants processing magnetite ores.

The purpose of the invention is to increase the yield of the concentrate by creating a pulsating magnetic field in the area where the pulp is introduced into the bath.

FIG. 1. image separator, cross section; in fig. 2 - enlarged view of the node of the loading channel of the bath and the magnetic system above it.

The magnetic separator includes a non-magnetic drum 1, a magnetic system 2 located in the zone of tailings separation, a magnetic system 3 located in the zone of concentrate separation, both magnetic systems made in the form of a rm 4 with permanent magnets 5 fixed on it, an additional magnetic system made in the form of magnetic dipoles 6 installed on the frame 4 with the possibility of rotation over the loading opening 7 in the bottom of the antenna 8, the feeder 9 and the receivers 10 and 11 of the separation products. The additional magnetic system is installed so that the axes of rotation of the drum 1 and magnetic dipoles 6 lie in a vertical plane passing through the middle of the charging station. Hole 7 in the bottom of the bath 8.

The magnetic separator works as follows. .

In the gap between the bath 6 and the surface of the immagtic drum 1, the rotation of the magnetic dipoles 6 creates a pulsating-pulsating and rotating magnetic field of the dominant frequency, under the influence of which the magnetic particles come into rotational motion and, moving and the volume of the pulp, receive On the surface of the pemagpit drum I above the loading opening 7 (Fig. 2), where they continue to rotate around their gravity, under the influence of the chain of rotation of the rotation chain, more selective flocculation and separation takes place. and framed in the pachalny period of the process. The magnetic part of the material is pulsed with a pulsed and sepa- rated pesaiMe and is moved to the area of the comic-throne deletion, where it is sent to the position of the non-magnetic drum 1 and is carried to the receiver 10. The transport of the end of the waste in the magnetic field of the magnetic field 5 More favored is the emergence of a co-graft output, and the primary phase mode selectively with pulses and separations in a pulsating-pulsating magnetic field increases the frequency of scattering, which, in aggregate, soparaschEI process.

The non-magnetic part of the material is self-. the current moves to receiver 11.
