Abstract

The invention relates to magnetic enrichment and makes it possible to increase the efficiency of the separation process by increasing the strength of the magnetic field above the surface of the yarn drum (B) 1, which is the working body. Inside it there is a magnetic system, made up of permanent magnets (PM) 3 mounted on the rome 2. Their poles of the same name are facing the surface B 1. Ferrous magnetic plates 4 are installed radially to the surface B 1 on the pole 2. Their ends facing the surface with Magnetic product (L IND with 4 CO 00 Non-magnetic 1 and producgg figure 1

Description

B 1, made ribbed. Between the plates 4 and PM 3 additional PM 5 in the form of wedges are installed. The side surfaces of PM 5 have a pole similar to those of PM 3 facing the surface B 1. The initial mixture is fed by the feeder 6 in an even layer onto the surface B 1, to the zone with increased magnetic field strength above the ribbed surface of the plate 4.

The invention relates to magnetic enrichment and can be used in the mining industry of the national economy.

The purpose of the invention is to increase the efficiency of the separation process by increasing the magnetic field strength above the drum surface;

Figure 1 shows a drum magnetic separator, a cross-section; figure 2 - the implementation of the magnetic system.

The drum magnetic separator contains a working body in the form of a non-magnetic drum 1, inside which a magnetic system is installed, made up of blocks of the main permanent magnets 3, mounted on the frame 2. The blocks of permanent magnets 3 face the surface of the drum with the same poles. Ferromagnetic plates 4 are placed radially to the surface of the nonmagnetic drum 1 between the blocks of permanent magnets 3 on the frame 2, and additional permanent magnets 5 are installed between the blocks of permanent magnets 3 and ferromagnetic plates 4, and the side surfaces of the additional magnets have wedges the same pole with the combinable surface of the blocks of permanent magnets 3 and ferromagnetic plates 4.

The ends of the ferromagnetic plates 4, emerging on the surface of the drum I, are ribbed. The drum magnetic separator also contains a feeder 6 and receivers 7 of separation products.

The device works as follows.

The non-magnetic material of the fuzzy force of pemtropulary forces is separated from B 1 and unloaded into one of the receivers 7. The magnetic material is pressed against the surface B 1, transported to the unloading zone of the magnetic product, where from B 1 and is discharged to another receiver 7. 1 c.p. f-ly 2 ill.

The initial mixture of materials is fed by the feeder 6 in an even layer onto the surface of the non-magnetic drum 1 into the zone with a magnetic field strength above the ribbed surface of the ferromagnetic plate 4. The non-magnetic material separates from the drum 1 when in contact with the drum 1

and is discharged to receiver 7 for a non-magnetic product. The magnetic material is due to magnetic forces arising in a magnetic field excited by a magnetic system consisting of

the roma 2, the permanent magnet blocks 3, the ferromagnetic plates 4 and the magnetic wedges 5, are pressed against the surface of the drum 1 and transported to the unloading zone of the magnetic product, where

is separated from the surface of the drum 1 by gravity and centrifugal forces, and is discharged into the receiver 7 for the fermented product.
