Abstract

The invention is suited to magnetic separation and can be used in the mining and other industries. The purpose of the invention is to increase the efficiency of extraction of small metals. The separator contains an electromagnetic system with ferromagnetic plates 6, immersed in the flow 8 of the source material. Plates 6 are serrated. with U-shaped slots and mounted at a certain angle to the longitudinal axis of the transporting body 7 with the possibility of movement in the vertical and horizontal planes. Transported by the authority 7 stream 8 of the material; The plates are removed 6. During the movement of the conveyor, under the poles of the separator, the particles of the separated flow pass through local areas of a highly interesting and high-gradient magnetic field, mecha-. It is physically in contact with the teeth immersed in the flow 8 of the plates 6. As a result, ferromagnetic inclusions vigorously stick to the teeth of the plates 6. The H-shaped grooves additionally contribute to the flow 8 in the working area of the separator. 3 il. v; : C h 0ЈE5В1

Coils 2 are connected to a source of direct current, as a result of which a magnetic field is created in the interpolar volume of the electromagnet, under the action of which additional poles

At the same time, due to the toothed shape of the plates, the working area of the steel section is always much more (practically 2-2.5 times) along the flow path at the base of the plates than the total working area of the tooth section, due to which the steel of the teeth is highly saturated and the magnetic induction in the steel of the teeth in the operating mode is practically 2, 4 T. As a result, in the area of placement of the tooth

The plates of the 6-plates create local areas of a high-intensity and high-gradient magnetic field, sufficient to extract small metal inclusions with a particle size of 0.05 mm and above. -. . -. . .. .-. . ;

Due to the installation of plates 6 -: at an angle to the longitudinal axis of the poles (Fig. 2), the particles of the separated flow in the period of movement of the conveyor 1 by the separator poles (in the direction of the arrow C, Fig. 3 orthogonal to the longitudinal axis of the poles) inevitably: pass through local areas of the high, high intensity and high gradient magnetic field, mechanically contacting with the teeth immersed in the flow; 8 plates 6, as a result of which an intense ferromagnetic metal effect on the teeth occurs. : plates 6, while non-magnetic particles of material 8 almost freely pass between the plates 6.; The implementation of the plates 6 with different grooves additionally contributes to the free passage of the stream 8 in the working area of the separator. ,;

As the ferromagnetic metal inclusions accumulate on the teeth of the plates 6, the extracted metal inclusions are periodically unloaded. For this purpose, the coils 2 are disconnected from the network, after which the additional poles, 5, together with the plates 6 and the metal switches sticking to them, are manually removed from the pole-zone of the separator and cleaned from adhering metal connections, for example, with a brush or waste water (during this period, it is desirable to stop the area of the separated material on the conveyor belt 7 and stop the conveyor) „.h

After unloading the recovered metal connections, the additional poles 5 together with the plates 6 are re-installed under the poles of the separator, the coils 2 are again connected to the direct current network and the process is repeated.
